David A Graham Associates brings over 20 years of experience in Road Safety Audits, working with local highway authorities, residential developers, engineering consultants and commercial organisations.
Our experience covers a wide range of highway schemes across the UK, including local roads, strategic trunk routes and motorway networks. We work collaboratively with clients to deliver independent, practical Road Safety Audits tailored to the needs of each scheme.
Our audits cover a broad range of highway infrastructure, from priority junctions and vehicle access points to major arterial routes, signalised intersections and large residential developments.
Our comprehensive project portfolio includes:
New Road Infrastructure: Motorways, dual and single carriageways, link roads, and primary spine or distributor roads for new developments.
Commercial & Residential Projects: Diverse land developments, including schemes delivered under Section 278, Section 38, and Section 111 agreements.
Grade-Separated Junctions: Multi-level interchanges featuring flyovers, underpasses, connecting links, slip roads, loop configurations, and compact grade-separated designs.
At-Grade Junctions: Standard and signalized roundabouts, mini-roundabouts, traffic light intersections, major/minor priority junctions (including right-turn ghost islands), as well as commercial and private access points.
Rapid Transit Systems: Light rail and tram lines, dedicated tram stops and signaling, Bus Rapid Transit (BRT) routes, bus priority corridors.
EV Charging Points: We have carried out numerous Audits of on street EV charging points.
Pedestrian & Cycle Infrastructure: On- and off-road cycle tracks, footpaths, sidewalks, and a full range of pedestrian crossings (including Toucan, Pelican, Puffin, Pegasus, and uncontrolled variants).
Traffic Management & Calming: One-way systems, mini roundabouts, two-way streets, updated signage and lane markings, and diverse traffic calming interventions (such as road humps, speed cushions, chicanes, and gateway features).
Public Realm & Urban Regeneration: Shared spaces, integrated surfaces, upgraded street furniture, and high-quality repaving initiatives.
