Crashes intersections

Figure 101. Dispersal of the one-swath application on May 15, 1962, as measured by the mean of two frosted glass disks placed on the ground at all grid intersections less than one hour before spraying and collected six hours later every 30.5 m along the path between intersections, and eveiy 15.2 m along lines running at right angles to the boundaries. The position of the crashed plane between thirteen and seventeen is shown. From Giles (1970).

Some order of magnitude of safe crash speeds has been adopted to guide our thoughts (Tingvall and Haworth, 1999). These should not be faster than 30 km/h for crashes between passenger cars and pedestrians/cyclists, while a safe maximum speed for lateral (side impact) collisions between passenger cars at intersections is 50 and 70 km/h for frontal (head on) crashes. 

Other vehicles can also constitute hazards that are unique to motorcycle riders. This is because car drivers detect other cars more easily than they detect motorcycles. A good rule of thumb for safe riding is that in interacting with cars and trucks it is much better for the motorcyclist to be safe than right. In Hurt et a/. s (1981) analysis of motorcycle crashes in California, they noted that one third of the crashes involved an obstruction of the motorcyclist s and/or car driver s view of each other in critical moments immediately preceding the collision. Furthermore, the hazards posed by other vehicles are often compounded by the specific roadway environment. Thus, crash statistics show that roundabouts and intersections can increase the likelihood of...
