3.11 There are 631 miles of roads in the Colony. The total number of vehicles registered on 31.3.73 was 193,434, an increase of 14.1% during the previous 12 months.
3.12 On the average, traffic volume at cordons and screen lines in 1972 increased by 5.6% over the corresponding values for 1971. The highest traffic flow occurred in Prince Edward Road in Kowloon City where the average week-day figure for 1972 was 107,000 V.P.D., an increase of 27% over the figure for 1971.
3.13 The Department commissioned a firm of consulting engineers (Freeman, Fox, Wilbur Smith & Associates) in 1967 to make proposals for the future development of the major road network. Their report was published in 1968. The recommendations contained in this report, together with traffic data from 270 permanent monitoring sites throughout the Colony, are used by the Highways Office to formulate a programme of construction and improvement giving recommended priorities for works. The programme is revised annually for approval by the Roads Committee and the Transport Advisory Committee, the latter body having both official and unofficial membership.
3.14 Due to rapid change of factors influencing transport demand and travel characteristics, a thorough up-dating of the information given in previous major transportation studies was felt to be necessary and Wilbur Smith & Associates were commissioned on 1st March, 1973 to carry out this updating.
3.15 A 5-year forecast of expenditure, which is updated annually at the start of the financial year, was prepared on the basis of the Road Priority Programme mentioned earlier. The Works Programme of Road Construction and Improvement was sensibly prepared, taking the staff and resources situation into account. This is updated annually and approved by the Public Works Sub-Committee of the Finance Committee at the first of the three review meetings held each year.
Drainage and Water Pollution Control Projects
3.16 A review of the capacity of existing sewer systems has been undertaken to formulate recommendations for improvement works where necessary to cope with development. Sewer gaugings are also being carried out in different types of developments to check the validity of design criteria. A model has been constructed for the study of drainage characteristics of road pavement and the performance of gully gratings pertinent to Hong Kong conditions.
