1、The traffic of a metropolis is characterized with staged expansion,developing from traffic motorization through urban expansion till restructuring is a typical law to be followed by the growth of cities from home and abroad.The law of staged expansion of urban traffic underlies planning of urban tra

3、n traffic developing stage giving priority to administration,On the cohesive developing stage of non-motorization,trip distance in a city is very short,traffic demand is extremely low,much less resource of urban traffic system is occupied by any single trip,so with such a road system as formed on th

4、e basis of urban land,there is comparatively rich traffic supply capacity.The main features of urban traffic:Mingled traffic composition and mixed vehicle flow leading to traffic disturbance;Public transport depending upon conventional bus or trolley coach on ground;,Cohesive developing stage of urb

5、an traffic dominated by non-motorized transport,(I),On initial period of motorization,a city has been gradually changing from mixture to zoning with clear functional partitioning,thus leading to the increase of trip distance and gross traffic demand combined with motorization,conflict between traffi

6、c supply and demand is emerging and then attention shall be focused on increasing supply to satisfy urban expansion.The main features of urban traffic:Rapid progress in motorization and critical mixing of traffic flow;Drastic decline of public transport;Fast increase of investment on traffic and sig

7、nificant achievement in infrastructure construction;In 1990s,urban sprawl has led to massive expansion of road,ground public transport and rail transport,in comparison with those in 1980s,road length and area have increased by 340%and 430%respectively and road area per capita has increased by 260%;,

8、Urban expansion stage on initial period of motorized traffic,(II),On motorization stage,urban sprawl demands much higher mobility and rapid growth of motorized traffic has promoted the drastic development of high-level urban traffic infrastructure dominated by express and elevated road,express rail

9、and express public transport,and bearing rapid transit.,(III)Stage of traffic motorization,Express Road Network within Fifth Circular Highway in Beijing,The main framework pattern of urban road network has fundamentally established and thus stimulated the growth of individual motorized traffic meanw

10、hile.With the urban sprawl,motor vehicles are increasing rapidly and traffic flow is saturating,urban traffic congestion is emerging gradually,therefore,merely depending upon road construction alone to expand road network supply,the matter of urban traffic congestion could not be solved effectively;

11、on later stage of urban traffic growth,in order to facilitate public travel and improve traffic efficiency,uniformly planning and coordinating the control and guide of trips by all vehicles in a city have become key and critical to the later stage of urban traffic growth.,Urban traffic developing st

13、ock per capita Index of taxi stock per capita Index of public transit passenger volume per capita,Stage IV,The stage of establishing urban road pattern and giving priority to non-motorized traffic(19491980),The City of Beijing has rehabilitated and reconstructed originally backward urban road system

14、 and road traffic condition there has been obviously improved,thus a tessellate road network pattern taking Second Circular Road formed by east-west CHANGAN Street and north-south axis as well as around city wall location as its framework has been preliminarily established.,Case studyBeijing,With th

15、e acceleration of economic growth,public transport reform and developing process in Beijing has been expedited,Metro Line 2 has been completed and opened to traffic and bicycle has become popular,thus a traffic structure giving priority to pubic transit and non-motorized traffic has been established

16、 gradually.Till the end of 1990,volume of passengers by public traffic was 3.398 billion person-times;inventory of non-motorized vehicles was 8.72 million and that of motorized vehicles was 384,400.,Case studyBeijing,2.The stage dominated by public transit and slow-moving traffic(19801990),The proce

18、twork frame pattern consisting of circular highways plus radial roads has been established and thus stimulated the growth of individual motorized traffic meanwhile.The significant feature of this stage is that with the continued urban sprawl,motorized vehicles increase rapidly and the growth of publ

25、),Comprehensive Traffic Planning System,Tokyo has proposed 16 policy goals and 35 strategic measures for building a“world metropolis”in Tokyo Plan 2000,of which Goal 2 is to mitigate urban traffic congestion,improve traffic condition and build a convenient Tokyo;London has taken changing growth patt
