Providing adequate visibility for a new access or junction can take large areas of valuable development land. The Stilwell Partnership's simplified Sightline-Calculator©, conveniently helps you investigate your visibility splays and maximise developable land without compromising road safety.

Manual for Streets (MfS), Design Manual for Roads and Bridges (DMRB) and even the Highway Code, all have differing results. (A 1mph change in main road speed, can result in a near doubling of stopping sight distance, simply by using the different Standard)

The Sightline-Calculator© provides a useful indication of the likely land-take and should not be used as a design instrument. To support your Planning Application or Planning Appeal, The Stilwell Partnership will undertake a Transportation Assessment including a detailed access design and risk assessment.
