"TAPAS Cologne" Scenario

Availability

88x31.png

The data is available under the Creative Commons licence. You must tell where the data is from, it is not allowed to use it for commercial purposes, as soon as you use it we want to be informed about it (use the sumo-user mailing list).

Setting up such a large scenario is a lot of work and we can not do it by ourselves only. That's why we currently only offer a reduced data set, which contains routes between 6:00 and 8:00 am. If you are really interested in the complete data set, ask how to obtain it at the sumo-user mailing list.

About

Brief Description

The "TAPAS Cologne" simulation scenario describes the traffic within the city of Cologne, Germany for a whole day. It is based on the open road network database OpenStreetMap and a demand based on TAPAS, a system for simulation of mobility wishes of a synthetic population.

As is, TAPASCologne is only hardly usable. Work must be put into improving the network quality, as well as into verification of the process how routes were mapped on the OSM network and on the routes themselves. We hope to gain participants responsible for the works that must be done. A list of possible work packages is available.

Contents

The TAPASCologne scenario package includes:

  • Road networks imported from OSM
  • POIs and Polygons imported from OSM
  • The mapped trips for time between 6:00 and 8:00 (am)
  • The SUMO-configuration file

As OSM data contains information about streets, railways, ways for pedestrians only, etc, we decided to include the following network versions:

  • "passenger_*" which contains only roads passenger vehicles are allowed to use
  • "roadvehicles_*" which contains roads for road vehicles (those used by pedestrians, trains, and bicycles were removed)
  • "all_*" which contains all roads

The idea behind this is to have a fast road network ("passenger_*") for DUA computation and for scenarios which only consider passenger traffic retrieved by TAPAS. Then, in a second step, which is not yet started, additional traffic such as public transport or delivery vehicles may be added and used in combination with "roadvehicles_*" networks. "all_*" networks are meant to be used by people who want it all......

Each of the road networks is again available in two versions - one with internal lanes (default since version 0.10.1) and one without. Again, choosing the proper network is a matter of personal interest.

The supplied routes are given for the "passenger_*"-network. Though not tested, yet, we assume that they can not be used directly with other networks from the package. Still, computing correct routes should be possible by starting DUAROUTER with the appropriate network and --repair option.

The following images show the the scenario area with polygons and points of interest. Because we assume that the networks differ in size, for each network type (passenger, roadvehicles, all), a shape file is included.

Version 0.0.1 to version 0.0.2

Quality

In the current version, we even have not tested the data, completely. The assumptions made on the quality are shown below. We decided not to use a numeric ranking, because we do not have real world numbers for most of the issues. The rank tries to distinguish between "good" (arrow upwards, green) and "bad" (arrow downwards, red) influences on the overall simulation quality.

  • Level16px 00.gif Network Topology and Edge Parameter (from OSM)
    • Level16px +3.gif Completeness
      • Seems to be quite complete (including even minor roads) when compared to other (commercial or administral) road networks; still, there is no information about "black spots";
      • todo: build density plot comparing commercial and this network (legal?)
    • Level16px -3.gif Lane Number Information
      • The information about lane numbers is stored via types, mainly. For several roads, an explicite lane number is given
      • todo: evaluate how much information is given explicitely
      • todo: compare to images, write down lane number per street
    • Level16px -2.gif Maximum Speed Information
      • Again, mostly available via types, as for lane numbers; is assumed to be mismatching on some places
      • Where can one get better information from?
  • Level16px -2.gif Traffic Management Artifacts
    • Level16px -2.gif Traffic Light Positions
      • Given for some junctions (nodes); Still, there seem to be no information whether a node not marked as controlled is really uncontrolled
      • todo: Try to find further controlled junctions or improve guessing
    • Level16px -3.gif Traffic Light Programs
      • Ungiven
      • todo: Ask about the default cycle time (if there is one) in Cologne; apply at least this one to the generated tls logics
    • Level16px -1.gif Other Traffic Management Artifacts
      • completely ungiven

Summary: The TAPAS Cologne scenario is assumed to be one of the largest - if not THE largest - freely available traffic simulation data set. Regarding the scenario size, both the road network and the traffic demand are given in a good quality. Nonetheless, many important information is missing or wrong and much further effort is needed to make the scenario realistic and complete.
