2009 Travel Time Study Update
A statewide travel time study was conducted in 2000 to determine the relationship between actual travel speeds and
roadway class/posted speed limit. In 2003, this study was updated to stratify the sample draw by posted speed limit
which had since become available as an attribute in the state system roadway information database. In August 2009,
the study was updated again to revise the travel speeds on 65 MPH freeways. This is being done because in July
2009, differential truck speed limits on 65 MPH freeways were removed and it is expected that this will increase
overall drive speeds on these roads. The study was conducted using floating car methodology following all of the
procedures of the previous study to which the reader is referred for details.
For this study, all segments from the previous studies with 65 MPH posted speed were resurveyed, including those
without a speed limit change (non-interstates). The same segments were rerun so that just the changes in speeds
over time could be investigated without clouding the issue with sampling noise. Figure 1 and Table 1 shows the
sample segments as both a map and a table respectively.

Table 1. Speed Study Segments
After collecting the data, it was entered into a spreadsheet and edited/cleaned. During this process several segments
were dropped from the study. Sample segment 1101 was dropped in its entirety since the section was in a
construction zone with reduced speed limits. For the same reason, part of segment 214 was removed as well as the
off ramp at the end of segment 101 (note, ramp speed updates were not part of this update, however, to be consistent
with the previous runs, sample segments including ramp sections were run the same way in this update). A small
amount of segment 1112 was removed in the IR 80/680/SR 11 interchange area as being inconsistent with the
previous segment definition.
Following the data checking/editing, the segments were grouped as in the previous study to produce a single speed
estimate per study segment. These segment specific speeds were then compared to the speeds on the same segments
from the previous study; these comparisons are shown in the graph of Figure 2. As the figure shows, generally the
speeds were higher in the new study.
Figure 2. Comparison of Speeds from the Original and Updated Studies
Following this comparison the averages by speed table cell were calculated and compared to the old speed table
values as shown in Table 2. In this table a posted speed of 58 means 60 for cars, 55 for trucks, while 63 means 65
for cars and 55 for trucks. The one segment with PS 58 in the CBD class drops from the study. Indeed, removal of
this segment is the main reason for the speed increase on CBD routes (there are very few CBD 65 MPH freeways
and only 4 segments in the study). Partly for this reason and also because the 65 MPH speed shown for this class
was rounded up from 64.6, a speed of 64 MPH was used for this group in the final speed table. For urban routes,
there are only 8 segments in the current study versus the original 9 due to the removal of segment 1101 as previously
mentioned. Seven of the segments are Interstates with 65 MPH for all vehicles while only one has the differential
speed limit. The table shows a marked difference between the two, however, 1 sample segment isn’t enough to
draw conclusions. Since the 67 MPH speed shown was actually rounded up, the class average of 66 MPH was used
for this class in the final speed table. For rural segments, 19 segments were run with 14 being interstates and 5 not.
This is one more segment than existed in this class originally because segment 105 was not run previously due to
construction at that time. While the 65 MPH routes are slightly faster than the 63 MPH, the difference is less than 1
MPH. Interestingly, when the study was done originally, the non-interstate routes were faster because of their lower
percent trucks. With the increased truck speed limit, the interstates are now faster but not by much. The revised
speed for all routes of this class will be 68 MPH.

Based upon the previous discussion, the speed tables were updated by modifying 3 cells in both the total and run
time speed tables (rural, urban and CBD 65 MPH routes). The other 65 MPH cells for arterial streets (which hold
dummy values derived from these 3 cells in the original study) were not changed as they generally do not exist and
there is no data one way or the other to support the values in these cells. Table 3 compares the old and new run time
speed tables, total time speed was modified similarly.

2003 Speed Study Update
December 2003
The following technical memorandum briefly describes the 2003 update to the statewide speed study. This report is
not all inclusive and should be considered an addendum to the 2000 speed study report.
The 2000 speed study was a stratified random sample drawn from the road inventory database. The stratification
was based on various facility and area types. No stratification was done on posted speed since this did not exist in
the database at the time even though this was anticipated as the most important explanatory variable. The intent was
to simply do linear regressions across posted speed in each category. The problem that arose, however, was that
posted speeds were heavily clustered at only a few values in each category which left large parts of the resulting
speed table based on limited or nonexistent data. The 2003 update targeted specific combinations of posted speed
within the original categories using the statewide model network to draw the sample. This network contains all
collectors and better but does not contain all local streets. However, to maximize the impact of the limited
resources, local street categories were not updated in 2003 so this posed no problem.
