San Joaquin County Changeable Message Signs Project
Project Description
The project proposes the following Intelligent Transportation System (ITS) elements in San Joaquin County at various locations on State Route (SR) 4 (PM T14.6 to 25.99), Interstate 5 (I-5) (PM R21.44 to 27.9), and SR 99 (PM 15.8 to 18.5):
- Install four permanent Changeable Message Signs (CMSs) with Maintenance Vehicle Pullouts (MVP), plus two additional MVPs (total 6)
- Install six Closed Circuit Television (CCTV) Cameras
- Install Roadside Weather Information System (RWIS)
- Install Vehicle Classification Stations (VCS)
- Replace Microwave Vehicle Detection (MVD) with Loop Detector systems, Single Mode Fiber Optic (SMFO) cables and Communication Conduits (CC)
The CMSs, CCTV cameras, RWIS and VCSs would be connected to the Caltrans Stockton Transportation Management Center (TMC). The TMC will monitor the State highway system and provide the current roadway and weather conditions, highway closures or delays due to adverse weather, highway construction, maintenance operations or accidents to the traveling public.
Project Benefits
Purpose
The purpose of this project is to expand and integrate the existing ITS infrastructure and to establish a communication network that is secure, low-maintenance, Caltrans owned, cost effective and capable of high bandwidth to transmit data between Stockton TMC servers and field elements. This integrated system would provide the traveling public with real-time roadway, traffic, and weather information, as well as alternative routes when applicable. This project would complete the fiber optic network loop for a state-of-the-art, independent fiber optic communication network in San Joaquin County.
Need
The need is to provide a fully integrated communication network to address inadequate ITS within San Joaquin County. This would provide a solid foundation for future expansion of the communication network to other counties and eventually to other Districts and jurisdictions for a truly integrated, transportation-related, and communication network.
