APTS02-Transit Fixed-Route Operations (Service Package*)

Description

This service package performs automated dispatch and system monitoring for fixed-route and flexible-route transit services. This service performs scheduling activities including the creation of schedules, blocks and runs, as well as operator assignment. This service determines the transit vehicle trip performance against the schedule using AVL data and provides information displays at the Transit Management Subsystem. Static and real time transit data is exchanged with Information Service Providers where it is integrated with that from other transportation modes (e.g. rail, ferry, air) to provide the public with integrated and personalized dynamic schedules.

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. In order to assess the impact on its operations, the Transit Management Subsystem (TRMS) collects data on the transportation network used by its fleet of transit vehicles. This data includes current traffic video images, current and forecasted traffic information, road and weather conditions, and incident information obtained from the Traffic Management Subsystem (traffic images, road network conditions and incident information). The data also includes current asset restrictions (e.g., width, height and weight restrictions), roadway maintenance status (e.g. a summary of maintenance activities in the area relevant to the transit fleet), and work zone information (e.g., work zone activities affecting the road network including the nature of the maintenance or construction activity, location, impact to the roadway, expected time(s) and duration of impact, anticipated delays, alternate routes, and suggested speed limits) from the Maintenance and Construction Management Subsystem. Upon request (archived data product requests) an Archived Data Management Subsystem (ADMS) can provide TRMS with archived data products that contain historical data used to assist with the planning portion of a transit management operation.

  2. One of the key functions of the fixed route operations is to assess the performance of the fleet vehicles and provide corrective actions if needed. The Transit Vehicle Operator can provide an input on the vehicle’s schedule status (transit vehicle operator inputs). This plus anticipated schedule deviations and estimated arrival information is passed from the Transit Vehicle Subsystem (TRVS) to the TRMS (transit vehicle schedule performance). This information is provided to the Transit Operations Personnel (transit operations status), who can create corrective actions (transit operations personnel inputs). This information is sent to the TRVS (transit vehicle operator information), and then presented to the Transit Vehicle Operator (transit vehicle operator display). An alternate operational concept is to use the information flows of APTS01 Transit Vehicle Tracking to identify at the TRMS the location and schedule performance of the vehicle.

  3. Another function of the fixed route transit operations is to assign transit vehicle operators to routes. To initiate this activity, the Transit Vehicle Operator provides their availability to the TRMS (transit vehicle operator availability). This information is passed to the Transit Operations Personnel (transit operations status), who inputs vehicle operator assignments (transit operations personnel inputs). The assignment information is provided to the Transit Vehicle Operator as a route assignment.

  4. The TRMS manages the fixed route fleet, and its real time knowledge of the fleet status is a valuable source of information for travelers. The TRMS provides the information as transit and fare schedules, transit schedule adherence information, and transit schedule information.