Figure 1 shows the distribution of the study. Black segments are the 2000 sample, blue is the 2003 and red are
additional adjacent segments run with the 2003 (these additional segments existed in the 2000 sample as well but are
not shown). The add on segments are simply adjacent segments with the same characteristics of the sample segment
which are added to produce sample segments of from 1 to 2 miles in length.
The data was collected in August/September 2003. Unlike the 2000 study, only off-peak runs were made since the
intention is to update the free flow speed tables. Beyond that, the same procedures were used as in the 2000 study.
After cleaning and editing the data, segment specific distance, total time, run time and average stops were
calculated. Run times subtracted out control point stop time. Two departures from the 2000 analysis were made at
this point, first the mid block stops were not removed when calculating run time since this delay won’t be accounted
for in intersection modeling. Second, the acceleration/deceleration delay were no removed on a segment by segment
basis since many segments are too short to fully handle this delay. This delay was later accounted for after grouping
the segments as discussed below. The 2000 data was reanalyzed to use this same method. While doing this, a
number of corrections were made to the 2000 data and a couple of samples were dropped as unusable.
It was discovered while developing the 2003 sample that 12 of the 14 samples in category 2 were actually freeways
belonging in category 1. Thus category 2 (rural 4 lane arterials) was dropped. When reanalyzing the 2000 data
these 12 samples were moved to category 1 while the remaining 2 (samples 205 and 210) were added to category 3
(rural 2 lane arterials) to create a generic rural arterial category.
Pivot tables were then used to consolidate the 2000 data into facility type/posted speed categories by sample
segment. Thus unlike the 2000 analysis where every segment of every sample was analyzed individually, all
segments with the same posted speed on a given sample were combined and analyzed as a unit for this analysis.
This method is the statistically correct one given the way the sample was drawn since to analyze all segments
individually biases the results to samples with more control points.
This same process was followed for the 2003 data. One difference, however, was that segments were flagged based
on the posted speed category they were drawn for. Because a posted speed stratification was used for this sample,
segments falling outside the intended posted speed were removed since to include them would bias the other posted
speed categories they fell in. For this purpose, posted speeds on the even 10’s were included if matching the next
highest category (thus if a segment was drawn for 45 MPH, it was retained if it had a posted speed of 40 MPH or 45
MPH). The reason is that even 10 categories are rare so when the posted speed stratification was made, no samples
were drawn from independently from these categories, rather they were lumped for sample selection purposes. This
process resulted in 374 out of 930 miles of studied roadway (40%) being excluded from the study including 57 of
the 276 sample segments being disregarded entirely because the sampled posted speed didn’t actually exist
anywhere on the sample.
After the segments were consolidated, acceleration/deceleration delay was then added on these longer pieces. A
check was made to insure all segments were long enough to handle the distance necessary to fully develop this
acceleration/deceleration (which they were for all but 2 cases which were addressed by placing an upper bound on
the running speed). The precise details of these various computations won’t be addressed here, for the most part the
formulas etc. can be seen in the spreadsheet data2003.xls. Two exceptions are the computation of segment distances
and the intermediate pivot tables used to develop the consolidated segments. The computation for distance involved
comparing with adjacent records and the formula was replaced with values so the data could be resorted afterwards.
To pivot tables necessary to consolidate the data had to be done separately for each variable and then the values
copied and combined (the reason being that Excels pivot tables place multiple variables row-wise but they were
needed column-wise because the segment ID’s had to be row-wise since Excel doesn’t allow enough columns to do
them column-wise).
Figure 2 shows the number of segments in each facility type/area type/posted speed category from the 2000 sample
and the combined 2000/2003 sample. This clearly illustrates the areas that were targeted in 2003 (namely, lower
speed rural arterials and collectors and higher speed urban arterials and collectors.) Figure 3 shows the revised total
and run time free flow speed tables developed from this study. Note that these values have been smoothed to
provide for logical, consistent values. In performing this smoothing, cells that had over 10 sample segments were
fixed, those between 3 and 9 samples were semi-fixed (i.e., they could be changed but reluctantly) while values in
cells with 2 or less samples were modified as necessary to produce the desired consistency. Figure 4 shows the total
time speeds graphically.

