The most critical points in urban travel are, without question, junctions and the road networks that connect them. A poorly designed junction can disrupt the flow of an entire network and lead to serious collisions. Traffic circulation design and intersection studies are therefore an indispensable part of modern, safe city planning.
Traffic Circulation Design: The Heart of Urban Travel
Traffic circulation design is a strategic approach that establishes how vehicle, pedestrian and cycle movements in an area can best be managed. It covers far more than carriageway widths: one-way arrangements, parking layouts, public transport routes and pedestrian crossings all form part of it.
On our circulation design projects, we focus on the following:
- Collection and analysis of traffic data
- Identification of existing congestion and safety problems
- Development and simulation of alternative circulation scenarios
- One-way arrangements, revised lane layouts and signal plans
- Creation of safe corridors for pedestrians and cyclists
Intersection Studies and Optimisation
Junctions are the nodes of the network. A junction's geometry, signal plan and capacity directly affect the whole of the traffic system around it. A sound intersection study does more than analyse present conditions: it anticipates future demand and offers solutions that hold up over time.
The main intersection study services we provide:
- Traffic counts and demand assessment
- Analysis of existing junction performance (delay, queue length and similar measures)
- Feasibility of alternative junction types (roundabout, signalised, grade-separated)
- Optimisation of junction geometry and lane arrangement
- Development and simulation of traffic signal plans
- Analysis of collision data and safety improvements
Our specialist team works on traffic circulation and intersection studies to make your cities safer, freer flowing and better to live in. Using advanced modelling and simulation tools, we analyse every project down to the finest detail and see the most appropriate solution through to delivery.
