MC08-Work Zone Management (Service Package*)

Description

This service package manages work zones, controlling traffic in areas of the roadway where maintenance, construction, and utility work activities are underway. Traffic conditions are monitored using CCTV cameras and controlled using dynamic message signs (DMS), Highway Advisory Radio (HAR), gates and barriers. Work zone information is coordinated with other groups (e.g., ISP, traffic management, other maintenance and construction centers). Work zone speeds and delays are provided to the motorist prior to the work zones. This service package provides control of field equipment in all maintenance and construction areas, including fixed, portable, and truck-mounted devices supporting both stationary and mobile work zones.

This is the extra time between the average travel time and near-worst case travel time (95th percentile). The buffer index is stated as a percentage of the average travel time. Average buffer index or buffer time can be calculated using miles traveled as a weighting factor. Buffer time = 95th percentile travel time (min) – average travel time (min).
Decrease the buffer index for (specific travel routes) by X percent over the next Y years. The buffer index represents the extra time (buffer) most travelers add to their average travel time when planning trips. This is the extra time between the average travel time and near-worst case travel time (95th percentile). The buffer index is stated as a percentage of the average travel time. Average buffer index or buffer time can be calculated using miles traveled as a weighting factor. Buffer time = 95th percentile travel time (min) – average travel time (min).

Transaction Set Diagram

Note that this transaction set diagram (TSD) is only 1 of the 2 TSDs and so only a portion of the numbered items below refer to the TSD.
MC08 transaction set diagrams: Part 1, Part 2,



The source graphic, a Windows Metafile (WMF), for the TSDs can be downloaded here: TSD Part 1, TSD Part 2,

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. Work zone status (work zone status) inputs start from the Maintenance and Construction Field Personnel, who enter the information into a system in the Maintenance and Construction Vehicle Subsystem, MCVS (maint and constr field personnel inputs). Then (work zone status) is forwarded to the Maintenance and Construction Management Subsystem (MCMS). The Maintenance and Construction Center Personnel add their inputs to this information (maint and constr center personnel inputs) and provide (work zone information) to the following centers and terminators:

    • Traffic Management

    • Transit Management

    • Emergency Management

    • Information Service Provider

    • Media

    • Other MCM (another maintenance or construction organization) - information is bidirectional on this interface with work zone information being provided to MCMS and sent from the MCMS.

    Maintenance and Construction Field Personnel can get information from their vehicle regarding traffic information, road restrictions, environmental information, decision support information, maintenance schedules, dispatch instructions, maintenance personnel assignments, vehicle maintenance information, work zone status information, and corrective actions. This information is available asynchronously (maint and constr field personnel information presentation).

  2. The MCMS can also control surveillance devices at the Roadway within a work zone, specifically CCTVs (video surveillance control) that send (traffic images) back to the MCMS.

  3. The MCMS can also control barrier systems at the Roadway within a work zone (barrier system control), which can send (barrier system status) back to the MCMS. In addition, the MCVS can provide control of barrier systems and receive status back from these systems.

  4. In addition to sending work zone information to other transportation centers, the MCMS or TMS provides information directly to Drivers affected by the work zone activity using (roadway information system data), which controls output to dynamic message signs or Highway Advisory Radio. The information is provided to the drivers as part of driver information. Additionally, the MCMS monitors the roadway information device to ensure its correct operation (roadway information system status).

  5. The roadway information devices may also be controlled (roadway information system data) and monitored (roadway information system status) by the Field Personnel inside the MCVS.

  6. Based upon inputs from the field, the MCMS may place a request to the Maintenance and Construction Administrative Systems (maint and constr administrative request) for administrative information or services. Requests include: requests to purchasing for equipment and consumables, resupply, and requests to human resources that manage training and special certification for field crews and other personnel. The Maintenance and Construction Administrative Systems responds with the information or status requested (maint and constr administrative information). This information is presented to the Maintenance and Construction Center Personnel (maint and constr operations information presentation). An additional administrative function the MCMS supports is to provide overall work performance information (maint and constr work performance) to the Maintenance and Construction Administrative Systems (MCAS) for contract administration.
