7.5  Alignment

The approaches to level crossings should not include any substantial geometric features (curves, crests or intersections). Any reconstructive or corrective work near a level crossing should be designed to make it as straightforward as possible for approaching motorists. Where the angle between the road and rail is less than 85° or more than 110°, it can be extremely difficult for a driver, particularly of a truck, to get a clear view in both directions along the railway line.

In some situations, particularly at level crossings with passive controls, it may be more appropriate to sacrifice the design speed of an approach curve to accommodate a longer straight, or transition spiral, between it and the level crossing.

For uphill steep road approaches either side of a railway line, the risks of long vehicles grounding on the railway lines should be assessed and, if necessary, long road vehicle restrictions applied.
