Comparison among Tokyo,Shanghai and Chukyo Metropolitan Region Rail Transits and Some Inspiration

Based on the analysis and comparison of Tokyo,Shanghai and Chukyo metropolitan region rail transits,this thesis brought forward that the length scale of rail transit network in China mega-cities should be great than 2 000 km,and we should attach importance to the planning and building of the rail transit in the outer part of city's inner loop,and the planning of rail transit network should adopt combinative mode of radiation and circle line.Otherwise,it also brought forward the calculation formula of the layout lengthof rail transit and pointed out that some inspirations must be absorbed in planning,designing and runing the suburb's rail transit.The apocalypses including inner and outer loops should adopt different rail transit system,it should adopt the rail transit infructures different from downtown's,running of the suburb train should accord with the character of passenger flow,the building of suburb railway should well deal with the cooperation problem,etc.
