Data Collection & Analysis • JAMAR Traffic Counter • Synchro 6
Level of Service Criteria – Signalized Intersections (TRB, HCM2000)
Proposed Improvements • Increase lane width Increase lane width on minor St. from 10’ -> 12’ (insignificant) • Right turn channelization Introduce channelized right turns with yield control on minor St. (LOS: E->D) • Additional lanes Provide an additional travel lane to minor street. (LOS: E->D) • Signal Timing Optimization Use Synchro-suggested (62,64) phase than current (80,54) (LOSM: E->F;LOSm: F->D)
Conclusion • Improvement of this intersection is needed • More aspects should be considered (safety, cost)
