39. ROUNDABOUT ADVANTAGES
– Higher vehicle capacity (per lane) than a traffic signal
– 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

41. Bicyclists at Roundabouts
Two Options:
• claim the lane
• use on off-street path 41

42. 42

43. Pedestrians at Roundabouts
Reduced Speeds
15 to 20 mph traffic speeds
Shorter Crossings
About 5 average steps
Cross only one traffic
direction at a time
Fewer Conflicts
Traffic only coming
from one direction 14 Feet to Cross to “Refuge” Area for
Refuge

46. 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

47. CHICO - PEDESTRIAN FACILITIES
Crossing enhancements
– Intersection bulbouts
Decreased pedestrian crossing distance
Increases pedestrian visibility
p y
– Road Diet
Fewer lanes to cross (less exposure area)
– Intersection improvements
Pedestrian push buttons
Additional signal walk-time for pedestrian crossing
Installation of count-down pedestrian signal heads
ADA upgrades
47

48. CHICO - BICYCLE FACILITIES
East-West Corridor Bicycle Lanes
Improved connections to CSUC and the Annie’s Glen trail
Colored bicycle lanes

49. CHICO - TRAFFIC CALMING
Lane Reduction
– Provides for slower, but steady progression of traffic
Diagonal Parking
– Narrows the street encouraging slower driving
Roundabout
– Steady flow of traffic at a controlled speed
49

50. CHICO - ONE-WAY COUPLET
Utilize existing pavement to balance LOS and volumes without
additional new infrastructure
Reduced conflicts with turning vehicles
g
Will provide space for on-street bicycle lane(s)
Allows for replacing some parallel parking with diagonal parking
Improved traffic flow
50

51. CHICO - ROAD DIET
Reduced conflicts with turning vehicles
Slower, but steady flow of traffic
Shorted edestrian crossing
Sh rted pedestrian cr ssin distance
Allows for installation of bicycle lane(s)
Generally more comfortable for bicyclists and pedestrians
51

52. 1ST STREET/2ND STREET/FLUME STREET ROUNDABOUT
Reduced vehicle conflicts
Steady flow of traffic at a controlled speed
Shorted edestrian crossing
Sh rted pedestrian cr ssin distance

53. 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
