EM04-Roadway Service Patrols (Service Package*)

Description

This service package supports roadway service patrol vehicles that monitor roads that aid motorists, offering rapid response to minor incidents (flat tire, accidents, out of gas) to minimize disruption to the traffic stream. If problems are detected, the roadway service patrol vehicles will provide assistance to the motorist (e.g., push a vehicle to the shoulder or median). The service package monitors service patrol vehicle locations and supports vehicle dispatch to identified incident locations. Incident information collected by the service patrol is shared with traffic, maintenance and construction, and traveler information systems.

Associated Objectives and Performance Measures

Objective Performance Measure
Increase customer satisfaction with the region's incident management by X percent over Y years. Percentage of customers satisfied with region's incident management practices.
Increase the number of corridors in the region covered by regional coordinated incident response teams by X percent in Y years. Number of TIM corridors in the region covered by regional coordinated incident response teams.
Reduce buffer index on arterials during peak and off-peak periods by X percent in Y years. The buffer index (represents the extra time (buffer) travelers add to their average travel time when planning trips in order to arrive on-time 95 percent of the time).
Reduce delay associated with incidents on arterials by X percent by year Y. Hours of delay associated with incidents.
Reduce mean incident clearance time per incident by X percent over Y years. (Defined as the time between awareness of an incident and the time the last responder has left the scene.) Mean incident clearance time per incident.
Reduce mean incident notification time (defined as the time between the first agency's awareness of an incident and the time to notify needed response agencies) by X percent over Y years (i.e., through "Motorist Assist" roving patrol programs, reduction of inaccurate verifications, etc.). Average incident notification time of necessary response agencies.
Reduce mean roadway clearance time per incident by X percent over Y years. (Defined as the time between awareness of an incident and restoration of lanes to full operational status.) Mean roadway clearance time per incident.
Reduce mean time for needed responders to arrive on-scene after notification by X percent over Y years. Mean time for needed responders to arrive on-scene after notification.
Reduce mean time of incident duration (from awareness of incident to resumed traffic flow) on transit services and arterial and expressway facilities by X percent in Y years. Mean time of incident duration.
Reduce the annual monetary cost of congestion per capita for the next X years. Cost (in dollars) of congestion or delay per capita.
Reduce the person hours (or vehicle hours) of total delay associated with traffic incidents by X percent over Y years. Person hours (or vehicle hours) of delay associated with traffic incidents.

 
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 Emergency Vehicle (i.e., the service patrol vehicle) determines its location (position fix) and reports its position and status to the Emergency Management dispatch function (emergency vehicle tracking data). Service patrol vehicle location and status is reported to the Emergency System Operator (emergency operations status). When necessary, the Emergency System Operator can enter commands (emergency operations inputs) that result in emergency dispatch requests to the service patrol vehicle. The dispatched vehicle can acknowledge the dispatch request (emergency dispatch response).

  2. At the scene of an incident, the service patrol vehicle can report the incident status to the Emergency Management dispatch function, which can relay the status as incident information to Traffic Management (e.g. reporting the severity and estimated duration of an incident), Information Service Providers (e.g. to report the incident information to their clients) and Maintenance and Construction Management (e.g. for incident cleanup) as appropriate.
