As at the intersection of Hopyard Road at Owens Drive, the north pedestrian crossing area experiences the highest level of conflicts with through and turning vehicles. The westbound through traffic movement is relatively light, while the time it takes for a pedestrian to cross Hacienda Drive is very long. This disproportionately takes green time away from all of the other people trying to get through this busy intersection. The Year 2025 LOS calculations assume that the north crosswalk at this intersection is removed. This reduces congestion by allowing a shorter green light for westbound traffic, which in turn provides more green time for the heavier directions of travel. Hacienda Drive at West Las Positas Boulevard Mitigation - Upgrade traffic signal to unsplit north/south phasing. Modifying the traffic signal and striping at this intersection so that southbound Hacienda Drive and northbound driveway traffic move simultaneously, will significantly increase the amount of green time available for drivers along West Las Positas Boulevard, thus decreasing stops and delay at the intersection. Hopyard Road at Del Valle Parkway Mitigation - Construct new speed sensitive traffic signal In all Year 2025 scenarios, the flow of traffic along Hopyard Road exceeds the capacity of the stop sign controls at this intersection, resulting in LOS F conditions on Hopyard Road. Stop sign controls have far less capacity than traffic signal control. This was recently demonstrated at Vineyard Avenue at Montevino Drive where traffic backups were eliminated when the signal replaced the previous 4-way stop. A speed sensitive traffic signal would decrease traffic congestion at this intersection, while still controlling speeds along Division Street. The 1996 General Plan shows this intersection as a future traffic signal location. Hopyard Road at 1-580 Eastbound Off-ramp Mitigation - Minor traffic signal upgrade Upgrading the traffic signal to allow eastbound right turn off-ramp traffic to move concurrently with northbound through traffic for an adjustable period of time would make this signal more efficient and thus reduces delay significantly for local traffic. Hopyard Road at 1-580 Westbound Off-ramp Mitigation - Restripe off-ramp and minor traffic signal upgrade About 75% of traffic exiting the westbound 1-580 off-ramp turns right into Dublin. Modifying the off ramp striping and traffic signal to convert the #2 left tm'n lane into a left/right turn option lane would reduce congestion and delay at this intersection. Hopyard Road at Owens Drive Mitigation - Widen intersection to add an additional east and westbound lane. Narrowing the raised median and widening Owens Drive along the north side of the street would allow eastbound Owens Drive to be striped as a triple left and a through/right lane, and westbound Owens Drive with a left, left/through, and double right turn lanes. This would reduce overall delay at the intersection to LOS D, with some movements still experiencing LOS E and F conditions in the Year 2025.
