Does the construction of an integrated transport network promote urban innovation? A perspective based on the theory of flow space

Transportation infrastructure, which has always been regarded as an important element to promote regional innovation, accelerates factor flows and productivity spillovers. In February 2021, the State Council of China issued the outline of national integrated multidimensional transportation network planning (2021–2050), which proposed that during the 14th Five-Year Plan period, the Yangtze River Delta would speed up the construction of an integrated transport network to serve the dual circulation development pattern in China. However, few studies have systematically investigated the development of integrated transport in the Yangtze River Delta, especially the relationship between transport operating efficiency and regional innovation based on the theory of flow space. This study aims to calculate the integrated transport efficiency of 26 cities in the Yangtze River Delta and analyse the spillover effect of efficiency improvement on urban innovation. The results reveal that integrated transport efficiency is relatively stable at approximately 0.92. We find that the local innovation value would increase by 0.119% with every 1% increase in transport efficiency, and it would exceed 0.26% after introducing spatial factors. The spillover effect on the surrounding cities is significantly higher than that in the cities themselves, and the result is 0.292 under the economic spatial distance weight matrix. These findings will support the construction of the integrated transport network and provide useful references for government decision makers in the Yangtze River Delta.

De rol van de Schelde in het Romeins transportsysteem (50 v.Chr. – 410 n. Chr.)

Archaeological sources make it impossible to deny that rivers served as pathways in the past. Conversely, the role of inland waterways in the Roman transport economy of northern Gaul has received little scholarly attention. This paper introduces a historical archaeological study of the transport network of the Roman-era Scheldt basin (presentday north-western Europe), with an emphasis on the role of waterways. As a starting point, this study works from the hypothesis of an integrated transport network, in which rivers, roads, and seaways link up to form a single system.

FEASIBILITY OF INTEGRATED TRANSPORT NETWORK MODEL IN LITHUANIA

Availability of up-to-date and detailed spatial data on transport networks is very important for sustainable development. As Directive 2007/2/EC of 14 March 2007 establishing an Infrastructure for Spatial Information in the European Community (INSPIRE) targets transport networks data as one of the first priority data themes to be harmonized across Europe, the specification for transport network dataset has been developed and adopted as guidance document for all Member States. The specification provides a common model for road, rail, air, water and cable transport networks and related infrastructure. Integrated transport network database can be used for routing of vehicles, taking into account all limitations of the road network, for transport planning, emergency services. In order to achieve the benefits related to common use of up-to-date information and to interoperable data for these tasks, all transport network elements must be accurately mapped in a consistent logical network. Unfortunately, in Lithuania there is no single continuous and extensive spatial data set (geographic database) of transport networks. The authors analysed the possibilities of building joint INSPIRE databases from different transport datasets, and indicated the best data sources for road and railway transport, as well as actions of improvement have to be taken. The research and successful experiment has showed that the more extensive INSPIRE transport data model can be implemented using ArcGIS data model. This concept and the model will serve as an important prop for development of policy of national and transboundary spatial data integration in countries with similar situation. INSPIRE implementation guidelines are compatible with national interest and must be followed, but technical feasibility and cost-benefit considerations must be taken into account.

Analysis on Coal Transportation Network Invulnerability Based on Edge Failure

Coal transportation network is mainly integrated transport network of rail, road and waterway transport modes composed. Transport routes play a crucial role for transport networks normal operation. This paper combine with the definition of coal transportation network invulnerability based on edge failure and attack strategy, proposing invulnerability assessment method, combining with China's coal transportation network to analyze network invulnerability in case of side failure.
