CONTRAM
CONTRAM - CONtinuous TRaffic Assignment Model - is a Windows-based
program jointly developed by Mott MacDonald and TRL for modelling
traffic flows, queues and delays.
CONTRAM models drivers’ route choice through urban or inter-urban networks and the consequent queues and delays they experience. Delays are modelled using detailed representations of junctions: signals, priority junctions and roundabouts. This enables impacts of changes in the road network – or in demand – to be predicted, making CONTRAM an invaluable tool for transport planners.
CONTRAM is fully dynamic, which means it can model the build up and decay of queues throughout the day and the impact this has on route choice behaviour. Other features include an ITS option, which models the impact of information provision on incident management, and a dynamic trip matrix estimation facility.
Data can be entered and results analysed via the graphical interface, allowing models to be set up quickly, and results to be presented in a user-friendly way that’s easy for non-transport planning specialists to understand .
CONTRAM has users world-wide, from North America and the Caribbean, through Europe to Australia. It’s been used on a wide range of projects, from examining the impact of improving an isolated junction to modelling large regions with several major cities.
The latest version includes an evaluation copy that contains the full software functionality for up to 25 zone networks. This may be used free of charge for non-commercial applications and may be downloaded from the contram website. It also includes tutorials that guide new users through some basic CONTRAM operations.
CONTRAM - CONtinuous TRaffic Assignment Model – is a Windows-based program jointly developed by Mott MacDonald and TRL for modelling traffic flows, queues and delays.
What size of road network has CONTRAM been used on?
CONTRAM has been used on networks as small as a single junction to strategic traffic models of large regions.
How do I enter data in CONTRAM?
Network and junction data can be entered using the graphical interface. A number of templates are used to simplify the data-entry process, particularly for signalised junctions.
How do I analyse results?
The graphical interface can be used to analyse results. A number of different analyses are possible:
Can I use CONTAM to model the impacts of ITS (Intelligent Transport Systems)?
Yes, CONTRAM can be used to model how drivers change their route choice in response to information sources such as variable message signs (VMS).
How can I find more information about CONTRAM?
You can find more information on the CONTRAM website where you can also download a demo version.
