Traffic Modelling

All our modelling services are available at short notice and at very competitive prices. We can deliver fast and robust models without compromising quality.

Basic traffic models

Basic traffic models are available from the rates shown below.

Model	LinSig	Picady	Transyt	Arcady
Simple Junction	from £245	from £195
Simple three node network	from £695		from £995
Four arm roundabout	from £695		from £1195	from £345

We assume that a "basic model" will consist of a maximum of two flow groups (e.g. AM and PM peak) and that all relevant information such as scale drawings, traffic flows and intergreens will be supplied by the client in an agreed format.

Additional services

As well as basic models, we provide a range of model related services on a fully flexible basis.

• Multiple Flow Groups - Much of our traffic modelling is done as part of transport assessments, and can require many different flow groups, taking into account base and future assessment years.
• Existing Junctions/Networks - Sometime models are required in circumstances where existing details are incomplete. We can often help fill in the gaps, making site visits as necessary, and checking the validity of the results.
• Proposed Junctions/Networks - Proposals for junctions and networks may exist only in geometric outline, but we can develop the details required for modelling including signal phasing and intergreen measurement.
• Technical Reports - As well as model hand-over, we produce technical reports explaining modelling assumptions, tabulating results, drawing conclusions, and highlighting any opportunities for enhancement.
• Concept Geometric Design - For proposed junctions and networks, we add detail to geometric proposals or produce complete geometric layouts. This can enable the basis of the modelling to be more easily envisaged
• Ongoing Advice - After completing the initial work, we are always happy to provide ongoing support and justification. We can attend meetings, deal with any criticisms, give presentations, or prepare more formal representations.
