What is good about analytical traffic modelling?

Busy Traffic

We have published a new report presenting a brief discussion of why traffic modellers use analytical models for traffic and transport planning, management, design and operations purposes. 

The applications include traffic impact analysis, roundabout geometric design, efficient operation of traffic signal control systems and development of balanced Movement and Place solutions.  Analytical models enhance the productivity of transport planners and traffic engineers by allowing them to analyse more scenarios with less effort.  They are also used for verification and calibration of various aspects of microsimulation models.

Analytical models are based on a scientific approach and are capable of modelling intersections, interchanges, freeways, rural roads, urban streets and networks with complex traffic conditions.  They provide unique value to transport planning and traffic engineering decision-making through balanced solutions that consider the conflicting needs of all transport users including pedestrians, cyclists, buses, tram / light rail, cars and freight vehicles.  This provides significant cost savings and environmental benefits.

Some technical issues in the use of microsimulation models are explained as a warning against decision making on the basis of limited viewing of animations generated by microsimulation runs without auditing their analytical soundness.
