RECOMMENDATIONS
~
Construct additional laneage on Forest Avenue to permit two approach lanes. The left turn lanes should align opposite each other.
Since a minimal number (4%) of vehicles turn left from southbound Ford Blvd. and since this left turn can be made at another intersection, it is recommended that this left turn be prohibited. Use an overhead case sign with the legend "NO LEFT TURN" to accomplish this. Also, use two post-mounted "NO LEFT TURN" symbol signs, one on the n~ar right hand corner and one on the far left hand corner.
Erect Overhead Lane Use Control signs on southbound Ford Blvd. Also, erect a "RIGHT LANE MUST TURN RIGHT" (R3-7) sign on southbound Ford Blvd. to indicate a turn movement for this lane.
The new signal timing would include a 70 second cycle with a 64-36 percent split favoring Ford Blvd. and six percent (4.2 seconds) yellow clearance interval for each phase. The north and southbound traffic would operate for 50 percent (35.0 seconds), then the southbound traffic would get a red indication, while the delayed left turn and cotitinued thru movement for northbound traffic would operate for the remaining 14 percent (9.8 seconds). Traffic on Forest Avenue would be allowed 36 percent (24.2 seconds) to operat·e.
Apply pavement markings including pavement arrows to stress the function of each lane.
Skidometer tests have been ordered for all approaches to this intersection because of the substantial amount of wet pavement accidents.

RECOMMENDATIONS
In an attempt to reduce the right-angle accidents, it is recommended that this location be converted to a 4-Way Stop. A 4-Way Stop will require two 36 in. Stop signs, two 36 in. Stop signs, two 36 in. Stop . Ahead signs and four "4-Way" Panels. The flashing beacon will also have to be converted to four red lenses.
Install an overhead street light~ ing system at this location.

HOLMES ROAD AT FORD BOULEVARD
Operational Analysis:
Holmes Road intersects Ford Boulevard to form a "T" intersection operating under traffic signal control. The right-ofway assignment is based on a 70 second cycle with a 64-36 ~plit favoring Holmes Road and clearance intervals of seven percent (4.2 seconds). A leading green arrow for left turns off westbound Holmes Road of 11 percent (7.7 seconds) is included in the phasing of this signal. A shopping center drive, located directly across from Ford Boulevard, has no traffic controls.

Miscellaneous 0 1 3 4
Total 10 9 9 28
The miscellaneous types include two right-angles, one head onleft turn and one ran off roadway accident. The accident rate was 2.1 ACC/MV.
The utilization of a left turn green arrow that terminates without a yellow clearance interval is not in accordance with the Michigan Manual and creates an accident potential at this intersection.

RECOMMENDATIONS
Change the present signal operation to a three phase system. Install a vertical signal arrangement (4 lenses) for westbound Holmes Road and green arrows for the right turn lane on eastbound Holmes Road and northbound Ford Boulevard. The new signal timing would include a 70 second cycle with six percent (4.2 seconds) yellow clearance intervals. The three phases would include one phase for east and westbound Holmes Road traffic (40 percent- 28 seconds), one phase for westbound Holmes Road traffic including the left turn movement on Holmes Road and the right turn from Ford Boulevard (20 percent -14 seconds), and one phase for northbound Ford Boulevard including the right turn from eastbound Holmes Road (40 percent- 28 seconds).
Apply pavement marking including ~avement arrows to stress the function of each lane.
Extend the flares and tapers on Holmes Road to provide enough laneage for vehicles to maneuver around waiting vehicles.
4. Close off the Shopping Cente~ service drive. There are other drive openings available to the east that provide access to the shopping center.
5. Erect two R3-7 "RIGHT LANE MUST TURN RIGHT" signs for the eastbound Holmes Road right turn lane.

PACKARD STREET AT HEWITT ROAD
Operational Analysis:
Packard Street intersects Hewitt Road to form a right-angle intersection operating under signal control. The right-ofway assignment is based on a 70 second cycle with a 57-43 percent split favoring Packard Street and yellow clearance intervals of seven percent (4.9 seconds). There is also a ten percent (7.0 second) left turn green arrow for east and westbound Packard Street.

Change the Bi-Directional Target Arrows to Directional Target Arrows (96 x 48) on both north and southbound Wittaker Road,
Apply pavement markings - center line, edge line and stop bars -to aid motorists during periods of darkness.
Create a safe landing area by removing the trees, bushes, poles, etc., south ,of Stony Creek Road.
4. Relocate the guida sign which is in target position for southbound Whittaker Road to a position north of the intersection.
5. Erect Road Name signs (D3-2a) on the existing Side Road warning signs on Whittaker Road on both sides of the intersection.
6. Erect delineators at 50 foot intervals along the west side of Whittaker Road for a distance of 500 feet each direction from Stony Creek Road to provide visibility at night.

Change the present signal operation to three phases. The new signal timing would include a 70 second cycle with six percent (4.2 seconds) yellow clearance intervals. The three phases include one for east and westbound Textile Road traffic (40 percent- 28.0 seconds), one for westbound Textile Road traffic including the right turn from McKean Road (33 percent- 29.7 seconds) and one for northbound McKean Road traffic including the right turn from McKean Road (33 percent- 29.7 seconds). A vertical signal arrangement (4 lenses) .should be installed for westbound Textile Road.
Apply pavement markings including pavement arrows to stress the function of each lane.
Reconstruct additional laneage to provide two approach lanes per approach.
Erect two R3-7 "RIGHT LANE MUST TURN RIGHT'' signs for the eastbound right turn lane on Textile Road.

TEXTILE ROAD AT BRIDGE ROAD
Operational Analysis:
Textile Road intersects Bridge Road to form a four-legged intersection. The south leg is a private drive leading into the Ford Motor Company plant. Traffic is controlled at this intersection by two signal heads which operate on flasher (yellow for Textile Road and red for Bridge Road and the private drive) except when there is a shift change at the adjacent Ford plant. Included in the phasing of this signal is a 12 percent (7.2 seconds) leading left turn arrows for left turns off east and westbound Textile Road.

1. Signalized intersections should have two approach lanes to provide adequate capacity at these intersections.
2. Green arrows shouldn't be terminated without going through a yellow and red indication as per the Manual.
3. A program should be initiated by the county for removing vision obstructions that are located in clear vision areas at intersections through the county.
4. Approximately 18 percent of the required regulatory signs on the Washtenaw County Primary Road System are in need of maintenance or new installation.
5. Approximately 20 percent of the required warning signs are in need of maintenance or new installation.
