Traffic Engineering and Road Safety

More than just making vehicles and pedestrians move efficiently, traffic engineering ensures that infrastructure is safe, accessible, and designed for all road users. The imperative is to address traffic issues – from new developments to reconstructing existing infrastructure – to optimise mobility needs.

The objective of multi-modal transportation networks is to ensure the safe and efficient movement of people and goods on roads and highways. Traffic engineering helps resolve the issues that obstruct that process. 


Beyond the design and construction of transportation infrastructures, traffic engineering focuses on the functional aspects of road geometry that make it all flow, including traffic signs, traffic signals, intersection management and road surface markings.


Our traffic engineering services can help to:

  • Optimise road space
  • Develop road safety strategies and programs
  • Assess and implement traffic collision reduction measures
  • Accessibility, parking and traffic impact studies
  •  Integration of active transportation and transit into road designs
  • Intersection design and operation
  • Road safety studies
