Transportation Management System Replacement

Project Description

This project proposes to upgrade, install new, or replace existing inefficient and outdated Transportation Management System (TMS) elements and pave areas for Maintenance Vehicle Pullouts (MVPs) at various locations - in Merced County on Interstate 5 (I-5) and State Route 99, 140, 152, in Stanislaus County on State Route 99, in Tuolumne County on State Route 108, 120. There is a total of 23 locations.

The scope of this project consists of the following:

  • Replace 1 Changeable Message Sign (CMS)
  • Replace 7 Closed-Circuit Television (CCTV) cameras
  • Install 2 new Closed-Circuit Television (CCTV) cameras
  • Replace 9 Vehicle Detection Systems (VDS)
  • Install 2 new Vehicle Detection Systems (VDS)
  • Replace 1 Traffic Signal
  • Install new 1 IP camera
  • Replace 5 Roadside Weather Information Stations (RWIS)

The pavement work consists of construction of 9 MVPs. MBGR at various locations within the project limits will be upgraded to current standards.


Project Benefits


The purpose of this project is to install new TMS elements, or replace/upgrade existing outdated TMS elements, components, and/or equipment with more reliable and efficient technologies that are available, while meeting current Caltrans standards, and to provide safe maintenance vehicle access to those facilities.


In Merced, Stanislaus, and Tuolumne counties in various locations on State Routes (SR) 5, 99, 108, 120, 140, and 152, Transportation Management Systems (TMS) and their components/ equipment require either complete replacement, or the installation of new TMS elements. In some locations, the installation of new Maintenance Vehicle Pullouts (MVP) is needed. There is a need to improve operations, the mobility and safety of the traveling public by ensuring the Traffic Management Center (TMC) has reliable real-time live video feed of roadway, traffic, and weather conditions, and to provide the TMC with advanced warning of congestion or incidents within the project limits, in order to help ensure the appropriate deployment of emergency response resources. There is also a need to provide maintenance vehicle access to those facilities to improve the safety of both the traveling public and field employees by reducing the frequency of the latter's exposure to live traffic.
