Technical > Projects > Arnhem-Nijmegen

The model area - covering almost 1000 km2 - is characterized by the cities of Arnhem in the north and Nijmegen in the south, the two rivers running between them and several important motorways connecting with southern, western and northern parts of the country plus Germany. The completed model of the current network contains some 1700 nodes, 4000 links, 270 zones and over 200 signalized intersections (see below).

At present the network is congested during daily peak periods, both on the motorways and within the two cities. This causes delays for commuters, trucks and buses. Economic growth and major house building projects are expected to increase traffic volumes, making congestion worse in the near future. The national government and provincial and municipal authorities are considering measures such as ramp-metering, exclusion of through-traffic from towns, improvements to intersections and traffic signals, extra lanes and dedicated bus lanes.

CONTRAM7 is being used to help evaluate existing plans for the area in relation to traffic conditions and public transport quality by simulating peak period traffic flows in 2010. This will also enable potential new bottlenecks to be identified and the effects of extra measures to be studied in detail. Full results are expected at the end of the year.
