The potential of microscopic simulation in traffic safety and conflict studies
2001 (English)Report (Other (popular science, discussion, etc.))
Abstract [sv]

Microscopic traffic simulation has been successfully used in evaluation of

traffic efficiency and emissions, but not yet widely in studies of traffic

safety aspects. This paper will discuss the potential of traffic safety

simulation based on experiences from simulation studies in two research

laboratories that were using very different types of traffic simulators.

TRANSIMS (Transportation Analysis and Simulation System) is a high-speed

parallel micro simulator that allows simulation of large metropolitan areas

on microscopic level. It utilises synthetic populations to create the traffic

demand and cellular automata for high-speed parallel simulation of traffic

flows. HUTSIM is a very different kind of microscopic simulator. The

object-oriented HUTSIM model is built for very high precision simulation of

interactions between vehicles, pedestrians, traffic environment and traffic

control. Because the high fidelity of modelling requires lot of computing

power, very large networks cannot be simulated. The paper explains the

difficulties in introducing safety and behavioural aspects into existing

traffic simulation programs. The use of HUTSIM in conflict studies is

presented together with the development work carried out. TRANSIMS has been

used in the estimate of accidents in large networks and the paper presents

this work.
