OVERCOMING THE CAPACITY CONSTRAINTS ON CENTRAL BUSINESS DISTRICT'S COMMUTERS

摘要

The study points out that: l)the capacity of urban road network - and rail transit system are important factors that influence the employment density and commuters scale in CBD; 2) restricted by limited land resources and increased travel cost, the capacity of urban road network and parking lots will be expected to approach a limit, resulting in a definite upper limit of non-transit work trip density in CBD; 3) there is a significantly positive correlation of employment density in CBD with transit work trip density and its market share, illustrating that only mass transit system can sustain higher employment density in CBD with the advantage of saving land resources and expanding capacity.
