ASSESSMENT OF VEHICLE HANDLING WHEN CROSSING TWO TYPES OF BUS LANE DELINEATOR
The effects on vehicle handling of two types of bus lane delineator have been assessed. One type of delineator consists of a rubber strip roughly triangular in cross-section. The other type consists of a hollow collapsible post 900 mm in height. It is shown that the rubber strip delineator poses severe handling problems for two wheel vehicles under wet conditions at small crossing angles. Larger vehicles had very little difficulty in crossing these delineators. The plastic posts have little or no effect on vehicle stability if hit a glancing blow. A direct hit by a two-wheeled vehicle can dislodge the post and lead to loss of vehicle control.
