This research pertains to urban infrastructure and institutional support for low carbon transport systems, particularly as they relate to electric vehicle utilization.
As approaches to the realization of such systems, we study (1) environmental taxes, parking deposit systems (PDS; studied by the project leader and others as a new approach to road pricing under a grant from the Ministry of Land, Infrastructure, Transport and Tourism), and other pricing schemes to encourage switchovers to next-generation vehicles and discourage the use of conventional vehicles, (2) locational planning for recharging stations for next-generation vehicles together with promotion of renewable energy source utilization, and (3) policy packages comprised of traffic demand management (TDM), intelligent transport systems (ITS), light rail transit (LRT), electric vehicle (EV) car sharing, and rearrangements of urban spaces.

項目1

Electric vehicles (EVs) and other next-generation vehicles, together with traffic demand management (TDM) techniques, are noted for their efficacy in reducing the carbon footprint of transport systems. In this research, we examine policy packages—containing, measures to promote the utilization of next-generation vehicles, introductions of TDM or EV car sharing arrangements, and rearrangements of urban spaces (provision of dedicated lanes, etc.) to give priority to non-polluting vehicles—together with the urban infrastructure and institutional support necessary to implement them. Specifically, our proposals entail an assortment of measures within a policy package, a reconfiguration of pricing schemes (environmental taxes, parking deposit systems (PDS, proposed by the lead researcher as a new approach to road pricing)), and the system design or consensus building methods to make it all possible.

This research pertains to the modeling of lifestyle/transport behavior, as useful for (1) predicting patterns of vehicle ownership and mobility (i.e., selection of destination, method, and route), (2) forecasting the effects of pricing policies (environmental taxes, parking deposit systems (PDS) to encourage next-generation vehicle utilization, traffic demand management (TDM), light rail transit (LRT), and similar initiatives), and (3) proposing comprehensive policy packages (consisting of pricing, TDM, intelligent transport systems (ITS), LRT, spatial rearrangements, etc.) most effective for reducing carbon dioxide emissions. Here, we examine power supply and demand patterns entailed by next-generation vehicles, methods in which renewable energy sources can be utilized to accommodate them, and various system design measures to address related issues, problems, and power supply concerns. We also conduct concrete system design for package components such as road/vehicle-related taxation, environmental taxes, and pricing schemes (PDS, etc.), and furthermore propose methods for achieving societal consensus toward the implementation of the taxes and systems we propose.

Low carbon transport systems contribute to international efforts to forestall global warming. Here, we examine information exchange and overseas development toward the realization of such systems through joint workshops including the Shanghai Tongji Urban Planning & Design Institute (TJUPDI) and the Japan-China Joint Seminars on City and ITS.

Japan-China Joint Seminar on Low Carbon Urban Transport Systems and EVs

Japan-China joint seminar on Low Carbon Urban Transport Systems and Electric Vehicles was held on February 28th, 2012, in Tsinghua University, China.
There were in total nine presentations given by both Japanese and Chinese researchers.
