2.5.9 A literature review was made <strong>of</strong> potential transport policies for the management <strong>of</strong>transport demand. A set <strong>of</strong> policies considered to have potential for application in<strong>Hong</strong> <strong>Kong</strong> were agreed for testing by CTS-2.2.8 Analysis Evaluation <strong>of</strong> Transport Projects,and Policies2.6.1 <strong>The</strong> testing <strong>of</strong> transport projects and policies followed a clearly defined programme,with evaluations <strong>of</strong> results at each stage. <strong>The</strong> sequence <strong>of</strong> testing and the approachto evaluation are discussed below.Testing Programme2.6.2 A sequence <strong>of</strong> seven rounds <strong>of</strong> testing were conducted in developing the transportstrategy as described below.2.6.3 Committed Network Tests—Transport projections were made assuming completion<strong>of</strong> only those projects currently under construction or otherwise firmly committed,and with no change in current transport policies. Projections were made for thethree years 1991, 1 996 and 2001. <strong>The</strong>se tests indicated the scale <strong>of</strong> likely problemsconfronting transport planners to the end <strong>of</strong> the century and provided the backgroundagainst which new projects and policies could be justified.2.6.4 Maximal Network Tests—Transport projections were made assuming construction<strong>of</strong> a large number <strong>of</strong> transport projects, but assuming that current transport policieswere maintained. Five different transport network-configurations were investigated,all with the same highway plans but with different combinations <strong>of</strong> rail projects.Tests were made for the year 1996 only. <strong>The</strong>se tests indicated the scope for resolvingfuture transport problems by the construction <strong>of</strong> new infrastructure only.2.6.5 Policy Tests—-Eight different policies for managing the growth <strong>of</strong> transport demandwere investigated, assuming no further construction <strong>of</strong> transport projects beyondthose already under construction or otherwise firmly committed. As with the MaximalNetwork tests, the policy tests were undertaken for the year 1 996 only. <strong>The</strong>se testsindicated the scope for resolving future transport problems by new policy initiativesonly.2.6.6 Initial Strategy—Based on the results <strong>of</strong> the first three rounds <strong>of</strong> testing, an InitialStrategy was devised combining new transport projects and policies. Projectsselected for the strategy were compatible with estimates <strong>of</strong> the transport investmentbudget up to 2001. <strong>The</strong> strategy was tested and evaluated for the two years 1996and 2001, but with ail new projects included for both years. While the assumptionthat all new projects could be completed by 1996 was unrealistic, the results <strong>of</strong> thetests provided useful information <strong>of</strong> project priorities.2.6.7 Revised Strategy—Following the evaluation <strong>of</strong> the Initial Strategy, a RevisedStrategy was prepared selecting a realistic programme <strong>of</strong> transport projects forcompletion by 1996 and 2001. Testing was carried out for both these two years.2.6.8 Sensitivity Tests—A series <strong>of</strong> sensitivity tests were undertaken on the RevisedStrategy to assess the implications <strong>of</strong>;— Higher economic growth— Variations in population distribution.— Variations in cross-border goods vehicle flows.2.6.9 Final Strategy—A final set <strong>of</strong> tests were made for 1996 and 2001 incorporatingminor adjustments to the Revised Strategy based on the results <strong>of</strong> the sensitivitytests.Evaluation2.6.10 <strong>The</strong> transport projects and policies examined in each round <strong>of</strong> testing wereevaluated from several different viewpoints as discussed below:27
