A constraint language for the generation of traffic management responses.

Operators of Advanced Traffic Management Systems (ATMSs) must react to traffic incidents quickly. This paper discusses an automated method for determining how field equipment should be modified in reaction to a traffic incident. A specialized constraint language is used to represent the desired policy as a set of rules. This language allows policy to be dependent on geographical realities such as the position of equipment and the design of the roadway. Determining the appropriate response from these rules requires integration with a Geographic Information System (GIS) database, so the response will take into account the actual roadway features present at the site of the incident.
