ACS Lite - Mobility USA. Overview ACS Lite is an adaptive control software application that has been developed as a closed-loop system by Siemens under contract to the FHWA Research, Development and Technology Traffic Operations Program.
It may be deployed as an on-street field master or on a central server. The ACS Lite software is designed to adapt the splits and offsets of signal control patterns/plans in a “closed-loop” system. Changes to cycle time are handled on a time-of-day schedule like traditional traffic control systems. At each optimization step, which occurs about every 10 minutes, the system changes the splits and offsets a small amount (e.g. 2-5 seconds) to accommodate changes in traffic flows.
Headline Story. Intelligent Transportation Systems (ITS) SACOG is working with local partners to plan and implement Intelligent Transportation Systems (ITS) projects to improve traffic flow and reduce vehicle emissions.
ITS projects use advanced technology and tools such as freeway ramp meters, dynamic message signs and traffic signal timing to provide real-time information on traffic conditions and coordinate operations at local traffic centers. The Sacramento Transportation Area Network, or STARNET, is a major component of the Sacramento region's ITS architecture. While ITS technologies can be found throughout the region, several collaborative efforts are underway to address the most congested corridors. Intelligent transportation system « Technology New Here : New Technology Systems. Intelligent transportation systems are projects that aim to integrate modern communication and information technology into existing transportation management systems in order to optimize vehicle life, fuel efficiency, safety, and traffic in urbanized cities.
The need for intelligent transportation systems stems from the fact that traffic congestion has been increasing all around the world because of increasing population, increasing amount of transportation vehicles and increasing urbanization. Wireless Technologies Wireless communication technologies have been proposed, tested and used for intelligent transportation systems. From the short-range communications systems like WAVE or IEEE 802.11 protocol to the range extended by utilizing mesh networking or mobile ad hoc networks, many possibilities exist.
