This laboratory researches the following themes in the pursuit of the ideal state for a safe, convenient,
comfortable, and environmentally-friendly urban structure and transport systems that is in unison withregional society, and how it might be realized.

Theme 1The eﬀective and eﬃcient realization of traﬃc safety management thatlies at the center of improving the road traﬃc environment demandsa scientiﬁc understanding of the risks posed by traﬃc accidents.
Our laboratory is aiming to construct a traﬃc safety management
method that uses not only traﬃc accident statistical data, but also
traﬃc big data such as drive recorder data, vehicle probe data, andthree dimensional road space data. Our approach is focused on
Aichi Prefecture and Toyohashi City, and includes the constructionof an accident risk statistical model, the evaluation of accident risks
Extraction of rat-run traﬃc from car probeby location and type of accident and an analysis of their causes, thedata
observational survey, analysis and construction of a simulation modelfor detailed traﬃc ﬂows at speciﬁc accident risk points, and the proposal and evaluation of traﬃc safetymeasures based on all of this information.

Local public transport network planning considering taxi mode
Theme 2
It is important to consider ideas that makeuse of taxi mode in local public transport
network. Taxi mode is an individual anddoor to door transport system and has theadvantage of being able to meet the diverse
needs which mass transit systems such as
railways and buses could not meet. Ourlaboratory analyses the actual situation andof taxi trips and the mechanisms of the use
taxi mode based on digital daily log data
Distribution of departure and arrival points of taxi trips in Toyohashi (Left:and evaluates several policies that make

use of taxi mode as a local public transport
network through simulations and so on.

Theme 3Future public service demand estimation for sustainable urban structure
It is concerned in the local government it becoming severe to oﬀer
public service at the same level now by annual revenue decrease
under a population decline and aging society. Emerging pressures
for more eﬃcient and eﬀective public management require morerational approach in forecasting future demand for public services
before such problems will be actualized. Our laboratory develops
the method to estimate the future distribution of population orhouseholds and grasp the change of urban service demand
including transportation using urban model considering interaction
between land use and transportation, in particular, microsimulation
model. And we evaluate policy measures for sustainable urban
Analysis framework of urban model consideringinteraction between land use and transportation
structure, such as encouraging relocation policy to , improving or
rebuilding of public transport network.
