Road Safety Review: critical aspects of powered two wheelers

Powered two wheelers (PTW) differ in their use of the road in a number of ways from other vehicles and they have different needs. Predictable road geometry, good visibility, obstacle free zones and good quality road surface with high levels of skid resistance are some major examples. While important for all road users, they are essential for PTW. So the design of safe infrastructures for all travellers categories, included the motorcyclists, becomes a primary requirement. To obtain these results, Road Safety Audits and Road Safety Reviews are very useful tools. In this way, in fact, it is possible to examine a project or existing road, reporting its crash potential and safety performances and detecting its deficiencies without waiting for accidents accumulation. In this paper the author, starting from data collected in numerous Road Safety Reviews on urban streets, provide significant results regarding roads project and maintenance in according to safety needs of all users, included the PTW drivers.
