Example network for PrT assignment procedures

The effectiveness of PrT assignment procedures is illustrated in the example in Image 70. The example analyzes the relation between traffic zone "village A" and traffic zone "city X". The following assumptions apply:

  • Access and egress times are not considered, that is, they are set to 0 minutes.
  • Turn penalties are not considered.
  • Capacity and demand refer to one hour.
  • The traffic demand between A-Village and X-City is 2,000 car trips (car.fma matrix) during peak hour.
  • To explain simultaneous assignment of multiple demand matrices 200 additional HGV trips (hveh.fma matrix) are considered. One HGV corresponds to two car units.
  • On federal roads (link type 20) there is a speed limit of 80 km/h for HGVs.

The example network contains three routes which connect A-Village and X-City. The routes run via the following nodes:

  • Route 1: 10 – 11 – 41 – 40
  • Route 2: 10 – 11 – 20 – 21 – 30 – 31 – 40
  • Route 3: 10 – 12 – 21 – 30 – 31 – 40

Route 1 mainly uses country roads and is 26 km long. It is the shortest route. Route 2 is 30 km long. It is the fastest route because the federal road can be traversed at a speed of 100 km/h if there is free traffic flow.

Route 3 which is also 30 km long is an alternative route which only makes sense if the federal road is congested.
