Black is labeled for the Salt River and Western Canal VEHICULAR INFRASTRUCTURE Overview • • • • Assess existing conditions of arterial roadways Identify roadway deficiencies (Vehicular, Bicycles & Pedestrians) Provide proposed improvements Between 27th Ave & 48th St, South Mountain & Salt River • Roadways Running North-South • 27th Ave, 19th Ave, 7th Ave, Central Ave, 7th St, 16th St, 24th St • Roadways Running East-West • Broadway Rd, Southern Ave, Baseline Rd, Dobbins Rd Existing Conditions • Roadway Functional Classifications defined by City of Phoenix • Majority of Roadways defined as Arterials • 19th Ave, 7th St, & Baseline Rd defined as Major Arterials • Roadways range from 3 lane to 7 lane sections • 2015 Annual Average Weekday Traffic Volumes provided by MAG • Speed & Congestion Data provided by MAG LOS Planning Level LOS Analysis • Level of Service (LOS) is a qualitative measurement of a roadways quality of traffic service • LOS is based on ADT and MCDOT acceptable service volumes based on roadway functional classification • Based on 2015 MAG volumes all roadways operate at LOS C or better Description A free flow, with low volumes and high speeds B reasonably free flow, speeds beginning to be restricted by traffic conditions C stable flow zone, most drivers restricted in freedom to select their own speed D approaching unstable flow, drivers have little freedom to maneuver E unstable flow, may be short stoppages F forced or breakdown flow • Light Rail extension proposed along Central Ave to Baseline Rd • Requires transitioning Central Ave from 4/5 lanes to 2 lanes • Locally Preferred Alternative Report prepare in 2014 • Decrease in volumes along Central Ave • Increase in Transit use • Increase in volumes along 7th Ave & 7th St • Decrease in LOS along Central Ave, 7th Ave, & 7th St Light Rail Extension Addition of Bike Lanes Bike Lanes proposed • 19th Ave (Salt River to Dobbins Rd) • Currently existing bike lanes in portion of corridor • Requires removal of 1 vehicular lane • LOS expected to remain at LOS C or better • 16th St (Broadway Rd to Baseline Rd) • Requires removal of 1 vehicular lane • LOS expected to remain at LOS C or better • Dobbins Rd (27th Ave to Western Canal) • Roadway widening required, existing pavement in poor condition • Widening would not require removal of vehicular lanes • LOS expected to remain at LOS C or better Recommendations & Conclusions • Installing Bike Lanes • 19th Ave (Salt River to Dobbins Rd) • 16th St (Broadway Rd to Baseline Rd) • Dobbins Rd (27th Ave to Western Canal) • Roadway configurations that are median separated with breaks for left turns • Provides safer feel for bicyclists and pedestrians, encouraging these forms of travel • Feeling of tighter roadways contribute to reducing vehicular traffic speeds. • Trees, Allowing on street parking Recommendations & Conclusions Cont. • Additional pavement marking that brings attention to bike lanes • Green markings, Bike symbols. • Limiting driveway access points along roadways also • Reduces potential conflict points for bicyclists and pedestrians • National Association of City Transportation Officials (NACTO) Design Guides • Designing streets that promote safe multimodal forms of transportation • Street guidelines, Bike lane guidelines, Drainage guidelines Public Outreach & Stakeholder Involvement Social Equity and Sustainability • Diversity of stakeholder meetings? • Do the stakeholders along the planned light rail extension want it? • Gentrification? Low Income & Renting Recommendations • Diverse Public Meetings • Various times • Provide food • Neighborhood Survey • Transparency • Community Cooperative QUESTIONS References "Alternative Analysis South Central Corridor."
