Abstract Traffic congestion has become a bottleneck problem restricting the high-quality development of mega cities like Beijing. At present， the main challenges faced in terms of development of urban transportation in Beijing include the following aspects： the separation of employment and housing is serious， thus forming large-scale tidal traffic； the efficiency gap of the transportation system is relatively large； with a relatively low sharing rate of public transport， the level of green transport needs to be improved； and the end traffic service level is low. One of the main causes of urban traffic congestion in Beijing is the unreasonable mode of urban land use and the serious disconnection between the traffic system and land use. Therefore， great efforts should be made to optimize land use， and promote the deep integration of urban land use and transportation system based on the concept of TOD. At the macro level， the urban agglomeration on the track should be built by relying on the rail transit corridor. At the meso level， the urban agglomeration can be built with the comprehensive transport hub or rail station cluster as the core so that the spatial layout， functional structure and development intensity of the metropolitan area and central urban area will be optimized and the problem of excessive urban congestion and urban function concentration solved. At the micro level， the 5-10-15 minute life circle can be built with the rail station as the core. Thus， with the above basic unit of urban planning and design of eco-city and green transport， the paper puts forward optimal allocation scheme to improve the TOD life circle life service facilities.