Introduction
A statewide travel time study was conducted in the summer of 2000. This study was conducted primarily to gather
data to be used in the statewide travel demand forecasting model being developed by ODOT and its consultants.
The study was conducted on over 300 1 to 2 mile long segments of roadway throughout the state. These segments
were randomly selected within certain categories and travel time was measured as documented in the next section.
Travel time was measured using the floating car method and therefore represent the travel speeds of cars, not trucks.
The results of the study are presented in the final section of this report.
Study Description
The travel time study was conducted following guidelines set forth in the "Travel Time Data Collection Handbook"
(FHWA-PL-98-035) and as further elaborated in ODOT's "Model Specification and Data Collection Program For
Small MPO Study Areas in Ohio" (see excerpt in Appendix A).
For this study, the roadways in Ohio were stratified into the following categories:
Figure 1. Roadway Classification Scheme
For each category (except ramps which are measure as part of their connecting freeway segment) 14 segments were
selected for study. This number was based on the computations shown in the Appendix (note that the small universe
correction factor was not needed due to the relatively large number of segments on a statewide basis). These
segments were selected using the Road Inventory database.
Data from both the state and local files was used. The class codes listed above were added as an attribute to this
data using the functional class and number of lanes fields (for non-state system routes the width field was used, any
width less than 39 feet was assumed to be a 2 lane road). While functional class could provide the distinction
between rural and urban roads, there is no field in the road inventory that distinguishes CBD areas. This distinction
was deemed necessary for travel modeling purposes so roadways in CBD areas were determined by selecting road
inventory segments that fell within the CBD polygons shown in Figure 2. These polygons were created using the
MPO area travel demand forecasting model network area types.
Once classified, the data was then dynamically segmented using this new attribute. Within each class the number of
miles of roadway was computed. This value was divided by 14 to obtain the sampling interval. The milage at
which the first segment was selected was determined randomly, additional segments were selected at the sampling
interval beginning at this first segment. The table below shows the sampling results for the rural area. Similar
tables result from sampling the urban and cbd areas.
This table shows for example that for class 2 (rural 4+ lane arterials) that there are 3.59 miles on the county system,
1135.71 miles on the state system and 0 miles on the township system. There are a total of 1139.3 miles statewide.
Dividing this by 14 gives a sampling interval of 81.38 miles. The first location was selected after accumulating
21.16 miles, the second at 102.54 etc. The segments were in no particular order in the database.

Figure 2.
After selection, the selected locations were assigned a 4 digit ID (the first 2 digits being the class code, the second 2
being the unique location (1-14) within the class) and compiled in a database. From there the locations were plotted
with their ID labels using GIS. Street maps were referenced into this plot and using the plotted locations, street
names and from/to cross streets resulting in approximately 1 (urban) or 2 mile (rural) sections were determined and
entered into the database. Using the plotted locations, data collection schedules were then developed to minimize
the travel time between segments. Figure 4 shows the segments selected for analysis in the travel time study. Note
that the segments shown are the road inventory segments as dynamically segmented by the categories in Figure 1.
The actual length of road run was a 1 to 2 mile segment regardless of the length of the road inventory segment.
The data was collected using a DMI equipped vehicle. Checkpoints were established along the subject route at all
intersections involving traffic control on the route as well as rail crossings and changes in speed limit, number of
lanes or directional status (oneway versus twoway street). The travel time and distance between each checkpoint
was recorded using the DMI. The form used to collect this data is shown in Figure 5.
Each segment was run 4 times in rural areas and 6 times in urban areas. For two way streets half the runs were made
in each direction. Multiple runs were needed on each segment to obtain a statistically significant measure of the
travel time on the route. The number needed was calculated as shown in the Appendix. Generally routes with
greater variance in travel time require more runs. Since the actual variance is unknown, the roadway type can be
used to approximate this variance. The roadway type is in terms of signal density (higher density gives greater
variance), however since this also is unknown in general, the area type was used as a surrogate (cbd=high density,
urban=medium, rural=low. Using the generalized variances given in the Handbook and rounding yields 4 runs on
rural, 6 on urban and 8 on cbd, freeways always received 4 runs due to their lower variance. All urban and cbd
segments were run in both the off-peak and PM peak periods (thus an urban segment would have a total of 12 runs).
