  46. 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. 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. 48. CHICO - BICYCLE FACILITIES East-West Corridor Bicycle Lanes Improved connections to CSUC and the Annie’s Glen trail Colored bicycle lanes 48
  49. 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. 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. 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. 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 Improved transition for two-way to one-way traffic Creates a downtown gateway 52
  53. 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 53
  54. 54. A “COMPLETE STREET” APPROACH I ff fl Improve traffic flow R d f fl Reduction of conflicts issues related to left at the intersection of turn movements from 1st/ 2nd Street/Flume 2nd Street onto Main Street near Camellia Street and Broadway Way Bridge Enhance bi l E h bicycle Increase pedestrian I d i circulation on 1st safety especially at Street and 2nd Street g intersection crossings with connections to Extension of CSUC downtown business Increase parking I ki potential by i t ti l b increased d capacity traffic on West 1st Increase bicycle safety Street 54
