4.72. Traffic flow on the roads of the Colony continued to grow. The number of new vehicles registered was substantially the same as last year and represented a compound rate of increase of 5.3%.
4.73. In addition to vehicle registration, the graph on page 47 shows the general trend of statistics for population, road mileage and accidents over the past decade. Both population and road mileage continued to increase at much the same rate as in the past few years but the curve for personal injury accidents shows a flattening over the past 4 years. In view of the general increase in vehicle registration and traffic flow, this flattening reflects the improved level of safety achieved through education, police control, road improvements and provision of the various traffic and safety aids.
