CHARTiii
Formed to manage increasing traffic to and from
the Maryland shore, the Coordinated Highways Action Response Team (CHART) built on its initial success and is now a multijurisdictional and multidisciplinary program. The mission of CHART is to “improve real-time operations of Maryland’s highway system through teamwork and technology.” CHART relies on a communications infrastructure, a closed-circuit television system for traffic monitoring, and complex interfaces to existing and new detection systems to support the 24/7 monitoring and control activities of its Statewide Operations Center (SOC) and Traffic Operations Centers (TOCs). CHART uses the information collected in these centers to provide motorists with information through variable message signs, traveler advisory radio transmitters, and the highway advisory telephone system. CHART plans eventually to add a media interface to the SOC to allow the media access to high-quality, real-time traffic video. CHART also takes part in the I-95 Corridor Coalition to coordinate with other relevant agencies in case of regional incidents along the I-95 corridor.
 Structure
- Agencies such as the Maryland State Highway Agency (MdSHA), Maryland State Police (MSP), and the Maryland Transportation Authority, along with other Federal, State, and local agencies cooperate to improve real-time operations of Maryland’s highway system.
- The members of CHART are committed to working together, as indicated by their mission statement.
Processes
- The CHART program includes activities such as traveler information, incident management, traffic monitoring, and traffic management. MdSHA cooperatively funds joint needs.
Products
- A concept of operations shapes interagency cooperation in information sharing and management of the Maryland highway system.
Resources
- Agreements between the CHART agencies provide the resources necessary to effectively manage the transportation system. For example, MdSHA funds necessary items for MSP in return for full-time MSP staff at SOC. Through agreements with the media, CHART receives real-time views of traffic incidents and delays from traffic helicopters owned by local stations in exchange for allowing the stations to patch into live closed-circuit television feeds from SOC.
- Agencies see a return on investment of their time and resources.
Performance
- The CHART system hub is SOC, supported by existing satellite TOCs, which provide Statewide coverage allowing information distribution based on geographical needs and operations management from several different locations.
- CHART plans to integrate all radio communications, local government communications, and traffic signal systems activities to improve their incident management capabilities.
