Active Traffic & Transit Demand Management (ATDM) promotes the active, real time management, control and influence of travel demand, traffic demand and travel flow.
Through the use of coordinated ITS technologies that monitor for and respond to congestion and delays, traffic flow is managed and traveler behavior is influenced in real-time to achieve operational objectives such as preventing or delaying breakdown conditions, improving safety, promoting sustainable travel modes, reducing emissions, or maximizing system efficiency.
ATDM provides the capability to monitor, control, and influence travel, traffic and facility demand of the entire transportation system and over a traveler's entire trip chain.
With new emerging technologies, older systems are being phased out and replaced with advanced systems that have become the basis of Active Traffic and Transit Management strategies and the leading technology in the integration of traffic and transit systems.
An example of this approach is Integrated Corridor Management (ICM). ICM development analyzes transportation information from a multi-model perspective, allowing where feasible technologies for traffic, transit, and other modes to work together in easing overall congestion.
Two elements must be in place before any Active Traffic and Transit Management system can be effective:
1) comprehensive and integrated electronic monitoring and control of major roadways via TMCs; and
2) traveler information systems.
TDM is a set of strategies that focuses on modifying travel behavior.
By encouraging travel on multimodal and high occupancy modes, as well as managing and reducing peak-hour congestion, TDM seeks to reduce the total number of automobile trips by directing attention to moving a higher volume of people and goods rather than vehicles.
TDM strategies are categorized into six groups:
- Parking Management;
- Bicycle and Pedestrian Enhancements;
- Transit Enhancements and Marketing;
- Vehicle Sharing;
- Paratransit Services; and
- Employer-Based Programs.
By implementing multiple strategies from the six categories, the NYMTC planning area could see an increase in commuter volume while at the same time experiencing a reduction in traffic congestion and air pollution.
Each of these strategies is discussed in Appendix 4 of the Plan, with examples of TDM strategies and methods currently underway or planned in the NYMTC region.
New York State's official traffic and travel information source provides real time information and other resources for traveler
511NY www.511ny.org provides information online by phone at 511 and via text and maps regarding current traffic and transit conditions, transit route trip planning and ride share services. 511NY also provides via additional links travel information related to specific modes of transportation, such as automobile, public transportation, bicycling and air travel.
In addition, many agencies provide road closure, service interruption, and construction information through their websites and through social media outlets like Facebook and Twitter.
511NY Rideshare is the most comprehensive source for rideshare services in the NYMTC region. Many TDM strategies are implemented through the efforts of this regional, multi-agency partnership that offers a suite of programs, services and information for commuters, travelers and employers.
