The Study Approach
1.9
1.10
The technical approaches adopted have made maximum use of
previous work and in particular of data and procedures developed during the Comprehensive Transport Study (CTS).
A substantial amount of new work has been undertaken in the
area of alternative transport system definition and in
costing and also in the field of evaluation methodology.
The conduct of the study has involved four principal steps;
(i) Adjustment of the CTS demand forecasts to reflect
land use changes, existing flows and trends in the corridor and the policy assumptions appropriate
to the ICS;
(ii)
The preliminary development and screening of a wide
range of alternative transport systems for the
corridor leading to the detailed specification of
a limited number of options for comprehen sive
evaluation;
(iii) The comprehensive evaluation of four options with
particular emphasis on the financial impacts,
the cost/benefit impacts and the operational
performance of the systems; and
(iv) The development of a recommended transport strategy
for the corridor together with an implementation
programme for the short and medium term.
Existing and Future Problems in the Corridor
1.11
Interim Reports 1 and 2 provided a clear statement of the
existing travel conditions and flows in the corridor. In particular Figure 1 shows the vehicular and person flow
at different points along the corridor in early 1977.
The CTS provided a detailed analysis and assessment of likely future conditions. The existing and future problems in
the corridor may be characterised as follows:
