Traffic calming and 20mph zones

A traffic calming priority-ranking system for residential areas in Doncaster was established in 1993, in order to take account of legislation which allowed the designation of 20 mph speed limits by local highway authorities.

The borough is divided into 102 residential areas and priority is assigned according to the number of road traffic collisions within each area in relation to the length of road. 

Each incident is weighted to give greater importance to incidents involving children, vulnerable road users and to those incidents where speed was considered to be a causation factor.

The traffic calming strategy has provided valuable casualty reductions by targeting the highest priority areas which had the most serious casualty problems. However, the continuation of the programme to areas of lower priority would result in much lower casualty reduction benefits, for equivalent or greater expenditure and resource requirements, as there are fewer casualties in these areas.  Many of the lower priority residential areas actually experienced no road traffic casualties at all during the three-year study period.

Of all the casualties which occurred in the 102 residential areas during the study period, 82% were contained within the 40 areas designated as ‘Top’ and ‘High’ priority. Traffic calming and other road safety improvements have now been delivered, or are planned in the majority of these areas.

There are, however, wide variations in casualty numbers between areas and it should be noted that during the study period, the total number of casualties within the 102 residential zones represented only around 15 per cent of the overall total number of road casualties within the Borough. This clearly highlights the need to target the main road network as the source of the most serious road safety problems.

It has therefore been necessary to reconsider the traffic calming strategy, in order to permit the re-focusing of resources and expenditure to areas of greatest potential benefit, largely to locations of concern along the main road network. Any emerging residential area road safety problems will continue to be monitored and addressed as necessary on a priority basis as part of the continuing overall casualty reduction strategy. Doncaster does, however, now have one of the highest levels of 20mph areas within the region.

The traffic calming schemes delivered in recent years have more closely targeted remedial measures to the actual casualty problems in each zone, rather than simply applying traffic calming and a ‘blanket’ 20 mph limit throughout the area. This approach will be continued in the delivery of future residential area road safety improvement schemes.