Rural segments were run off-peak only. In order to keep the number of peak and off-peak runs required in balance
with the number of peak-off peak hours available each day, the number of cbd runs was reduced from 8 to 6.

point numbering). Distances are in miles and represent the distance from the beginning of the segment.
Further data processing will populate the distance between checkpoints later. No distances are given in the
noncardinal direction because they can be calculated from the cardinal distances. Times are stored in
minutes/seconds from the beginning of the run. All stop time was kept track of separately to allow it to be
segregated from run time. Most stops occur at the checkpoints (usually intersections) so this time was kept
track of by simply noting the elapsed seconds when the vehicle stopped and when it resumed. Occasionally
stops occur at other locations, these are indicated with a reason code and the total seconds stopped.
The data processing began with some clean up of the data and conversion of raw recorded cumulative times
and distances to segment values. As roughly one-quarter of the road segments used did not have a posted
speed limit recorded, such limits were estimated based on prima facie speed guidance from the Ohio
MUTCD. Additionally, because only stopped delay was recorded in the field, added time for vehicle
acceleration and deceleration from stop to posted/estimated speed was used, using estimates of 3.5
mph/second for vehicle acceleration and 5.0 mph/second for deceleration. Street segment numbers and
distances were not field recorded in the non-cardinal direction and were added. Data entry locations for
some streets were sometimes moved depending on where PM peak hour data was recorded. On and off-
ramps were initially entered with the corresponding freeway road codes, these were manually reassigned to
ramp codes based on checkpoint descriptions. Speeds were calculated for each run of each roadway
segment to identify errors in the database. Any road segments with clearly illogical speeds for which
coding errors could not be easily identified and corrected were not used in the analysis.
After processing and cleaning the data, tables of total and running speed by posted speed were created.
These were created in 2 ways, by averaging for all roadways of a certain class and posted speed and by
developing regression equations within each roadway class with posted speed as the independent variable.
The regression method has the advantage of producing speed values across a range of posted speeds even if
their were no observations for certain posted speeds. The drawback is that the regression curves may not
be applicable for ranges of posted speed where no or few observations exist. The use of regression analysis
to develop speed values over a range of posted speeds was necessitated by the fact that the sample was not
stratified by posted speed. The reason was that posted speed was only partly populated in the road
inventory state system file and not at all in the local file.
For many roadway classifications nearly all the sampled segments have the same or only a few posted
speeds. Therefore, the final speed table was developed using a combination of the regression results and
the average speeds by posted speed. Figure 7 below describes how the final speed table values were
determined for each roadway classification/posted speed combination. Note that for the rural
classifications, almost all observations had a posted speed of 55, thus while the regression results were used
to populate the speed table, values for posted speeds other than 55 should be regarded with some caution.
In addition, it should be noted that a number of roadway classes were compressed upon examining the data.
This was done when there was no significant difference in the speed results for related classes, particularly
when the slight differences that did exist were illogical.
For those roadway classifications where regression equations are recommended for use, the correlation
between actual and posted speeds was quite poor. It is slightly higher for running time than for overall
travel time. Average r-square values in the PM peak are .16 for overall travel time and .25 for running time
without intersection delay, while for the off-peak period the average r-square value is .24 for overall travel
time and .28 for running time. In addition, for roadway segments used in the analysis, the standard
deviation of the running time was less than half that of overall travel time with intersection delay (with
coefficient of variation being 13% for running time compared to 24% for overall time). This indicates the
explicit modeling of intersections within travel forecasting would provide better assignment results when
using speed table lookups rather than link specific speeds.
