This was discussed in Chapter 5.6.2.6 The total value of current commitments to highway construction is estimated at$23 billion, of which some $10-11 billion remained to be spent from the beginningof 1989.6.3 Candidate Highway Projects6.3.1 Candidate highway projects evaluated by CTS-2 came from three major sources:(1) Projects in the Public Works Programme, most of which were developed byHighways or Territory Development Departments, including further stages ofcommitted improvements.(2) Suggestions and recommendations from previous and current transport andplanning studies such as the Harbour Reclamation and Urban Growth (SHRUG)Study, Territorial Development Strategy (TDS) Study, etc.(3)^ Projects to address traffic needs or problems identified in the CTS-2 testingprogramme.6.3.2 The candidate highway projects considered by CTS-2 are shown in Table 6.2 andillustrated in Figure 6.2. Many of these were conceptual projects without detailedtraffic or engineering feasibility studies. The approach taken in each case was for theCTS-2 to develop a preliminary design and agree on details with HighwaysDepartment after review.6.4 Highway Project Evaluation6.4.1 As discussed in Chapter 4, the limits to investment in transport infrastructure are setby the transport budget likely to be available. Hence highway projects identified forpossible implementation required to be evaluated and assigned relative priorities forinvestment. Three aspects were considered, as discussed below.Traffic Operations6.4.2 Projects were first examined from the point of view of traffic operations, assessingthe volumes of traffic carried by the project and the traffic congestion relief given toother parts of the transport system. The traffic performance was measured by thepeak period volume to capacity (V/C) ratio, as discussed in Section 5,7 of Chapter 5.97
