Ryosuke A., Keiichi H., & Yasuhiro M. (2018). Data Analysis on traffic accident and urban crime: A case study in Toyota city. International Journal of Transportation Science and Technology, (January 2018), Vol. 7, no. 2, pp 103 -113. https://www.sciencedirect.com/science/article/pii/S2046043017300631

Problem:

Prior to the research conducted by the authors of the paper, urban safety issue on crime and traffic accidents have been discussed separately in most cities in Japan. The authors believed that both issues are related with the physical design and infrastructure construction of a city, and therefore should have some common factors. They conducted the study to deal with urban safety in terms of crime rate and traffic accidents and their relationship with urban design.

Technical Solution:

·         GIS

·         Correlation Analysis

·         Regression Analysis

Datasets Used:
  • Traffic accidents data for the city of Toyota from 1996 - 2012
  • Data on criminal offenses such as murder, robbery, arson, rape, assault, injury, scam and theft from 1996 - 2012
  • Data on social indicators such as population, public facilities like hospitals and shops, road infrastructures, and land use for Toyota city from 1996 - 2012

Outcome:

Prefectural roads length has significantly positive effect in reducing both traffic accidents and urban crimes. Factors such as the number of public facilities, category 1 residential zone and category 1 medium to high rise oriented residential zone led to an increase in traffic accidents and daily-life crimes in the community streets. The authors from the result of the study suggest that in urban planning and urban management, the balance among the different highways, roads and streets when making the road planning, locating the public facilities and the total land use plan should always be considered to reduce the rate of traffic accidents and crime rate in Japan.

Issues that arose:

The total number of elementary schools and districts used in the study used reflects the number available as at and before 2012. The number of schools and districts have changed since 2015.
