  1. Reversing Road Diet – the East 14th Street North Area Reconfiguration Project MTC Technology Transfer Program Seminar on Road Diets Reh-Lin N. Chen, City of San Leandro March 19, 2008

  2. EAST 14TH STREET NORTH AREA STUDY • GOALS & OBJECTIVES • BACKGROUND • DATA ANALYSES • ALTERNATIVES • ALTERNATIVES COMPARISON • RECOMMENDATION & APPROVAL • NEXT STEPS • LESSONS LEARED

  3. GOALS & OBJECTIVES • Quantify traffic parameters • Address vehicular issues • Improve Pedestrian safety • Ensure community input • Recommend an optimal configuration

  4. PROCESS • Collect traffic data • Analyze data • Community Outreach and Information • Surveys • Workshops • Formal Hearings • Council Review and Approval

  5. EAST 14TH STREET NORTH AREA STUDY • GOALS & OBJECTIVES • BACKGROUND • DATA ANALYSES • ALTERNATIVES • ALTERNATIVES COMPARISON • RECOMMENDATION & APPROVAL • NEXT STEPS • LESSONS LEARNED

  6. BACKGROUND • Late 1996 – Four lanes to two lanes with tested median • Late 1999 – One lane each direction with a center two-way left-turn lane • Present - Congestion and pedestrian safety concerns persist • 2004 - Consultant developed potential alternatives • Public Surveys

  7. BACKGROUND

  8. BACKGROUND

  9. BACKGROUND • Retained W-Trans for the study • 1st Workshop on September 29, 2004 • Discussed traffic data and problems • Explained alternatives • Received input at the workshop and via a questionnaire

  10. COMMUNITYPRIORITIES • Easier left turns from side streets • Easier pedestrian crossings • Higher speeds • Don’t change

  14. BACKGROUND Follow-up of 1st Workshop • Additional data collection • Revised questionnaire (i.e., Priorities) to neighbors • Neighborhood Traffic Management Group Meeting in February and April 2005 • Prepared a condensed traffic study report

  15. BACKGROUND • Presented to Planning Commission at their November 11, 2005 meeting • Presented to Facilities Committee at their January 25, 2006 meeting

  16. EAST 14TH STREET NORTH AREA STUDY • GOALS & OBJECTIVES • BACKGROUND • DATA ANALYSES • ALTERNATIVES • ALTERNATIVES COMPARISON • RECOMMENDATION & APPROVAL • NEXT STEPS

  17. EXISTINGCONFIGURATION

  18. EXISTING CROSS-SECTION • 17-foot wide center TWLTL • Two 12-foot wide travel lanes • Two 6-foot wide “bicycle/buffer” areas • Two 7-foot wide parking lanes • Total curb-to-curb width = 67 feet

  19. EXISTING CROSS-SECTION

  20. COLLISION SUMMARY

  21. PEDESTRIAN COLLISIONS

  22. EXISTING CONDITIONS SUMMARY • Traffic volumes have increased 17% for ADT and 14% for p.m. peak hours since 1994 • Weekday traffic volumes are typically higher than weekend • 65% of traffic is pass-thru traffic • Collisions have been trendinghigher

  23. EXISTING CONDITIONS SUMMARY • 33% Pedestrian collisions were potentially correctable • Average speed in p.m. peak hour – 17.5 mph (NB) and 19 mph (SB) • Most signalized intersections are LOS C or better, except LOS D at Dutton • Most un-signalized intersections are LOS C or better, except westbound Oakes is LOS D

  24. CHALLENGES • Pedestrian safety concerns • Traffic congestion at East 14th/Dutton • Side-street access at un-signalized intersections is difficult

  25. EAST 14TH STREET NORTH AREA STUDY • GOALS & OBJECTIVES • BACKGROUND • DATA ANALYSES • ALTERNATIVES • ALTERNATIVES COMPARISON • RECOMMENDATION & APPROVAL • NEXT STEPS • LESSONS LEARNED

