  • 9. Area Map 9
  • 10. Plan Area 10
  • 11. Plan Area 11
  • 12. 2ND STREET CORRIDOR Supports large volumes of pedestrians, automobiles, busses and bicycles but is bicycles, mostly auto-oriented: • No designated lane for bicycles g y •Some pedestrian and transit enhancements 121
  • 13. 2nd Street Corridor 13
  • 14. 2nd Street Corridor 14
  • 15. 2nd Street Corridor 15
  • 16. 2nd Street Corridor 16
  • 17. 2nd Street Corridor As a result of the recently developed Transit Center, pedestrian and bicycle use on 2nd Street has increased An integral part of Downtown Multi-Modal Connectivity 17
  • 18. Main and Broadway 18
  • 19. 1ST STREET CORRIDOR The 1st Street corridor is largely underutilized l l d tili d • Limited business fronts • No designated lane for bicycles • Limited pedestrian enhancements 19
  • 20. Roundabout Location 20
  • 21. Roundabout Location 21
  • 22. ISSUES Multiple conflicts at major intersections Heavy left-turn movements Large pedestrian crossing volumes No facilities for bicyclists Desire for D i f more parking on 2nd ki Street Underutilized 1st Street 22
  • 23. PROJECT GOAL • enhancing safety for all travel modes • promoting alternate modes of transportation • converting to a ‘complete street’ • p providing convenient additional parking g p g • revitalizing the CBD without additional infrastructure improvements 23
  • 24. Plan Components Pavement Reallocation Added bike lanes Added di Add d diagonal parking l ki Creation of a one-way couplet Roundabout intersection Connection to park trails 24
  • 25. xxx 25
  • 26. Road Diet• FFour-lane to three-lane conversion (one lane in each l h l i ( l i h direction with a center turn lane)• On-street bicycle lanes in both directions 26
  • 27. One-Way conversion• Reduce to two through lanes• On-street bicycle lane(s)• Increase parking supply by converting parallel parking to diagonal parking k d l k 27
  • 28. 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 parking k 28

  • 30. WEST 2ND STREET CROSS-SECTION 30
  • 31. EAST 2ND STREET CROSS-SECTION 31
  • 32. Drop-off Circle• Ongoing coordination with CSUC• Transition one-way to two-way traffic• Allow for northbound U-Turn movement• PProvide for a gateway entry to CSUC d f 32
  • 33. Two-Way conversion• One through lane in each direction• Increase parking supply by converting parallel parking to diagonal parking• All Allow f more circulation options for l 33
  • 34. Diagonal Parking• Increase parking supply by converting parallel parking todiagonal parking 34
  • 35. Roundabout• Transition one-way to two-way traffic• Provides enhanced capacity for east-west traffic• Accommodates non-standard intersection alignment• Gateway to downtown• IIncrease safety for all modes of travel f f ll d f l 35

  • 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 39
  • 40. Reduction in Conflict Points 40
  • 41. Bicyclists at Roundabouts Two Options: • claim the lane • use on off-street path 41
  • 42. 42
  • 43. Pedestrians at RoundaboutsReduced Speeds15 to 20 mph traffic speedsShorter CrossingsAbout 5 average stepsCross only one traffic direction at a timeFewer ConflictsTraffic only coming from one direction 14 Feet to Cross to “Refuge” Area for Refuge Median Island Pedestrians and Bikes 43
  • 44. SIMILAR ROUNDABOUTS – HUMBOLDT COUNTY/BLUE LAKE 44
  • 45. SIMILAR ROUNDABOUTS – SANTA BARBARA/FIVE POINTS 45
  • 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 48
  • 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 Improved transition for two-way to one-way traffic Creates a downtown gateway 52
  • 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. 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
