Evacuation Planning - Hurricanes are a potential problem for Maryland’s eastern shore, because of the need to evacuate large populations of residents and tourists using a few routes with limited capacity. Working through the CATT, Civil Engineering Department faculty have developed an advanced traffic operations tool that can be used to effectively manage the evacuation in real-time, by monitoring traffic flow, estimating changes in demand, and examining the impact of alternate strategies. Potential strategies include traffic signal retiming, diversion and information dissemination. The tool permits the user to enter alternative strategies, and evaluate their impact using an integrated set of applications including simulation, displays of traffic conditions, and other forms of visualization that permit rapid comprehensive of system status.

HighwayServicePatrols The I-95 Corridor Coalition is an alliance of transportation agencies, toll authorities, and related organizations, including law enforcement, from the State of Maine to the State of Florida, with affiliate members in Canada. The Coalition provides a forum for key decision and policy makers to address transportation management and operations issues of common interest. This volunteer, consensus-driven organization enables its myriad state, local and regional member agencies to work together to improve transportation system performance far more than they could working individually. The Coalition has successfully served as a model for multi-state/jurisdictional interagency cooperation and coordination for over a decade. For more information on the 1-95 Corridor Coalition, visit their website.

I-95 Corridor Coalition Vehicle Probe Project - Vehicle probe technology is emerging as a means of monitoring traffic without the need for deploying and maintaining equipment in the right-of-way. In contrast to speed sensors, vehicle probes directly measure travel time using data from a portion of the vehicle stream. Commercial vehicle probe data services primarily include the use of cell phones and automated vehicle location (AVL) data. Early demonstrations of such systems relied heavily on a single method or technology. However, services are emerging that combine information from multiple probe sources and technologies, as well as data from existing fixed-sensor networks into a comprehensive traffic information service...More

LTAP The Local Technical Assistance Program (LTAP), jointly funded through the Federal Highway Administration (FHWA) and the Maryland State Highway Administration (Maryland SHA), provides transportation technology transfer services to agencies concerned with highways in rural and in urbanized areas with a population under one million. The LTAP mission is to stimulate active, progressive, and cost effective transfer of bridge/highway technology and to provide technical assistance to local and urban governments. LTAP accomplishes its mission through a network of LTAP centers (one in each State, one in Puerto Rico, and six that serve Native American Tribal Governments). Each LTAP center maintains mailing lists, publishes a quarterly newsletter and serves as a clearinghouse for transportation information. Also, all LTAP Centers exchange and publish information in a web clearinghouse called LTAP Clearinghouse. For more information about LTAP visit their website.

Maryland Statewide ITS Architecture - The Maryland Statewide ITS Architecture has been completed and is available on the ITS Maryland website. The Architecture documentation available on the website represents the first published Statewide Intelligent Transportation Systems (ITS) Architecture for the State of Maryland. It identifies existing and planned ITS projects across the state and the Architecture "Elements" associated with those projects. It also defines the relationships among the Elements and describes the flow of information between Elements. The Center for Advanced Transportation Technology has been providing technical assistance and project management support for this initiative.


MATOC - Transportation officials in the Washington area are working on an initiative called MATOC to address a mutually agreed upon need for managing transportation incidents and emergencies from a regional perspective by reacting cooperatively and effectively to incidents whose effects cross state boundaries, such as major crashes, extended lane closures, transit station closures, hazmat spills, or severe weather. The MATOC vision encompasses a number of identified core capabilities in the areas institutional coordination, system coordination, operational coordination, and public outreach coordination. The Center for Advanced Transportation Technology has been involved in the formative stages of MATOC and has received a $1 million grant under the Department of Homeland Security’s Urban Area Security Initiative to support MATOC implementation.

Performance Measures for Mobility - Federal, state and local government agencies are recognizing the importance of performance measures, and using these measures both to evaluate their service delivery, and to communicate more effectively to managers, political leaders and the public. The transportation community is no exception. In recognition of the importance of performance measurement for transportation operations, the American Association of State Highway and Transportation Officials (AASHTO) and the National Transportation Operations Coalition (NTOC) initiated a project for the development of a standardized set of performance measures to be made available to state and local transportation agencies. The work on this project was performed jointly by the University of Maryland and the International City/County Management Association (ICMA). The result of this work was the selection and definition of eleven performance measures to be used for the evaluation of transportation mobility on the nation’s highway system. These measures are intended to serve the purposes of both internal management and external communication. They were developed for evaluation of arterial performance, freeway performance and system-wide performance of the transportation system.


Performance Measures for Statewide Congestion - The Maryland State Highway Administration has a requirement for the evaluation of system congestion on a statewide basis. The information produced by this evaluation will be used to communicate with legislators and the public regarding the return received on their highway investment. The application of statewide measures is a particularly challenging task because of the variety of roadways and traffic conditions encountered in a wide geographic area. In addition, it will be important to present the information resulting from the evaluation in a way that can be readily understood by individuals who do not have an engineering background.


Real-Time Regional Traffic and Incident Data Feeds - As part of the RITIS project, the CATT Lab will be taking all traffic data from participating agencies and making it comply with the Traffic Management Data Dictionary. The lab will then make this data available via XML, JMS, FTP, RSS, and other methods to both public and private sector users. estimation, travel time prediction, traffic mapping and visualization applications, wireless applications, research, and planning.


Real-Time RSS Traffic Feeds - This research takes live traffic and incident data from the RITIS databases and creates an RSS traffic feed that can be subscribed to and viewed by the public. RSS stands for “Really Simple Syndicate” and is often used by the news media to provide important news updates. This service will be available to those with internet computer access, mobile phones, and Internet-enabled PDAs or Blackberries.

The goal is enter into a dialogue that enhances existing coordination, cooperation, and communication amongst participating agencies. The Forums are targeted towards dispatchers/operators and/or their first-level supervisors. The Center for Advanced Transportation Technology has been providing project management support for this initiative.


Traffic Signal Timing for Urban Evacuation - Working for the Federal Highway Administration (FHWA) CATT and Civil Engineering faculty conducted a research study intended to identify the most effective signal timing procedures to be used during a major “no-notice” evacuation. Using a corridor in Washington, DC, a number of evacuation scenarios were studied under conditions that ranged from a full-scale evacuation of the City, to more limited cases. The study examined evacuation times for various signal timing strategies including flash and the use of very long cycle lengths. Its conclusions are of value to system operators throughout the United States.
