Many megacities in the world, especially Bangkok, are facing severe congestion road traffic and public transport, particularly during peak hours. This situation (a) worsens quality of life, (b) releases emissions causing air pollution climate change, (c) subsequently creates requests for massive investment transport infrastructure, which easily exceed budget’s limit. Instead solving problem by supply-side strategies, applying ICT-based solutions to reform people’s daily activities, commuting...

Roadway area calculation is a novel problem in remote sensing and urban planning. This paper models this as two-step problem, roadway extraction, calculation. extraction from satellite images that has been tackled many times before. proposes method using pixel resolution to calculate the of roads covered images. The proposed approach uses U-net Resnet architectures called U-net++ ResNeXt. state-of-the-art model combined with efficient post-processing improve overlap ground truth labels....

The often-discussed issue of parental escorting children to school and its potential disruption traffic flow has been extensively examined in the literature. Still, specific effects congestion remain understudied. To fill this gap, study addresses impacts trips on congestion. An agent-based model is applied simulate various scenarios assess their impact. Our findings indicate that speed without higher during peak hours by around 8% average travel time city reduced significantly. We examine...

Market forces and/or planned intervention in many metropolitan areas are transferring urban form from mono-centric to more dispersed or, poly-centric structure where firms cluster outside city center and location trip patterns tend vary amongst cities. As study area, distribution of employment, related commuting residential preferences Tokyo area have been investigated by grouping zones into four tiers analyzing associated lengths, mode shares employment destination zonal preference...

Among the benefits of high-speed rails (HSRs) discussed from various aspects, indirect may contribute to medium- and long-term economic impacts such as an increase in service supply gross regional product (GRP). In order estimate impacts, we modeled I/O–spatial interaction by combining inter–industrial transactions shown on I/O table with geospatial distance decay mass through passenger transportation. addition, a part benefits, were evaluated model applied Mumbai–Ahmedabad High-Speed Rail...

This study investigates how transport accessibility was associated with the accumulative number of confirmed cases COVID-19 and its daily new cases, at prefecture level, in Japan. The analysis conducted month by from January to September, 2020. A gravity model estimated measure a nonlinear regression much is spread COVID-19. Analysis results suggest that Japanese government may need pay sufficient attention lifting various restrictions both activity participation trip making, within cities...

Among the various effects of high-speed rail (HSR), a direct benefit to users has been measured as an increase in gross domestic product (GDP) by conventional cost–benefit analysis (CBA), which was institutionalized U.K. In recent years, importance capturing indirect benefits non-users also broadly discussed. The HSR can mainly be classified into two perspectives: regional economy and personal quality life (QOL). this study, we modeled mutual enhancement between those analyzed...

One of JST and JICA's technical cooperation projects, ”Smart Transportation Strategy to Realize Thailand 4.0,” aims reduce traffic congestion simultaneously achieve low carbon emissions improve citizens’ quality Life (QoL). To this goal, it is necessary develop an AI-based system that allows users select a combination transportation modes meets the various needs people all ages genders, realize evaluation QoL from images required. The project suggests how when moves some point another...

This study aims to evaluate the effects of corridor formation where population and urban facilities gather intensively public transport on travel convenience. A potential-type accessibility index is applied. Three scenarios are developed: A) Increase service level routes along corridor, B) Equal increase among whole areas C) Land-use development in area. The results indicate that major system brings higher equality. Additionally, brought by land-use area with system.

ASEAN各国において，低炭素交通政策に関する長期行動計画の実施により削減されるCO2排出量を評価するためのツールを開発した．このツールは，ASEAN各国における長期行動計画提案を目的とした研究プロジェクトの一環として開発したものであるが，将来的には現地の行政官・研究者等に提供し，独自の長期行動計画を構築するために活用されることを想定して，開発を行った． ツールには，車両の燃費や各種燃費の排出係数等の各種データの他，複数の政策パッケージとそれらの導入効果がプリセットとして格納されており，ユーザーは自国に適した政策パッケージを選択し，その導入開始年や導入効果が最大になるまでの期間を選択することで，容易にCO2排出量削減効果を評価することが可能である．

本研究は、鉄軌道線廃止後の代替交通網整備の検討方法について示唆を得ることを目的としている。2006年10月に廃止となった桃花台新交通桃花台線(愛知県小牧市)を対象として、その廃線前後の沿線における交通利便性変化を、土地利用を考慮した評価が可能なポテンシャル型アクセシビリティ指標を用いて評価した。その結果、代替公共交通網により名古屋市方面への交通利便性は維持されているものの、小牧市内へのそれは大きく低下していることが明らかとなった。この結果と、独自に実施した廃止に伴う住民の交通行動変化に関するアンケート調査結果とを比較したところ、おおむね合致していることがわかった。このことから、鉄軌道廃止後の公共交通網検討のための評価指標として、アクセシビリティ指標を用いることが可能であると考えられる。

This paper examines an application of central-lane bus system, Nagoya Key-Route-Bus, on purpose revealing its medium and long term effects transport. Analytical results confirmed: 1) the less ease being exposed by other vehicles road, higher operation speed more punctuality 2) good number users independent population distribution along route 3) no decrease in total passenger-km corridor despite reduction lanes designated for automobile 4) trip time, considering longer access time to stops...

As a means of controlling vehicle brake pressures for varying axle loads and/or decelerations, link-less deceleration sensing valves are being used in addition to fixed split point and link type load proportioning valves. These optimizing the ratio front-to-rear wheel retarding forces full range loadings decelerations thereby improving balance stability. This paper describes valve designed developed passenger cars light trucks. Also, included dynamic simulation test results.
