Enabling microscopic traffic simulation with detailed driver behaviour on road-networks


TNO Inro, Delft, The Netherlands


Three different levels of detail exists for traffic-modeling; macroscopic, mesoscopic and microscopic. The department Traffic and Transport, TNO Inro, uses primarily microscopic travel simulation models. Microscopic traffic simulation models are based on a very detailed representation of the real world. It not only keeps track of the state of each vehicle, its behavior is individually determined by the model. Its speed and takeover behavior is a result of factors like road-type, speed of the predecessor and possibly even traffic information from the side of the road.

Within TNO the need exists to simulate traffic on a microscopic level in a road-network. They want to analyze the impact on the traffic of recent driver assisting systems as ISA (Intelligent Speed Adaptation), ACC (Adaptive Cruise Control) and Lane Departure Warning. One of the programs currently used by TNO to analyze traffic, Quadstone’s Paramics, is capable of modeling traffic on network roads, but the driver-model is not detailed enough for the applications mentioned above. Besides Paramics, TNO developed and implemented its own traffic simulation model. This model does contain a detailed driver and vehicle model, but it is only designed and implemented for straight piece of (high)way.

The objective of this assignment is to define a traffic simulation model, capable of detailed driver and vehicle behavior as well as modeling traffic on complex road-networks.

By making a detailed description of the current MIXIC model, it can be compared with the model used within Paramics. The result of this research combined with knowledge from literature forms the model. This model will be implemented so it can be used within Paramics.
