City of San Rafael, Department of Public Works 111 Morphew Street P.O. Box 151560 San Rafael, CA 94915-1560 Dear Ms. Blomquist: Subject: Grand Avenue Pedestrian Bridge Traffic Engineering Services To enhance the safety of pedestrians and bicyclists at the intersection of Grand Avenue and Second Street and to fully study the safety improvements related to the relocated driveway on the southeast corner of the intersection Siegfried would like to present the traffic signal modification and study scope of work below. Said scope of work if approved will be integrated into the existing project schedule and will become an integral part of the plan set, specifications, and project estimates. In general the proposed traffic signal modifications would upgrade the existing traffic signal with mast arms and signal heads, and will install audible countdown pedestrian signals. The traffic signal modification design will conform to the City's standard design and California MUTCD guidelines, and Caltrans standard plans, specifications and design requirements. The specific deficiencies that will be resolved are: • The existing traffic signal does not have pedestrian signals or push buttons. • The existing traffic signal operates on fixed time which is not optimal for pedestrian, bike, and traffic flow. • The existing traffic signal timing is for pedestrian timing minimum for the vehicle timing. Pedestrian timing occurs for every cycle regardless if pedestrians are present. This is not optimal for pedestrian and bicycle and vehicle flow. Scope of Work Task 1: Traffic Analysis The design team will provide traffic operations analysis for the proposed driveway impacts on 2nd Street at Grand Avenue. Based on our initial field review of the project site and knowledge of the area, we will carry out the following tasks: • We will complete turning movement traffic counts for the intersection for the am peak hour and the pm peak hour from lam to 9am and from 4pm to 6pm. • We will coordinate with the civil design layout of the site to evaluate the best location for the new driveway location.
