DIDCOT TRANSPORT ISSUES STUDY

DIDCOT TRANSPORT ISSUES STUDY: OUTLINE STUDY RECOMMENDATIONS

Consultant Recommendations

DES Comments

Cycling

In order to encourage more cycling for all types of journey up to a medium distance and to reduce reliance on cars, the consultants recommend an extensive network of joined up routes. The network includes key routes leading from Didcot, other mainly rural routes and a finer network of routes within Didcot. This will mean improving existing routes and creating new routes both on and off road.

Recommended improvements include crossings at main roads, safer junctions, traffic calming and cycle parking. Total cost of these measures could be in the region of £5m. Cycling promotional measures are also recommended.

 

 

Implementation of these recommendations would provide good safe routes to key destinations from Didcot and generally within Didcot. For those able to cycle this would become an attractive alternative to travelling by car. All the proposals would need careful detailed design and local consultation to satisfy local concerns. There would therefore be extensive preparation work which would need to be spread over several years. The aim should be to complete the proposed network within a programme that gives priority to the improvements that will give the greater benefits.

Bus Services

The consultants recommend improving the reliability, frequency, and convenience of the bus services. The largest change would be to increase the frequency of the service via Milton Park to Abingdon and Oxford to 15 minutes and to divert it to serve the new housing area to be developed west of Didcot. The service would be diverted onto A34 between Milton and Abingdon and bus priority measures may be needed within Abingdon and along A34.

New regular hourly services are recommended between Didcot and the Astons and between Didcot and Berinsfield. Within Didcot the former D3 town service would be replaced by separate hourly services

  1. to serve the station and areas to the south of Broadway (as recently introduced), and
  2. to serve the station and areas north of Broadway.

An additional peak period service to serve the station, south Didcot and Milton Park is proposed.

The consultants also recommend new shelters at bus stops, improved timetable integration and inter-service ticketing.

 

 

 

In making these recommendations the consultant has considered the expected passenger market demand, the operational fleet requirements and operational costs. The programme for introducing these improvements will range from the town service that has recently been introduced to the improved frequency rerouted service to Milton Park, Abingdon and Oxford, which is dependent on progress of the major housing area to be developed west of Didcot. Bus priority measures will need to be considered in the A34 multi modal study.

Together, these improvements would substantially increase the convenience and opportunities for people to travel to and within Didcot by bus, without unreasonable subsidy requirements. It is expected that the housing development west of Didcot would contribute to the costs, particularly of introducing the improved frequency of services to Abingdon and Oxford.

Didcot Station

Changes to the station forecourt are recommended to reduce congestion and to improve interchange for passengers between rail, buses, taxis and cycles, to improve access for pedestrians and to make better provision for short stay car-born traffic. Growth in long stay car parking is proposed to be accommodated by decking the Foxhall car park and improving the pedestrian route to the station with a covered walkway and lifts. Longer term improvements from the Foxhall car park might include a travelator and direct links to platforms 2 and 3.

The consultants comment on Railtrack aspirations to improve the level of service by building new platforms on the avoiding lines enabling some through trains to Oxford to stop at Didcot. The improved service is welcome but this is considered to be expensive and it is noted that, compared with the existing Oxford platform, passengers from Didcot or changing trains would have much further to walk. A further proposal for a pedestrian route through the station to Ladygrove would benefit some passengers but could result in some "kiss and ride" traffic and car parking pressures near the new entrance.

 

 

The proposed arrangements would reduce congestion and improve safety at the station entrance. Adequate space is proposed for all bus routes to call at the station, reducing the need for people to travel to the station by car. In the longer term growth in rail services is likely to attract more passengers, many of whom will arrive by car. Provision of long term parking at Foxhall Car Park, with improved access to the station, would help to avoid increased traffic through the centre of the town.

Some of the changes may take several years to achieve and will require the cooperation of Railtrack.

The proposed changes would increase the value of the station for Didcot, but it has to be accepted that it may take some time to agree the detail to achieve the changes.

Pedestrians

The consultants have identified a number of key routes for walking in Didcot and recommend improvements to make them safer, more convenient and attractive. Traffic calming is proposed on these routes to improve the pedestrian environment. Footways along these routes should be kept in a good state of repair. At some crossings of side streets raised pedestrian crossing facilities are proposed; at others dropped kerbs and tactile paving should be introduced.

A proposal for Broadway is recommended that would reduce the traffic width to two 3m lanes and provide parallel parking, separate cycle lanes, raised pedestrian crossings and raised tables at junctions. The consultants also comment on details of the Civic Trust’s report on Didcot Town Centre.

