Since this was installed I have been asking questions about the ‘table element’ at the actual junction. I like others who have contacted me have been concerned about how ‘sharp’ the ramp element is to the ‘table part’.
I have now, at long last, got some information that will result in the ramp parts being altered. The reply I have just received is below:
I have now in possession of the definitive survey data for the problematic ramp at the Fraser Street / Rochdale Road junction. The results and conclusions of the exercise are listed below:
- From a legal perspective, the as-built dimensions are still within the limits specified in the Road Hump Regulations.
- The 1 in 11 gradient of the problematic ramp is more in keeping with the geometry you would expect on a residential access road not a main distributor
- The problematic ramp with be extended to create a gradient of 1 in 15. This new gradient will then conform to the GMPTE’s “bus friendly” requirements.
- Arrangements are being made carry out the remedial works as soon as possible in the coming weeks.
Apologies for the conflicting information that has been provided up to this point; action is being taken by the Highway Construction / Site Supervision team to avoid this type of problem being repeated.
