1 City of Phoenix Street Transportation Department 1 7 th Avenue and 7 th Street Reverse Lanes Reverse Lane Public Hearing Sunnyslope Community Center October 6, 2010 Kerry Wilcoxon, P.E. Reverse Lane Public Hearing Sunnyslope Community Center October 6, 2010 Kerry Wilcoxon, P.E. OverviewOverview Operational AnalysisOperational Analysis Public OpinionPublic Opinion

2 City of Phoenix Street Transportation Department 2 Reverse Lane Overview Reverse Lane Study  Technical Analysis by Street Transportation Current studies  Quality-of-life analysis by ASU PURL Including differences among neighborhoods Operational Alternatives

3 City of Phoenix Street Transportation Department 3 Background Mayor Hance identified traffic congestion as #1 concern for Phoenicians in 1979 Mayor/Council directed staff to develop low-cost solutions Widening or building new streets was not an option Reverse lane selected to accommodate growth in Central Core

4 City of Phoenix Street Transportation Department 4 7 th Street started in 1982  Adams to Dunlap Ave  Now McDowell to Dunlap (7 miles) 7 th Avenue & 7 th Street Central Phoenix 7 th Avenue started in 1979  McDowell to Northern Ave. (6 miles)

5 City of Phoenix Street Transportation Department 5 7TH AVE7TH ST Without Reverse Lanes 3 Lanes NB each street 650 Vehicles/Hour/Lane Without Reverse Lanes 2 Lanes SB each street 650 Vehicles/Hour/Lane

6 City of Phoenix Street Transportation Department 6 7TH AVE7TH ST With Reverse Lanes 4 Lanes NB 33% Capacity Increase 750 Vehicles/Hour/Lane With Reverse Lanes 3 Lanes SB 50% Capacity Increase 750 Vehicles/Hour/Lane

7 City of Phoenix Street Transportation Department 7 Original Issues Dilemma:  Benefit – Increased north/south traffic flow  Detriment – Limited turning movements Concerns:  Neighborhood cut-through  Safety  Access (to businesses and neighborhoods) Questions: Are they still needed? If yes, can they work better? If no, what are the consequences (costs) of removal?

8 City of Phoenix Street Transportation Department 8 Study Approach Engineering  Street Transportation Department Review current conditions Forecast future demand Public Perception  Phoenix Urban Research Lab (PURL) ASU Survey stakeholders

9 City of Phoenix Street Transportation Department 9 Street Transportation Dept Crash Rates  Comparison – 7 th Ave to 19 th Ave 7 th St to 16 th St Lane Utilization  Percentage of reverse lane utilization  Traffic speeds Capacity Analyses  Traffic flow modeling

10 City of Phoenix Street Transportation Department 10 Crash Rate Comparison Methodology  Study Period 2003-2005 (pre-LRT)  Streets Examined - 19 th Ave, 7 th Ave, 7 th St, 16 th St  Crashes involving at least one north/south vehicle Calculation Crash Rate = Crashes by Hours Hourly Traffic Volumes x Length

28 City of Phoenix Street Transportation Department 28 Neighborhood Cut Thru Analysis North Current: Left-turn generated cut-thru Cause: Left-turn restrictions at signals Occurs: Downstream of signals Primarily left turns into neighborhoods Predicted: Congestion generated cut-thru Cause: Low capacity at signals Occurs: Upstream and downstream of signals Includes left and right turns into neighborhoods

30 City of Phoenix Street Transportation Department 30 Traffic Counts During Recession 14% reduction in Average Daily Traffic (ADT) at city-wide count stations from 2005 to 2009 30% reduction in ADT on the reverse lane streets from 2005 to 2009

31 City of Phoenix Street Transportation Department 31 Engineering Findings Traffic safety on 7th Avenue and 7th Street similar to other arterial streets Reverse lanes carry a substantial amount of rush hour trafficReverse lanes carry a substantial amount of rush hour traffic Removal would result in loss of capacity with same demandRemoval would result in loss of capacity with same demand Neighborhood cut-thru routes may shiftNeighborhood cut-thru routes may shift

32 City of Phoenix Street Transportation Department 32 ASU Phoenix Urban Research Lab (PURL) – Stakeholder Survey Goal: Determine how stakeholders view the lanes and how they would change them (improve, eliminate, preserve)? Process Identify stakeholders (drivers, peds, bicyclists, residents, business owners, etc.) Conduct sample-based surveys of stakeholders Conduct focus groups of stakeholder groups Analyze survey and focus group responses

33 City of Phoenix Street Transportation Department 33 Very few satisfied with business-as-usual  Main quality-of-life concerns: Reverse lanes inhibit access Most feel lanes are unsafe Driver confusion  Would recommend: Keep the lanes & add electronic signage Eliminate the reverse lane on 7th Street/7th Avenue Little support to keep lanes with no changes Quality-of-Life Study Results Central Phoenix Neighborhoods

34 City of Phoenix Street Transportation Department 34 Quality-of-Life Study Results North Central Neighborhoods More satisfied with operation than other stakeholders  More than 50% say: Lanes are safe and reduce travel time Reverse lane signs are understandable  Would recommend: Enforcement and more left turn opportunities Sign upgrades e.g., electronic signs
