Interstate 205 Smart Corridor – Phase 2
Project Description
This project will add on to previous Intelligent Transportation System (ITS) projects, which installed vehicle detection and a communications infrastructure, and complete an instrumented corridor that can better manage traffic through the region. The primary focus of this project is to install ramp meters at on-ramps on Interstate 205 (I-205). Ramp meters will automatically control vehicle access onto the freeway system during peak times. By restricting vehicle demand, the onset of congestion on the mainline will be delayed and the overall level of congestion observed will be reduced.
Purpose and Need
The purpose of this project is to alleviate both recurring (AM and PM peak hour) and non-recurring congestion along I-205 in San Joaquin (SJ) County through the deployment of Intelligent Transportation Systems (ITS) elements. This project is needed to maximize mobility in this segment. Mobility benefits include reliable travel times with increased speed and improved corridor productivity, safety, and preservation. Implementation of this project may also improve air quality and reduce greenhouse gases in the SJ Valley.
Funding Source
The project is funded in the State Highway Operation and Protection Program (SHOPP), Traffic Operations Improvement Program.
