MC05-Roadway Automated Treatment (Service Package*)

Description

This service package automatically treats a roadway section based on environmental or atmospheric conditions. Treatments include fog dispersion, anti-icing chemicals, etc. The service package includes the environmental sensors that detect adverse conditions, the automated treatment system itself, and driver information systems (e.g., dynamic message signs) that warn drivers when the treatment system is activated.

Since the mapping between objectives and service packages is not always straight-forward and often situation-dependent, these mappings should only be used as a starting point. Users should do their own analysis to identify the best service packages for their region.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.

  1. The Maintenance and Construction Center Personnel can initiate control of the automated roadway treatment system (maint and constr center personnel inputs) and send a control signal to the Roadway Subsystem (roadway treatment system control). They also monitor the status of the system (roadway treatment system status, maint and constr operations information presentation).

  2. The automated roadway treatment system may contain environmental sensors, or sensors at the Roadway that provides the environmental data (roadway equipment coordination) from Other Roadway to the Roadway Subsystem. In addition, the system could provide driver information to Drivers by including an electronic sign (such as a Dynamic Message Sign) or the system could interface with a separate device that performs this function (roadway equipment coordination).
