Maximizing ‘Bang for the Buck’ Through Engineering Subject – Improving Operational Efficiency of our Roadway NetworkSubject – Improving Operational Efficiency of our Roadway Network The Process – Traffic Signal SynchronizationThe Process – Traffic Signal Synchronization The Project – San Bernardino County Tier 3 and 4 Traffic Signal SystemThe Project – San Bernardino County Tier 3 and 4 Traffic Signal System

The Issue Currently there are more than 272,000 traffic signals in the USA – All need signal timing updates regularly – Los Angeles ranked no. 1 in America’s Most Congested Cities (source TTI): over 70 hours annual delay per traveler; 366,969 excess gallons of gas Delay, speed, fuel consumption and air pollution can be improved by:- – Synchronizing Traffic Signals – Providing traffic signal systems for agencies to monitor traffic operations Currently there are more than 272,000 traffic signals in the USA – All need signal timing updates regularly – Los Angeles ranked no. 1 in America’s Most Congested Cities (source TTI): over 70 hours annual delay per traveler; 366,969 excess gallons of gas Delay, speed, fuel consumption and air pollution can be improved by:- – Synchronizing Traffic Signals – Providing traffic signal systems for agencies to monitor traffic operations

The Process Synchronizing Traffic Signals – Allows maximum operational efficiency of existing roadways – Utilizes the existing roadway capacity most effectively – Reduces delay – Reduces stops – Improves speed – Reduces gas consumption – Reduces pollutant emissions – MORE COST EFFECTIVE THAN BUILDING NEW INFRASTRUCTURE!!

Tier 3 and 4 Project San Bernardino County Comprehensive Traffic Signal System Background – 15 agencies have different traffic signal systems – ‘Traditional’ signal interconnect are incomplete and expensive – Need to provide ‘cheap’ solution – 15 agencies have different traffic signal systems – ‘Traditional’ signal interconnect are incomplete and expensive – Need to provide ‘cheap’ solution Answer : WIRELESS COMMUNICATION

Wireless Communication Options

Summary of Technology Serial-Radios – Conform to existing communications infrastructure – Low bandwidth – Low maintenance and operations costs Serial Radio Example – Many Cities currently use serial radios, e.g. Encom Serial-Radios – Conform to existing communications infrastructure – Low bandwidth – Low maintenance and operations costs Serial Radio Example – Many Cities currently use serial radios, e.g. Encom

Summary of Technology IP-Radios –Ease of management and maintenance –High bandwidth (can support CCTV) –No polling rate issues –State-of-the-art technology IP-Radio Example – Many IP-Radios have proven to be reliable, e.g. Alvarion, Proxim, Motorola. IP-Radios –Ease of management and maintenance –High bandwidth (can support CCTV) –No polling rate issues –State-of-the-art technology IP-Radio Example – Many IP-Radios have proven to be reliable, e.g. Alvarion, Proxim, Motorola.

Summary of Technology Cellular Radio Modems – For trunk communications between master radio and TMC – For remote locations Serial / IP Platform – Several manufacturers support both platforms, e.g. Raven XT Cellular Radio Modems – For trunk communications between master radio and TMC – For remote locations Serial / IP Platform – Several manufacturers support both platforms, e.g. Raven XT

Ethernet versus Serial Communications Ethernet Technologies – Tremendous technological progress in the past 10 years – Many cities migrating from serial towards Ethernet – Can achieve higher bandwidth (and speed) – Can transmit video over radio Converting Serial to Ethernet – Need terminal servers at controllers – Need virtual communications ports at TMC, or – Upgrade traffic management systems software that supports Ethernet (e.g. QuicNet Pro, Centracs) Ethernet Technologies – Tremendous technological progress in the past 10 years – Many cities migrating from serial towards Ethernet – Can achieve higher bandwidth (and speed) – Can transmit video over radio Converting Serial to Ethernet – Need terminal servers at controllers – Need virtual communications ports at TMC, or – Upgrade traffic management systems software that supports Ethernet (e.g. QuicNet Pro, Centracs)
