Highway & Junction Design

Our highway preliminary designs provide our clients with design options to meet their objectives under national and local design standards.

Well received by our clients, we can provide short to long-term junction design concepts with minimising land area in mind, efficiency and longevity supported by ARCADY, PICADY, LINSIG or TRANSYT.

The information supporting our designs provide our clients and highway authorities with confidence, with forecast queue lengths, DoS, performance index, saturation flows etc submitted.


    We were engaged by Transport for London to assess congestion concerns at the signalised junction during peak periods. Using LINSIG junction modelling software, we presented to the local highway authority a well-received incremental snap-shot why the junction was underperforming and provided a do-minimum upgrade design to improve traffic capacity. Our design was approved by the Local Highway Authority with an extension of the existing northbound right-turn lane constructed resulting in a significant reduction in delays and Practical Reserve Capacity (PRC). Following a further request, our junction design also included controlled pedestrian facilities linking the existing southern footway.

    'Excellent and very professional service provided by Ayen Consulting to support our Local Plan objection. Efficient data collection with robust analysis and clear presentation in a comprehensive technical report; all completed within a very tight timescale.'

  • Andy Stopps - Wingerworth Junior Sports Association, North East Derbyshire, UK

    'Our Grassroots football club have made an application to build a clubhouse to improve facilities. The project has some complicated objections around car parking and traffic management. As a club we had no experience or knowledge with regards to this and needed a consultant to work with. I approached Kevin and from the outset it felt like he understood our needs, talked us through the process, created a high quality piece of work and met all deadlines asked of him. We are grateful for all of the work and support given to us and wouldn't hesitate to recommend Ayen Consulting for this kind of work.'
