  1. Zone To Zone

    We first explain the general concept of Zone to zone demand generation before we describe how to proceed with SUMOPy. Zone definition: Definition of Zones, in SUMO also called "Traffic Assignment Zones" (TAZ). A TAZ defines the area where participants depart (zone of origin) or arrive (zone of destination). A TAZ does typically contain ...

  2. Definition of Vehicles, Vehicle Types, and Routes

    Traffic assignment zones (TAZ)# It is also possible to let vehicles depart and arrive at traffic assignment zones (TAZ). This allows the departure and arrival edges to be selected from a predefined list of edges. Those edges are used which minimize the travel time from origin TAZ to destination TAZ.

  3. 13 Last Step of Four Step Modeling (Trip Assignment Models)

    The traffic assignment step, which is also called route assignment or route choice, simulates the choice of route selection from a set of alternatives between the origin and the destination zones (Levinson et al., 2014). The first three FSM steps determine the number of trips produced between each zone and the proportion completed by different ...

  5. Route assignment

    Route assignment, route choice, or traffic assignment concerns the selection of routes (alternatively called paths) between origins and destinations in transportation networks.It is the fourth step in the conventional transportation forecasting model, following trip generation, trip distribution, and mode choice.The zonal interchange analysis of trip distribution provides origin-destination ...

  9. A zone-based traffic assignment algorithm for scalable congestion

    A sample traffic assignment algorithm inspired by [1] is implemented in this work as a template for illustrating the scalability Z-BAR provides. Since Z-BAR's purpose is scalability as opposed to traffic assignment itself, any traffic congestion model which uses weighted edges will be compatible with Z-BAR.

    depart/arrival position. The map from traffic assignment zones into edges is to be given to application as one input. The resulting trips consist of a start and end road together with a departure time but no explicit route information. Routes are usually calculated by performing a traffic assignment employing a routing procedure such as shortest