The class 4 and 7 roadways (4+ lane rural collectors in flat and hilly areas) were compressed thus
indicating that hilly terrain does not impact speeds on multi-lane roads. It should be remembered however,
that all speed data presented herein was derived for cars, not trucks. Had a heavy truck been used, some
degradation in speed in hilly terrain would be expected. Classes 2 and 3 (2 and 4+ lane rural arterials were
compressed for the same reason, the data shows that for equal posted speed the travel speed on these types
of roads is independent of the number of lanes. The key difference between the 2 lane and 4+ lane roads is
that the posted speed tends to be higher on the 4+ lane arterials. The urban and cbd roadway classes were
combined in the same way , for these roads other factors such as intersection delay are far more important
than number of lanes in determining travel speeds. In fact, the raw data shows that for equal posted speed,
the 2 lane urban roads had higher running speeds than the 4 lane, this is probably an indication of the access
density that tends to exist along urban 4+ lane roads compared to 2 lane roads. Roadway classes that have
very restricted ranges of posted speed such as urban local roads (25 MPH), rural local roads (55 MPH) and
ramps were typically given a single average value of speed rather than producing separate values by posted
speed. This has the potential to create incorrect speeds for unusual circumstances where for example a
rural local road has a posted speed of 25 MPH in which case its speed value from the speed tables herein
would be too high.

Study Results
Figures 8 and 9 presents the final speed table derived from the present study. Figure 8 reflects the speeds
based upon total travel time and Figure 9 the running time speeds (intersection delay removed). Boxed
values in these tables are speeds which should be used with extreme caution or not at all since they
represent conditions which were not present in the survey data set. These boxed values were derived by
simply extending the last valid entry into the boxed region rather than applying the regression results which
were meaningless in these ranges.

Figures 10-18 show various combinations of the speed data plotted for comparison purposes. Each chart
shows the speed table travel speed versus the posted speed limit. Figure 10 shows values of the travel time
speed for all of the rural classifications while Figure 11 shows the same data for the PM peak period on the
urban classes. Note that in general, higher functionally classed roadways have higher speeds than lower
classes. One notable exception is on 4+ lane collectors. The regression equation for these roadways has a
steep slope giving speeds lower than lower functional classes for low values of posted speed and higher
values for higher posted speeds. The reason is that when rural collectors go to 4+ lanes with low posted
speeds they tend to be in small village which gave urban characteristics which give lower speeds than 2
lane rural roads with low posted speed which tend to be in residential areas. At higher posted speeds the 4+
lane collectors have higher speeds than comparable 2 lane roads as expected.
Figures 12 and 13 compare the peak and off peak speeds on the urban roads. Figure 12 is for the freeways
and arterials while Figure 13 is for the collectors and locals. In general the data shows slightly lower
speeds during the peak period, however, in general the values are very close indicating the relatively
uncongested nature of the random sample. Obviously, had the sample been targeted to congested areas, a
greater impact would be seen. Additionally, some background level of congestion is present even during
the off peak period as indicated by the lower speeds on urban roads compared to rural. Note that the cbd
area collectors had a slightly higher speed during the peak than the off peak, the values are extremely close
and reflect statistical noise, the values are merely an indication that there is no statistical difference in
speeds on urban collectors between the peak and off-peak periods.
Figures 14 and 15 compare the average travel speed with the running speed. In all cases the running speed
is higher than average speed as it must be since running speed does not account for intersection delay.
Note that the running speed and average travel speed curves are parallel for like road classes indicating a
relatively uniform impact of intersection delay across posted speeds. It should also be noted that the
freeway running time is equal to the average travel time since there is no intersection delay.
Figures 16-18 compare all roadway classes for each of freeways, arterials and collectors respectively.
These figures allow the comparison of the impact of various conditions including rural versus urban area
type on the speed of roads with like functional class. Note that for freeways, rural and urban are closer
together while cbd is much slower. For arterials urban and cbd are close together while rural is much
faster. For collectors there is about an equal amount of speed reduction going from rural to urban as from
urban to cbd.
Conclusion
This report has documented the results of the travel time study conducted by ODOT. Results have been
shown which will be useful for developing speed values for travel demand forecasting model. A key
finding of this report has been that travel speed is insensitive to the number of lanes but does depend on
roadway class and posted speed.
Appendix A Excerpt From "Model Specification and Data Collection Program For Small MPO Study Areas in
Ohio" on How to Conduct Speed-Delay Studies
D. Speed Delay Study
A speed/delay study is necessary to establish area specific network speeds for each MPO area. ODOT will
conduct such a study on a statewide basis and MPO's are free to use the results of this study for their area,
though collection of posted speeds will still be required. MPO's are encouraged to conduct their own
studies to produce area specific values. A side benefit of the speed/delay study is that it provides a
database for congestion management activities and is a valuable resource in of itself outside the travel
model context.
