Question

TfL have stated that the current cost of the A232 Shirley Road bus priority scheme stands at approximately £307,000. How can this cost for the eastbound section of the scheme be justified when TfL have also stated that primary journey time savings on the westbound bus lane during the morning peak period will be around 1.9 minutes per bus service yet the primary journey time savings on the eastbound bus lane during the evening peak period will be a mere 15 seconds per bus service, a figure which in any case looks a doubtful estimate bearing in mind the free flowing nature of that three lane route and ease of access onto the exiting roundabout ?

Whilst the total budget for the project is approximately £307,000 the eastbound elements of this are only expected to cost around £97,000. A large part of the cost of this project relates to bringing forward planned resurfacing of the carriageway. If this work is not brought forward then, having introduced the bus lanes, traffic would have to be disrupted in the near future as a result of necessary carriageway renewal works in this same section of road.

The journey time savings are based on predictions from detailed modelling that was based on recorded site information/data. TfL is confident that the benefits that this scheme is predicted to deliver, including improved bus reliability, will be realised.

Overall, the eastbound elements provide a first year rate of return of about 35% if the cost of resurfacing is excluded.
