BACKGROUND In January 1983 Caltrans and the City of Pleasanton adopted an agreement for the construction, operation and maintenance of traffic signals at the I-580/Hopyard Road interchange. The agreement realized the need to maximize traffic signal efficiency along Hopyard Road (Pleasanton) and Dougherty Road (Dublin). Caltrans agreed that Pleasanton should operate and maintain both traffic signals. In 1990 the City and Caltrans updated this agreement to include the following: • Pleasanton will operate and maintain traffic signals at locations where arterials intersect with Caltrans facilities (1-580 and 1-680). • Caltrans will reserve the option to check at random all areas maintained by the City to assure conformance and terminate the agreement if the City failed to maintain acceptable maintenance levels. This includes traffic signal timing. • The City and Caltrans will share routine operations and maintenance costs. • Any improvements or modifications will be paid for by the City unless agreed upon by Caltrans. The 1-680/Stoneridge Drive and I-580/Hopyard Road traffic signals were included in the agreement. Subsequent amendments by the City and Caltrans added 1-580 interchange traffic signals at Hacienda Drive and Santa Rita Road/Tassajara Road. In 2000 and 2008 the City constructed traffic signals at the I-680/Bernal Avenue interchange for the northbound and southbound ramps, respectively, but was unable to amend the agreement to include these locations. As a result, Caltrans currently operates and maintains these two traffic signals. This limits the City's ability to develop and implement traffic signal timing, improve corridor operations and effectively respond to nearby special events, equipment failures or emergencies. DISCUSSION The Bernal Avenue corridor is one of the most heavily traveled arterials in Pleasanton, carrying approximately 26,500 vehicles per day. Nearby residential, commercial and retail land uses also generate significant morning and afternoon peak hour traffic. Improving signal timing along the corridor during these peak times will help reduce average delays and greenhouse gas emissions. With a mix of City and Caltrans owned traffic signals along this portion of Bernal Avenue, the City cannot implement corridor traffic signal timing improvements. By assuming operation and maintenance responsibilities for these two traffic signals, the City can implement signal timing designed to improve traffic operations along the Bernal corridor. The signals will also be integrated into the City's state-of-the-art Traffic Operations Center, which allows staff to implement signal timing improvements and monitor traffic conditions in real time. The Alameda County Fairgrounds are located on the northeast corner of Bernal Avenue and Valley Avenue. The Fairgrounds host a variety of special events, including the Alameda County Fair, the Goodguys car shows, and a myriad of other events that generate heavy and unpredictable traffic demand.
