Pomona Valley ITS

Information

Overview

Phase 1 of the Pomona Valley ITS Project was the conceptual design that determined solutions to transportation congestion problems in the Pomona Valley. This phase focused on solutions to daily congestion on freeways and arterials, traveler information, incident-related back-ups, and event management for the Fairplex and surrounding areas.

Phase 2 is the detailed design and system procurement phase of the Pomona Valley ITS Project. This phase centers on the design, integration, and testing of Advanced Traffic Management System (ATMS) deployments per the Pomona Valley ITS Conceptual Design that was completed during Phase 1.

The PVITS project has three primary project components. ITS technologies will be developed related to:

Pomona Valley Forum-Wide ATMS

The Forum-Wide Advanced Traffic Management System (ATMS) is intended to build upon the benefits achieved by the existing time-based signal synchronization projects implemented by the County. When installed, the ATMS will allow for two-way communications, real-time database management, and control and monitoring functions between the traffic signal controllers and each affected agency.

The Conceptual Design Master Plan will include infrastructure requirements and conceptual design of the following:

An interface and link with the proposed Los Angeles County TMC and other proposed sub-regional TMCs to be located in the other Los Angeles County Traffic Forum areas.

A sub-regional TMC in the City of Pomona;

Monitoring/control workstations located in the existing facilities of each municipality located in the Pomona Valley Traffic Forum and Route 60 Corridor area;

Data and video links to the State of California Department of Transportation’s (Caltrans’) District 7 and District 8 Traffic Operations Centers (TOC); and

Route 60 Corridor Conceptual ATMS

The Route 60 Corridor Conceptual Advanced Traffic Management System (ATMS) component will include the conceptual identification of pre-packaged and pre-timed scenario response plans that would require traffic control and monitoring systems, motorist information and accident/incident management. The conceptual design will be based upon a cooperative, multi-agency effort to optimize corridor-level traffic flows.

The Route 60 Corridor study area extends from SR 57 to the east to I-605 to the west. The first step in the conceptual design phase will be to define the study area in terms of which arterials should be analyzed for inclusion in the corridor. Generally those arterials and collectors that roughly parallel or provide access from the freeway to those parallel arterials would be studied to determine whether traffic utilizes those (or should utilize those) as alternative routes to State Route 60.

The design will be a guide for the development of tools to coordinate daily traffic control and traffic management activities. It may include a decision support system which will identify the software interfaces and protocols to intertie closed circuit television (CCTV) cameras, signal control, and changeable message signs (CMS) between Caltrans, the County, and other local agencies.

Fairplex Traffic Management Plan

The Los Angeles County Fairplex Traffic Management Plan will include a complete traffic study and the research and conceptual design of specific ATMS strategies. An ATIS component will also be included to improve the management and operation of traffic on public highways and parking lots surrounding the Fairplex for weekday and weekend special events. The ATIS technologies could include the installation of changeable message signs (CMS); Closed Circuit Television (CCTV); parking guidance systems; Highway Advisory Radio (HAR); Highway Advisory Telephone (HAT); and communication links to cable TV, travel and information channels, information kiosks, and private sector travel information services.
