Halfway Street/Willersley Avenue, Bexley

This hybrid roundabout was suggested by me as part of a Safer Routes to School scheme in Sidcup, Bexley implemented in the summer 2001. It would have removed virtually all the through traffic past the schools at their busy times allowing a relatively easy bypass. Congestion in Willersley Ave (opposite) which was a side-road prevented easy access to Halfway Street. The scheme was introduced only after all the alternative options were rejected. Hollies Avenue (towards the bottom) might have been closed to enable a 3-arm mini-roundabout to be installed but local residents objected strongly. Signals were tested and failed on capacity grounds. Initially the four-arm roundabout failed an Arcady test; however using my own formula I suggested that there would be no congestion on the basis of the figures analysed. Once approved by the council, it was necessary for a special authorisation as the central island was to be larger than the standard 4m. The scheme was implemented in June 2005 and has worked well with only very minor accidents attributable to the junction operation.

Yarnton Way, Bexley
 Transport Road Safety Award 2005 nominee

This was the highway part of a major Safer Routes to School scheme constructed in 2004. Installing the four roundabouts along Yarnton Way was just one of the innovative safety features that I recommended.
I proposed too that the carriageway should be reduced to a single lane in each direction and have cycle lanes added. This reduced overtaking and provided more space for traffic to wait in the now widened central reservation crossovers. An additional Toucan (cycle and pedestrian) crossing was installed; secure cycle racks were introduced at Bexley Business Academy. New cycle routes to link up with residential areas to the north remain to be constructed. The scheme is located in a relatively poor area of North Bexley and received much support from an initially nervous local populace.

TRAFFIC TROUBLESHOOTING
 ... solving traffic and safety engineering problems
Mini-roundabouts & normal (or modern) roundabouts I will advise on the use and design of roundabouts of all sizes anywhere in the world. For more information, go to MINI-ROUNDABOUTS
Area Traffic &
Safety studies		 Traffic Calming cannot be carried out on an individual road without affecting the next ones. Area traffic and Safety studies include a comprehensive approach to the problems improving the environment by making the road network function effectively, efficiently and safely, particularly in residential areas. A strong emphasis on liveability.
Transport Assessments PPG13 advises the need to ensure that single occupancy car journeys particularly for the journey to work are minimised. I will advise on the highway implications of developments, suggest alternatives where practicable and negotiate with the highway authority on your behalf.
Park & Ride Instrumental in the implementation of the Canterbury Park & Ride project and assessment and development of the Medway Towns proposals. Based on parking demand and supply, Park & Ride has to be part of any traffic and transport plan for your urban area.
Safer Routes to School Comprehensive approach to management of school traffic including assessment of different modes of travel, potential alternative routes for pedestrians and cyclists, traffic calming at school entrances.

For more information go to TRAFFIC CALMING then link to school entrances.
Village and Town Traffic Management Comprehensive assessment of the whole small town or village traffic scheme to make the environment more liveable, reducing excessive speed, providing a complete pedestrian & cycle network, safer routes to school, the works.
Traffic Calming Extensive experience of traffic calming schemes, mainly in urban areas.

For more information see TRAFFIC CALMING
