Based on the basic criteria, including capacity, efficiency and technical feasibility, Cable Car, Extension of Existing Light Rail, Monorail and Personal Rapid Transit are considered not suitable modes as EFTS for HSK/HT NDA and YLS Development.
The performance of Automated People Mover, Green Bus System and Modern Tram in terms of capacity, efficiency and technical feasibility in general could meet the requirements of EFTS for HSK/HT NDA and YLS Development. These modes are therefore shortlisted for further comparison.
APM is a fully automated system and operates on fully dedicated elevated rail-track which is fully segregated from pedestrian and other vehicles without being affected by road traffic.
Cable Car is pulled by overhead cables, which operates at a slow speed and has low carrying capacity. It is usually used for tourism transportation instead of serving as a daily public transport system.
The existing Light Rail is manually operated by a driver on sections of dedicated and shared corridors. Some of its sections share the road spaces with other road traffic at junctions and the service performance is therefore limited.
GBS operates along a dedicated bus lane. To enhance the boarding and alighting efficiency, station can be provided with ticket gates and screen doors. The GBS in HSK/HT NDA and YLS Development would be served by green energy bus (e.g. electric bus). When necessary, GBS can also operate on general public roads to serve a wider area.
Modern Tram is manually operated by a driver and can run on dedicated rail-track. It generally allows pedestrians to cross the dedicated rail-track at at-grade crossing. Its lowfloor tram car and station design offer convenient boarding and alighting.
Monorail is a fully automated system and operates on dedicated elevated rail-track without being affected by pedestrian and road traffic. While monorail can provide sufficient capacity and efficient service, the monorail system requires a relatively large turning radius which does not fit in the planned alignment of EFTS in HSK/HT NDA and YLS Development.
PRT is a system of small automated electric vehicles offering on demand travel from point to point for individuals and small groups, which can only meet relatively low transportation demand.