In general this study should follow the guidelines contained in the Travel Time Data Collection Handbook
(5). A test vehicle method should be employed using a floating car/average car driving style. This study is
sufficiently large that it may require use of a consultant, however, a crew of summer interns could complete
the study in a single summer (significantly less time for the smallest areas) for significantly less cost.
All roadways in the study area which are included in the forecasting network should be grouped based on
the following two classifications which are defined by the proposed speed table format discussed in
Chapter 2:
Areatype: CBD (includes Fringe), Urban (includes Residential, Outlying Business District), Rural
Facility Type: Freeway/Expressway (Limited Access)
Arterial (4+ Lanes)
Arterial (2 Lanes)
Collector
Local
Township Roads
Centroid Connectors
Ramps
Each roadway should be broken into approximately 2 mile segments for arterial streets and 3 mile segments
for freeways. These segment breaks should occur at interchanges/intersections. Segments should be
defined such that the entire segment is in the same category. The segment should also not change between
a 1 way and 2 way street. The segment length criteria are rough guidelines only, with the other factors in
this paragraph providing the primary means for defining segments.
A random sample of segments within each category should be selected for speed delay runs based on the
following parameters:
Coefficient of Variation: 0.20
Z Statistic (90% confidence): 1.845
Relative Percent Error: 10%
This yields a sample of 14 segments per category. These values are based on guidance given on page 2-10
of (5). Next the number of segments in each category should be adjusted for the population size using the
correction equation:
n = n'/(1+n'/N)
where
n = sample size
n' = uncorrected sample size (always 14 for this study)
N = population size
Thus if a certain category had 30 segments total, the sample required would be:
n = 14/(1+14/30) = 10 segments
Once the segments to study have been determined, the number of runs to make on each segment should be
determined as follows:
Category Number of Runs
Freeways 4
Rural Nonfreeway 4
Urban Nonfreeway 6
CBD Nonfreeway 8
These values are based on Tables 3-3 and 3-4 of (5) using a 90% confidence level with a 10% relative
error. The freeway categories in these tables have been collapsed since the higher volume categories
generally don't apply to the small MPO's and the arterial categories have been translated from signal
densities to area types. Also, the number of runs required has been rounded down to even numbers so that
the runs can be apportioned equally by direction for 2 way streets.
The indicated number of runs can be conducted at any time of the day for rural categories. For urban and
CBD categories, the indicated number of runs should be repeated in both the peak (6 AM to 8 AM, 4 PM to
6 PM) and off peak periods (thus doubling the number of runs needed on those routes). Only the off peak
(free flow) speeds are strictly necessary for the equilibrium traffic assignment algorithms, however, peak
(congested) speeds should be obtained as well for comparative purposes and to use in all-or-nothing
assignments.
Travel time runs should be made Monday through Thursday and should avoid the day before and after a
holiday weekend.
Conduct of the study can use any of the available test vehicle methods including manual recording, distance
measuring instrument (DMI) or global positioning system (GPS) technology. Checkpoints should be
established throughout each segment to delimit major intersections, changes in roadway characteristics or
other features of note which could affect travel time data. The handbook (5) suggests checkpoint spacing
of about 025 to 0.5 miles, however, this is only a rough guide since the characteristics of the previous
sentence will control. For consistency, segments should be initiated after passing through any intersection
at checkpoint 1, while any delay due to an intersection at the last checkpoint should be included in the
segment.
Run time and stop delay time should be recorded separately in the studies. The reason for any stop delay
should be noted. Speed delay runs will be discarded for routes experiencing major incidents (accidents
construction etc) and will be conducted at another time if possible. Stop delay for minor incidents or those
whose stop delay can be isololated (such as trains) will be removed prior to the computation of average
facility speeds.
When a centroid connector segment is selected, a combination of local streets in the selected zone should
be picked which give approximately the same length as the centroid connector.
Speeds will be calculated as a space mean speed by dividing distance traveled by the travel time required.
In addition to keeping track of travel times and delay, the posted speed limit, number of lanes and direction
status (oneway vs twoway), presence/absence of parking, intersection control at each intersection and turn
lane presence on the intersection approach should all be collected so that their effects on speed can be
studied. It is generally useful to run the route once without collecting speed/time data to record this data as
well as to establish the location of the listed control points (and the distance between points if doing so
manually).
