  1. PROJECT TEAM Maren Fulton Nicolle Sheaves Daniel Skovron Mohammed Al Jamal Lukas Salo SW 4th and Lincoln Bicycle Lane Options

  2. Introduction

  3. The problem • I-405 off-ramp • SW 4th Avenue

  4. The problem • I-405 off-ramp • SW 4th Avenue

  5. High cost option • Extend bike lane to intersection • Redesign traffic signal to alternate I-405 traffic and SW 4th Ave traffic. Possible solutions • Low cost option: • Restripe to more clearly show bike lane • Add 20 MPH speed limit sign • Add other signage warning drivers of merging cyclists

  6. Synchro6 software was used to create a simulation for the proposed signal change analysis

  7. LOS A under current configuration analysis

  8. LOS C when staggered analysis

  9. Low cost option • Accident history • Visual observation of risk during peak flow • Physical limitations of intersection • Affect on LOS Our solution
