Transportation and Traffic Improvement Post-mitigation Condition Signal plans are currently being reviewed by Cal- LS trans. In addition, widen the on-ramp to accept a double westbound left turn lane. About $14 million has been committed for interchange variA ous improvements by developers. Install new traffic signal (as recommended in the 1996 General Plan). Install new traffic signal (as recommended in the 1996 General Plan). See discussion be/ow. The General Plan exempts this intersection from the LOS D standard. The General Plan exempts this intersection from the LOS D standard. Upgrade signal to allow for a PM peak hour northbound/eastbound right turn overlap phase. Install new traffic signal (as recommended in the General Plan). Construct southbound right turn lane. Change the eastbound through-left turn lane into a sec- ond left turn lane and provide permissive phas- ing on the east and west approaches. Recon- struct the west median to provide a third east- bound left turn lane. Reconstruct east median to provide second westbound right turn lane. A developer recently upgraded the signal and striping to convert a northbound through lane into a third northbound left turn lane. This con. dition result has resulted in LOS D (36.3)/D (51.8). No further mitigation is needed. Convert a northbound through lane into a third northbound left turn lane (requires widening of West Las Positas or median reconstruction to receive 3 inbound lanes).
