8.5 Maintenance
|
8.5.1 The first traffic calming schemes were installed on public roads in the UK in the 1980s and maintenance of these older schemes is now becoming a problem for many local authorities across the country. Poorly-maintained traffic calming schemes can be a hazard to road users and pedestrians alike; as always the consequence of this hazard will often be most severe for motorcyclists.
Maintenance issues in general are dealt with in Chapter 6, but particular issues relating to traffic calming schemes include:
| • |
Reinstatement using non-original materials that present an inconsistent road surface to riders. |
| • |
Uneven wear on vertical measures, especially where block paving is used, leading to unexpected depressions. |
| • |
Road markings that fall below acceptable standards for retro-reflectivity and skid resistance (assuming they met them when new) or even fade away completely. |
