On a driving hazard problem

Abstract

A driving hazard problem was proposed by Baylis [1] and revised by Bender [2]. The problem can be described as follows: when making a right turn on British roadways, one moves to the right as far as possible on one's own side of the roadway and then turns. Unfortunately, the rear of the vehicle swings leftward as the right turn is begun - toward the unsuspecting driver passing on the left (Figure 1). This can be quite noticeable if the turning vehicle is a long bus. Hence the driving hazard problem - just how far will the back corner of the bus (P in Figure 1) swing toward the left as the bus driver negotiates the right turn - was proposed.
