Siemens ACS Lite .
The Federal Highway Administration awarded Siemens a competitive, two-year contract to enhance its Adaptive Control Software Lite (ACS Lite) software.
ACS Lite was designed to provide a relatively low cost and easy-to-use adaptive traffic signal control system, targeted as an upgrade to existing closed-loop signal systems. ACS Lite monitors traffic flow at and between intersections and calculates beneficial adjustments to the signal timing every five to 10 minutes.
Despite already being a street-ready technology that provides significant benefits there remains ample opportunity to improve the performance of ACS Lite. Under the newly awarded contract, which will span from 2008 to 2010, ACS Lite will be enhanced to adjust cycle lengths longer or shorter for increasing or decreasing traffic congestion and to provide more advanced handling of vehicle detector failure scenarios.
This can provide significant benefits as traffic flow changes in the short-term (e.g., due to diversion around an accident, construction, or flooded area) and in the long term (e.g., as commercial and residential development permanently affect traffic flows).
The resulting system was independently evaluated in the lab (using traffic simulation software) and in the street (at four cities across the nation) and shown to provide signficant benefits. On an arterial in Houston, Texas, it was found that ACS Lite reduced vehicle delay by 35%, vehicle stops by 29%, arterial travel times by 11% and fuel consumption by 7%.
