Traffic modelling

We provide traffic modelling to assess the operational performance of the highway network where development proposals may give rise to material transport impacts.

Our approach uses appropriate modelling techniques to respond to the scale and nature of the potential impacts. This may include junction modelling, network-based assessments or, where required, strategic modelling. We regularly use recognised industry software such as LinSig and TRL Junctions to assess junction capacity and operation, and we also have experience working with microsimulation models where these are appropriate to the complexity of a scheme.

All modelling work is undertaken in line with recognised industry methodologies and relevant guidance, and is carefully scoped to address the matters of interest to highway authorities. Assumptions and inputs are clearly set out to support transparency and effective review.

We focus on providing clear, defensible outputs that address the questions raised by decision-makers, inform the need for mitigation where necessary and support effective, constructive engagement with highway authorities throughout the planning process.

FEATURED PROJECT

Glass Processing Factory, Baglan

Apex was appointed to provide transport planning and highways support for the development of a new glass processing factory at Baglan Way.

The proposals comprised a large-scale industrial building with associated access arrangements, car and cycle parking, electric vehicle charging infrastructure and servicing facilities.

Our work included extensive traffic modelling to demonstrate the scheme did not have a material impact on the surrounding highway network.

Projects

Apex provided transport planning and highways advice to support an outline planning application for the Cardiff Peninsula development, a major mixed-use waterfront regeneration scheme.

The proposals comprise approximately 1,000 residential apartments, 300 co-living units, 11 townhouses, a 220-bed hotel, around 30,000 sqm of employment space, alongside retail, food and drink, community and leisure uses. The proposed masterplan will create a new and vibrant waterfront development for the community to live, work, relax and visit.

Apex prepared a Transport Assessment and Framework Travel Plan to support the application, with a particular focus on sustainable connectivity, active travel and reducing reliance on the private car.

Cardiff Peninsula

Apex provided expert highways and transport consultancy support for a proposed residential development of 125 homes at Farleigh Fields West, Backwell. The project progressed to a Public Inquiry, where Apex acted as expert witness for highways and transport matters.
