A Study on Integrated Construction of Luzhou Comprehensive Transportation Hub

The target of integrated construction of comprehensive transportation hub is to integrate the traffic resources,achieve butt joint of pan-regional transportation mode,and finally realize the"seamless connection"of the goods and"zero transfer"of the passenger traffic.Relying on the particularity of the geographical location and the convenience of the Yangtze River channel,Luzhou puts forth effort to build a comprehensive transport hub in Southern Sichuan and has made great efforts in traffic infrastructure construction.However,there are still some problems.Combining practice of Luzhou,using the advanced experience of foreign and domestic cities for reference,the paper pointed out that for the sake of constructing a comprehensive transportation hub,we need to build the traffic integration on the basis of the efficiency.Besides,the paper proposed the strategies for construction.

Research on the Innovative Development of China’s Comprehensive Transportation System

The comprehensive transportation system is the intensive development stage of the transportation industry,which has gradually become the mainstream transportation mode in the world by giving full play to the advantages of different modes of transportation,promoting the effective use of resources,saving energy and reducing environmental pollution.Since the beginning of reform and opening up,China has achieved a steady improvement in the quality of transportation and a rapid growth in quantity,and has made remarkable achievements in stimulating economic growth and improving people’s well-being.During the14th Five-Year Plan period,China’s comprehensive transportation development will continue to take into account the basic needs and diversified needs,promote the diversified and high-quality development of transportation services,gradually realize the enjoyment of people’s travels and the smooth flow of goods,and continuously meet the growing needs of the people for a better life.We must follow the general idea of“forcing market entities to take the initiative to compete,guiding the development of emerging industries,cultivating the core carrier that drives the integrated development of transportation services,improving regional transportation coordination capabilities,and comprehensively using cutting-edge technologies”,constantly innovating and making breakthroughs in infrastructure,technological innovation,institutional mechanisms,investment and financing policies,and promoting the innovative development and overall leap of China’s comprehensive transportation.

Optimization Model of Regional Comprehensive Freight Hub Location

An optimization model for the regional comprehensive freight hub location problem was built up from the viewpoint of the minimum cost of freight system. The construction method for regional comprehensive intermodal freight network was put forward, and three constraints of the reasonable and feasible path of the intermodal transport, i. e. , reasonable sequence, reasonable freight distance, and reasonable conversion times, were proposed according to the general concepts of the intermodal freight. Then the method for solving the model was given based on the super network and genetic algorithm. Finally, the model and the solution were verified by case study.

基于时空交互视角的中国综合交通运输绿色效率动态演化趋势

It is urgent and important to explore the dynamic evolution in comprehensive transportation green efficiency(CTGE)in the context of green development.We constructed a social development index that reflects the social benefits of transportation services,and incorporated it into the comprehensive transportation efficiency evaluation framework as an expected output.Based on the panel data of 30 regions in China from 2003-2018,the CTGE in China was measured using the slacks-based measure-data envelopment analysis(SBM-DEA)model.Further,the dynamic evolution trends of CTGE were determined using the spatial Markov model and exploratory spatio-temporal data analysis(ESTDA)technique from a spatio-temporal perspective.The results showed that the CTGE shows a U-shaped change trend but with an overall low level and significant regional differences.The state transition of CTGE has a strong spatial dependence,and there exists the phenomenon of“club convergence”.Neighbourhood background has a significant impact on the CTGE transition types,and the spatial spillover effect is pronounced.The CTGE has an obvious positive correlation and spatial agglomeration characteristics.The geometric characteristics of the LISA time path show that the evolution process of local spatial structure and local spatial dependence of China’s CTGE is stable,but the integration of spatial evolution is weak.The spatio-temporal transition results of LISA indicate that the CTGE has obvious transfer inertness and has certain path-dependence and spatial locking characteristics,which will become the major difficulty in improving the CTGE.
