2ND STREET CORRIDOR
Supports large volumes of pedestrians, automobiles, busses and bicycles but is busses and bicycles, but is mostly auto-oriented:
• No designated lane for bicyclesg y
• Some pedestrian and transit enhancements

Road DietF l h l i ( l i h • Four-lane to three-lane conversion (one lane in each direction with a center turn lane)
• On-street bicycle lanes in both directions
26
One-Way conversion• Reduce to two through lanes• On-street bicycle lane(s)• Increase parking supply by converting parallel
k d l kparking to diagonal parking
27
One-Way conversion• Reduce to two through lane(s) (one lane west of Broadway)• On-street bicycle lanes• Increase parking supply by converting parallel parking to diagonal

Drop-off Circle• Ongoing coordination with CSUC• Transition one-way to two-way traffic• Allow for northbound U-Turn movement
P d f CSUC• Provide for a gateway entry to CSUC
32
Two-Way conversion• One through lane in each direction• Increase parking supply by converting parallel
parking to diagonal parkingAll f l • Allow for more circulation options
33
Diagonal Parking• Increase parking supply by converting parallel parking to diagonal parking
34
Roundabout• Transition one-way to two-way traffic• Provides enhanced capacity for east-west traffic• Accommodates non-standard intersection alignment• Gateway to downtown
I f f ll d f l• Increase safety for all modes of travel

– Less pavement between intersections
– Reduction in Conflict Points
– Safety
– Shorter queuing distance
– Slower speeds for bicyclists
– Gateway opportunities
– Reduction in GHG
– Reduction in Fuel Consumption

CHICO - TRAFFIC OPERATIONS
Balance LOS and volumes along the 1st Street and 2nd Street Corridors
Maintain acceptable LOS at all intersection
Comparable or improved corridor travel time
46
CHICO - PEDESTRIAN FACILITIES
Crossing enhancements– Intersection bulbouts
Decreased pedestrian crossing distanceIncreases pedestrian visibilityp y
– Road DietFewer lanes to cross (less exposure area)
– Intersection improvementsPedestrian push buttonsPedestrian push buttonsAdditional signal walk-time for pedestrian crossingInstallation of count-down pedestrian signal headsADA upgrades

CHICO - BICYCLE FACILITIES
East-West Corridor Bicycle LanesImproved connections to CSUC and the Annie’s Glen trailColored bicycle lanesColored bicycle lanes
48
CHICO - TRAFFIC CALMING
Lane Reduction– Provides for slower, but steady progression of traffic
Diagonal Parking– Narrows the street encouraging slower driving– Narrows the street encouraging slower driving
Roundabout– Steady flow of traffic at a controlled speed
49
CHICO - ONE-WAY COUPLET
Utilize existing pavement to balance LOS and volumes without additional new infrastructure
Reduced conflicts with turning vehiclesg
Will provide space for on-street bicycle lane(s)
Allows for replacing some parallel parking with diagonal parking
Improved traffic flow
50
CHICO - ROAD DIET
Reduced conflicts with turning vehicles
Slower, but steady flow of traffic
Sh rted edestrian cr ssin distanceShorted pedestrian crossing distance
Allows for installation of bicycle lane(s)
Generally more comfortable for bicyclists and pedestriansGenerally more comfortable for bicyclists and pedestrians
51
1ST STREET/2ND STREET/FLUME STREET ROUNDABOUT
Reduced vehicle conflicts
Steady flow of traffic at a controlled speed
Sh rted edestrian cr ssin distanceShorted pedestrian crossing distance
Improved transition for two-way to one-way traffic
Creates a downtown gatewayCreates a downtown gateway
52
CHICO - DIAGONAL PARKING
Narrows street and provides traffic calming benefits
Goal of increasing parking supply approximately 25% from parallel parking
– Offsets loss where parallel parking is removed
53
A “COMPLETE STREET” APPROACH
I ff fl R d f fl Improve traffic flow issues related to left turn movements from
Reduction of conflicts at the intersection of 1st/ 2nd Street/Flume
2nd Street onto Main Street and Broadway
