Traffic management

Request a consultation

We develop traffic management plans for urban streets and development sites

What UTD designs

Traffic layouts and control devices

We design traffic layouts and plan the placement of signs, markings, signals and guidance devices. We align these measures with the site layout and traffic flows.

Connections within the site and to the city

We design access roads, entrances and exits, pedestrian routes, parking and access for service vehicles. We plan these connections in relation to the surrounding streets.

Improving road safety

We identify conflict points and hazardous sections, assess visibility and speed conditions, and propose measures to reduce the risk of crashes.

What UTD helps with

Traffic management plans for architectural planning briefs (APZ)

Traffic management plans for small sites

Traffic management plans for housing, shopping centres, offices and other large developments

Based on transport modelling results.

Measures for congested roads and junctions

Based on transport modelling results.

Measures for crash-prone roads and junctions

Based on modelling manoeuvres and turning radii.

How we substantiate each decision

	Infrastructure	Traffic flow modelling	Safe vehicle manoeuvres
What we study	Existing traffic management, signs and markings, street and junction geometry, and vehicle and pedestrian flows.	Capacity, queues, delays, interactions between vehicle and pedestrian flows, and traffic signal operation.	Whether design vehicles such as trucks, buses and fire engines can pass. We assess turning radii and swept paths, including conflicts with kerbs, poles and pedestrian areas.
How we check	Drone surveys, site inspections and instrument-based measurements.	Micro- and mesosimulation in Aimsun and PTV software. Open video	Vehicle path and turning radius analysis in AutoTURN. Open video
