Staff members in each City have also received numerous inquiries relating to the activation of westbound I-580 ramp meters during the morning commute. Staff believes that westbound ramp metering will improve traffic flow on 1-580 and reduce regional cut- through traffic on local streets during the morning commute. As a result, Pleasanton, Livermore, and Dublin met with Caltrans and Metropolitan Transportation Commission personnel earlier this year to discuss potential morning ramp metering on westbound 1- 580. Staff and Caltrans personnel are currently collecting data in preparation of a before study. The study will quantify ramp metering impacts and improvements throughout the Tri-valley. In the upcoming months, Caltrans and staff from each city will develop ramp metering timing plans, install any additional ramp metering equipment, and turn on the ramp meters. Caltrans anticipates the ability to activate the westbound ramp meters in late 2008. Staff will have the opportunity to direct ramp metering signal timing changes. If staff or the City Council finds that one or more of the metered ramps results in unacceptable increases in traffic delays or congestion, Caltrans will - at the City's request -operate the specified onramp metering lights in constant green mode or at the demand rate during the time period necessary to eliminate the negative impact the metering light is having on the adjoining City roadway or intersection.
