| Urban Transportation can be seen as the city's blood vessels, survival and development of the city foundation, connecting every corner of the city. In recent years, with the constant expansion of our city, people's living standards, the rapid growth of urban population, the urban traffic congestion to face greater pressure, making the city roads exposed many serious problems. In order to alleviate such conflicts, the international city in many countries have carried out evaluation of the status of the road transport network for urban road design and transportation planning to provide an important reference and basis. Therefore, the urban road network status assessment and analysis of science is imminent. Establish evaluation index system of urban road network, road network have been completed the status of scientific and accurate description and evaluation of urban transport system for short-term rehabilitation and long-term planning to provide basis for decision making.This paper uses the theory of road traffic network connectivity to explore the eco-city road network connectivity and characteristics of the content, road transport network in the city constitute the basis of the analysis, using the connectivity index and index and the introduction of transport network of roads connecting evaluation to establish method and system, the center of Hohhot city traffic road network in the road network connectivity were evaluated. This addition to the downtown Hohhot, the grading of the road transport network, but also the four areas of Hohhot, were calculated, respectively, made a comparative analysis further reflects the status of urban road network. According to the results at this stage of Hohhot, the main traffic road network analysis of the problems and put forward countermeasures and suggestions related to the purpose for the development and construction of Hohhot city and urban transport planning to provide a theoretical basis.