 

 

 

These proposals would improve the attraction of Didcot as a place where pedestrians are welcome, by reducing the amount of traffic, reducing noise and increasing safety.

Car Parking at Didcot

The consultants consider that currently there is no real shortage of parking space in the town. Increased housing at Didcot and increasing employment in the town centre will tend to increase demands for employee parking throughout the day. The consultants recommend that the level of enforcement of parking controls be reviewed so that they become respected and effective. Some extension of the commuter parking controls near the station should be considered. Any lack of town centre employee car parking should be accommodated outside the central area, but within walking distance.

 

 

 

This is an area that will need to be closely monitored once the new town centre changes are in place and as Didcot development proceeds. A future review of parking policy is likely to be needed.

West Didcot Housing Development

The consultants’ proposals for Didcot include identified pedestrian, cycle and bus routes through and serving the housing development area. Traffic generation from this development is included in the consultants’ assessments of proposals throughout the Didcot area.

The consultants have assessed the proposal put forward by a developer to provide a bridge over A4130 and the railway to make a direct link between the development and Milton Park, and have compared this proposal with the alternative of increasing traffic capacity at the Power Station and Manor Bridge roundabouts. The benefits of the proposed bridge are the improved direct routes between Didcot and Milton Park for cyclists and buses. The disadvantages are the tendency to increase traffic through Milton village and Sutton Courtenay, also the high cost of the bridge that might be better spent on other transport improvements.

 

 

 

The weakness of the bridge proposal is that it does not support the main highway network. The consultants have shown that it is feasible to increase the capacity of the Power Station and Manor Bridge roundabouts so that there would be no significant delays that would trigger the need to add bus priority measures to protect the integrity of bus services. Improving the network in this way is a more robust provision for the various traffic movement needs. If the bridge were to be provided in addition, but just for use by buses and bicycles, there would be clear benefits for these users, but it is doubtful that the cost could be justified.

Highway Network

The consultants have used a traffic model to forecast the morning peak hour traffic in 2011 throughout the study area, taking account of future development. Their recommendations for traffic proposals result from the evaluation of alternative options on a range of criteria. These include targets to reduce traffic flows to levels forecast in 2011 without the development and to reduce delays at junctions on the major highway network to a level that generally maintains the attraction of the major routes over minor roads for through traffic. To make better use of the main road network, junction capacity improvements are recommended at Rowstock, Milton Interchange, Manor Bridge and Power Station roundabouts and at the Avon Way roundabout on the Didcot perimeter road.

The consultants have investigated schemes particularly to reduce traffic through villages near Didcot. To relieve villages south west of Didcot they recommend adding north facing slip roads to the A34 at Chilton and south facing slip roads at B4493, Wantage Road. However, A34 is managed by the Highways Agency and will be the subject of a major multi-modal study over the next two years. In the event of the new slip roads being ruled out the consultants recommend construction of a new link between B4493 and A417 alongside A34 to bypass Harwell.

The consultants have found that a new river crossing near Appleford would reduce traffic at Culham (Sutton) and Clifton Hampden bridges, but would increase traffic in Abingdon. Also they recognise that such a scheme could not be approved in advance of the County Transport Networks Review and would not be available within 10 years. They recommend that alternative measures to reduce traffic at these bridges should be considered, including restricting the use of the bridges in the peak hours for buses only and restriction by tolls.

 

 

 

 

 

 

 

 

 

 

 

 

 

These junctions all lie on the A4130 main road.

 

 

 

These alternative proposals are significant for local traffic movement but would not create a new major connection in the county network. Therefore promotion of either scheme need not await the outcome of the County Transport Networks Review. Early adoption in principle would bring forward the view of the Highways Agency. Since procedures for new lengths of highway are long in any case, an early start is indicated.

The consultants’ other recommendations for public transport improvements and improvements to the main highway network, particularly at the junctions, reduce the need for traffic, other than local traffic, to use these bridges. If severe problems of through traffic persist, restraint measures could be considered, though these may make local access less convenient.

Traffic Calming and Traffic Safety

The consultants recommend traffic calming schemes for certain villages should be drawn up in close consultation with each village. Besides reducing vehicle speed, traffic calming can sometimes reduce through traffic. The consultants recommend that traffic calming is appropriate only in conjunction with street lighting.

The consultants have drawn up outline proposals for road safety improvements at ten junctions with safety problems. They recommend that detailed schemes be prepared for implementation when funds become available.

 

 

Many villages were not happy with draft proposals and some do not want street lighting, though village "Gateway" treatments and proposals for speed cameras were generally well received.

 

 

Before programming, these proposals will need detailed design, evaluation and consultation.
