The Vastern Road roundabout by Reading Bridge is by far the most dangerous area for cyclists in Reading.
The official collision records (STATS19) show 19 cyclist casualties in three years. These atrocious figures should be generating urgent action by Reading Borough Council. Unfortunately, four months after the issue being raised RCC have seen no remedial proposals, nor repainting of the worn road markings.
Most of the collisions appear to be failure to give way by motorists entering the roundabout and hitting a cyclist. Eight of these being northbound cyclists hit by vehicles exiting Vastern Road, three with cyclists exiting Vastern Road, and three with southbound cyclists hit by vehicles exiting Napier Road.
Five arm junctions like this tend to have a poor safety record, whether they are roundabout or signal controlled. The number and complexity of vehicle movements is probably a factor, with users less able to judge the intended route of others even if they are signalling.
There are a number of problems that make conditions difficult and dangerous for cyclists at this junction. They were noted by RCC at the time of construction, more than three years ago, and have been reiterated in recent months.
We see the problems as:
- The large carriageway widths and no circular lane markings encourage higher speeds than appropriate and poor lane discipline. The layout also encourages unsafe overtaking on the roundabout. The deflections of traffic feeding onto the roundabout are mainly inadequate to slow traffic and not to Department for Transport design standards.
- The current three lane approach from Vastern Road is made worse by the offside bus lane on the approach and the nearside lane changing from straight ahead to turn left, forcing most traffic into one lane from two, causing potentially dangerous lane swapping on the approach. This is a possible distraction from watching for vehicles and particularly cyclists on the roundabout.
- The two southbound lanes over Reading Bridge have generally caused problems with encouraging injudicious overtaking and use of the wrong lane, both of which can lead to knock-on problems at the roundabout.
- The two or three (unmarked) lanes that reduce to one narrow lane on the bridge approach are dangerous and do not conform to roundabout design standards.
- Cyclists have difficulty moving from the bus lane under the railway into the traffic lane for Vastern Road or Reading Bridge. Give-way markings on the Vastern Road approach in particular are now worn, making them less effective. The greater carriageway widths have also made conditions worse for pedestrians, particularly on the Reading Bridge arm.
Solutions or at least improvements to the junction should include:
- Provide some form of spiral lane markings on the circulatory sections. This may necessitate separating the northbound vehicle lanes for Vastern Road and Reading Bridge with lane markings under the railway bridge and in Forbury Road.
- Remove unnecessary carriageway space with hatch markings and/or preferably kerb build-outs.
- Reduce Napier Road exit from two lanes to one.
- Review the alignment of the car park entry and exits.
- Ensure that give-way and other markings are re-marked to maintain visibility.
- Consider partial signalisation of the roundabout with pre-signals for cyclists.
The current authorised give-way markings for a roundabout are a single dashed line as opposed to a much wider dashed line on mini-roundabouts and a double dashed line at give-way junctions.
A bolder give-way line is required at conventional roundabouts particularly large ones as at Vastern Road. What is really needed are the ‘shark’s tooth’ markings (see right) which are far more conspicuous and are almost universally used in other European countries. This would then replace the current three different types of give-way marking.
Will Reading try and agree a trial scheme with the Department for Transport?
