Transport Consultant
In short, a visibility splay drawing is a way to prove it is safe for vehicles to emerge from your proposed exit onto the highway.
Normal requirements for visibility splay drawings would be to show how far it is possible to see along the highway with an unobstructed view. For example a 30 mph speed limit would require 43 meters unobstructed view within Manual for Streets specification, and a 60 mph speed limit would require a 215 meter visibility splay in accordance with the Design Manual for Roads and Bridges (DMRB for short).
It is possible to reduce this requirement if you know the actual speeds vehicles travel along the road and we can arrange this for you. This will increase the lead time of your drawing to approximately 3 weeks and you will also be provided with a report justifying any decrease in visibility splay.
Adverse weather conditions change vehicle travel speeds, therefore it is sometimes possible that surveys will take longer than anticipated - we will keep you informed if this is the case.
