I agree with the basic view of John Marriott's letter (NCE 21 January) but for different reasons.
What is suitable for entry slip roads to motorways is not suitable for all-purpose roads. Last February, international racing cyclist and civil engineer Peter Longbottom was killed on the A64 near Grimston Bar, York, where there is a two-lane entry slip road onto the trunk road. He was travelling on the main carriageway and was hit from behind by a motor vehicle coming from the slip road. The coroner considered the layout to be unsuitable for pedal cyclists.
Engineers should rethink from basic considerations the layout of all- purpose roads, particularly at such locations. Pedestrians, horse riders and pedal cyclists have a right to travel in safety on all highways. Major accident causes are speed differentials, injudicious overtaking, and leaving slip roads without anticipating the approach of other vehicles. The long-term solutions are either to provide an alternative safe route for non-motorists or not use such a layout.
In the short-term coning off entry slip roads to single lanes and enforcing lower speed limits on the main and slip roads are required. There are a considerable number of pedal cycle fatalities at such locations and a national not just a local solution is needed.
