Bottlenecks in road networks due to incidents

A project has been started to investigate methods for determining bottlenecks in road networks due to incidents. Various methods are possible to estimate the cost in terms of delay and casualties caused by incidents. These methods all need reliable input. However, obtaining accurate and reliable data on incidents is cumbersome due to the irregular nature of incidents.

When the costs of bottlenecks have been determined, a ranked list of 'high risk' or of 'nonproductive' road sections is available. In order to optimize network performance the task of the road manager is to improve these bottlenecks. However, it is crucial to have a well founded method for estimating the cost when it comes to making investments dependent on this ranked list.

So, the aim of this project is to compare various methods for estimating the cost and working towards a practical and reliable method suitable for implementation by Rijkswaterstaat.
