Road Safety Engineering

We have built an enviable track record of expertise at all stage of road safety engineering in Urban and Rural locations. We have pioneered road safety techniques including the "Tracked Roundabout" technique, first introduced by the Stilwell Partnership in 1996 and now adopted on most major junctions throughout the UK.

Early projects included:

  • Safe Routes To School Pilot Project for Surrey County Council
  • Walton Area Road Safety Study for Elmbridge Borough Council
  • Lightwater Village Area Road Safety Study for Surrey Heath Borough Council
  • Road Safety Audits for Reading Borough Council.
  • West Drayton Area Studies for the London Borough Of Hillingdon.
  • Road Safety Audit Heathrow Terminal 5 Proposed Access
  • W S Atkins. Road Safety Audit M4 Widening at West Drayton


Preliminary Assessment meadows gyratory tracked roundabout

Initially we would undertake preliminary site observations, to identify and quantify the issues. We would specify and organise data capture for Traffic, Speed, and Accident assessments. Based on the analysis of the data and site observations, we would develop a number of feasible solutions to achieve the desired improvement in road safety.

If appropriate, we would consult with elected officials, statutory authorities, local organisations and the general public before arriving at the preferred solution.

meadows gyratory tracked roundabout plan Least Cost Solutions

We would consider low cost traffic management measures to improve road safety. These measures may include improved signing & white lining, Traffic regulation Orders, or minor works such as non-skid surfacing, build-outs, speed cushions etc. If necessary, we would develop a wider area traffic calming scheme applying the guidance of Manual for Streets 2.

Highway Improvements

Should the road safety issues require a more engineered approach, we would design Highway and Junction improvements with enhanced capacity, radii, and sightlines.

Road Safety Audits

As a final check that other potential road safety hazards do not arise from highway improvements, we are able to independently carry out Road Safety Audits, Stages 1 through to 4, based upon Highways England procedure DMRB Vol 5, HD 19/15 and the IHT Guidelines.

Project Description:

TSP was appointed to investigate the pedestrian and traffic movements in the High Street, assess areas of conflict and road safety concerns and prepare a design scheme to address these issues. The scheme was to be incorporated into a Public Consultation requiring the complex background issues and design proposals to be clearly presented.

Meadows Gyratory "Tracked Roundabout"

Comprehensive traffic & road safety study pioneering the tracked roundabout system.More >

Our analysis of the poor accident record revealed poor lane discipline and driver behaviour as a root cause. The Stilwell Partnership pioneered the use of Track markings. We worked with Wilson and Scott (white lining company) to develop a track marking, to work with the Spiral Marking concept. We also were the first to use plasta-flex.
