The City of Emeryville has developed a 40th Street Concept Plan to create bus-only lanes (one by converting the westbound mixed-flow lane to bus-only), a two-way bikeway on the north side of the street, bicycle-pedestrian intersection improvements, bus stop improvements including passenger boarding areas, and streetscaping with opportunities for green infrastructure (natural storm water treatment) and public art.
A traffic study estimates that these changes would reduce eastbound bus travel times by 1.5 minutes during the evening rush hour. They would increase westbound auto and truck travel times by 1.2 minutes during the evening rush hour and 1.0 minutes during the morning rush hour. The video below shows evening rush hour traffic on 40th Street with the project. It begins looking west from the 40th and Adeline Street intersection.