  26. ALTERNATIVES • Alternative 1 – Existing Conditions • Alternative 2 – Four-lane Configuration • Alternative 3 – Modified 3-Lane Configuration with Pedestrian Safety Features • Alternative 4 – Two Northbound Lanes and One Southbound Lane

  27. ALTERNATIVE 1 – EXISTING CONDITION

  28. ALTERNATIVE 1 - EXISTING CROSS-SECTION

  29. ALTERNATIVE 2 – 4-LANE CONFIGURATION

  30. ALTERNATIVE 2 - CROSS-SECTIONS

  31. ALTERNATIVE 2 - CROSS-SECTIONS

  32. ALTERNATIVE 3 – MODIFIED 3-LANES WITH PEDESTRIAN SAFETY FEATURES

  33. ALTERNATIVE 3 - CROSS-SECTION

  34. ALTERNATIVE 4 – TWO NORTHBOUND LANES AND ONE SOUTHBOUND LANE

  35. ALTERNATIVE 4 – CROSS-SECTION

  36. ALTERNATIVE 4 – CROSS-SECTION

  37. EAST 14TH STREET NORTH AREA STUDY • GOALS & OBJECTIVES • BACKGROUND • DATA ANALYSES • ALTERNATIVES • ALTERNATIVES COMPARISON • RECOMMENDATION & APPROVAL • NEXT STEPS • LESSON LEARNED

  38. TRAVEL TIME AND LOS COMPARISON

  39. QUEUING AT DUTTON AVENUE P.M. PEAK HOUR

  40. SUMMARY ALTERNATIVES COMPARISON

  41. COMMUNITYPRIORITIES • Easier left turns from side streets • Easier pedestrian crossings • Higher speeds • Don’t change

  42. EAST 14TH STREET NORTH AREA STUDY • GOALS & OBJECTIVES • BACKGROUND • DATA ANALYSES • ALTERNATIVES • ALTERNATIVES COMPARISON • RECOMMENDATION & APPROVAL • NEXT STEPS • LESSONS LEARNED

  43. ALTERNATIVE 4 – MODIFIED WITH PEDESTRIAN SAFETY FEATURES • 11-foot wide center TWLTL • Three 11-foot wide travel lanes (2 NB & 1 SB) • Two 4.5-foot wide “bicycle/buffer” areas • Two 7-foot wide parking lanes • Pedestrian Safety Features at selected un-signalized intersections

  44. RECOMMENDATION & APPROVAL • Staff requested that Planning Commission recommend Modified Alternative 4 to Council for implementation • Planning Commission split vote between Alternatives 2 and Modified Alternative 4 with one abstention on November 11, 2005

  45. RECOMMENDATION & APPROVAL • Facilities Committee reviewed the project and favored Modified Alternative 4 on January 25, 2006 • Staff recommends Modified Alternative 4 with pedestrian safety features • City Council adopted Resolution approving Modified Alternative #4 as new configuration, May 1, 2006

  46. MODIFIED ALTERNATIVE 4 – TWO NORTHBOUND LANES AND ONE SOUTHBOUND LANE

  47. EAST 14TH STREET NORTH AREA STUDY • GOALS & OBJECTIVES • BACKGROUND • DATA ANALYSES • ALTERNATIVES • ALTERNATIVES COMPARISON • RECOMMENDATION & APPROVAL • NEXT STEPS • LESSONS LEARNED

  48. NEXT STEPS • Collaboration with Caltrans and other agencies • Design • Implementation through 2007-2008 Capital Improvement Program (CIP)

  49. EAST 14TH STREET NORTH AREA STUDY • GOALS & OBJECTIVES • BACKGROUND • DATA ANALYSES • ALTERNATIVES • ALTERNATIVES COMPARISON • RECOMMENDATION & APPROVAL • NEXT STEPS • LESSONS LEARNED

  50. LESSONS LEARNED • Community inputs are as crucial as the traffic data • Road diets may not work for all especially when collisions and congestion/bottleneck worsen traffic conditions
