4.68. Despite the stage by stage transfer of operations to Diamond Hill, Hok Yuen Quarry continued to meet very heavy demands for bituminous premixed road surfacing materials. This was generally achieved by the use of stone supplied from site formation contracts together with a limited amount from Diamond Hill.
4.69. The establishment of the new quarry at Diamond Hill continued, with most of the basic plant installed and quarry buildings completed.
4.70. Mobile quarry plant and the services of the quarry staff were extensively used during the aftermath of the June Rainstorm.
4.71. The several private quarries let on long-term contracts and administered by the Quarry Section were, with few exceptions, badly affected by the continued low demand for quarry products. Many private quarries let on short-term permits which were reviewed by the Quarry Section were similarly affected. A detailed report on the future supply and demand of quarry products and the future of permit quarries was under consideration.

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.
