Reducing Traffic Congestion with Real-time Traffic Condition & Performance Data

San Jose, CA, USA

At a Glance

The City of San José is pursuing a semi-customized software tool that will provide real time traffic condition and system performance data to staff at its Transportation Incident Management Center (TiMC) to help mitigate traffic congestion and delays.

Problem Addressed

San José's Transportation Incident Management Center (TiMC) enhances the city's ability to manage its transportation facilities by integrating arterial and freeway management services across Santa Clara County. Staff currently conducts traffic incident management by individually reviewing data from a patchwork of information systems and data sources, including but not limited to the Google traffic congestion map, the Department of Public Works’ Cone Zone map, the Metropolitan Commissions Transportation System’s 511 System, the City’s traffic video cameras, and service requests from the public. These data sources provide information on events and activities that impact traffic congestion - such as vehicle incidents, construction activities, planned events, freeway congestion, and traffic signal malfunctions - but the analysis must be done individually. The City requires a way to comprehensively analyze and integrate data from many different sources and allows staff to input and track real-time events

City of San José used/is using /is using an event tracking system to address this/these challenge(s).

Solution(s) Used

The City is enhancing the TiMC’s traffic management capabilities by deploying an information system that integrates the information from various data sources and allows staff to input and track real-time events in a comprehensive TiMC Event Tracking (eTracker) System. The System will alert staff to: 1. Degrading traffic flow conditions resulting from unplanned events, unusual congestion zones, and other incidents, 2. Adjust traffic signal timing to optimize traffic flow conditions for scheduled events and construction activities to support additional travel demands, lane reductions and/or diversions, 3. Review roadway performance history for traffic signal retiming update needs assessment, 4. Initiate timely repair of traffic signal facilities.

Outcomes

  1. Will direct staff to use available real time traffic congestion data from additional third party providers to stay attuned to traffic conditions.
  2. Will help prioritize maintenance efforts on the roadways that need immediate attention.
  3. Will assist coordination of traffic management services with other agencies and departments to minimize congestion and travel delay.
  4. Will reduce travel demand & encourage the use of alternative modes of travel.

Something Unique

This project is one of 21 priority projects on the Civic Innovation Roadmap focused on using technology and real time data to improve core service delivery, staff capacity, and roadway conditions!
