ระบบสารสนเทศภูมิศาสตร์เพื่อการศึกษา การกระจายทางพื้นที่ของอาชญากรรม / วรยา ไทพาณิชย์ = Geographic information system for the study of spatial distribution of crimes / Woraya Thaiphanich
This research applied Geographic Information System (GIS) exploring crime pattern on road and landuse map in the Bang Sae Police Station area and statistic methods analyzing socio-economic factors involved. Both crimes of violence and crime against property were clustered in the risk area, i.e. Merry King Department Store, Jatujak weekend market, Mochit bus terminal and along the main road, Phahonyothin Rd., Pradiphat Rd., and Sutthisan-winitchai Rd. Nearest neighbor index confirmed cluster patterns of all crime types. Chi square was used to statistically test the association of crime patterns and six variables of socio-economic factors. Only time social variable was found significant. There is no statistic significance of relationship of crime and an economic factor, the number of coroparates end while economic crisis. The cluster crime patterns and significant time ranges were put into the final map. The map showed cluster crime area and roads during six time activities period 24 hours a day, 4 hours each. This result leads to suggest changing police patroling period. During 17:00-21:59, Merry King department store, Jatujak weekend market, Mochit bus terminal should be frequently patrolled. Awareness during 21:00-24:59 at Sutthisan-winitchai Rd. was more likely to prevent crimes of violence. People should avoid places and time period as previously described to reduce chance of being victims. Moreover, it is found that the after work period, 17:00-21:59, was the most frequently crime time. The probability of being risk in that period was further studied by logistic regression. It resulted in percentage of chance in which a crime was likely to occur in such a period. Male and female had equal opportunities of being victims. People should be in more crowded area due to the less probability. The chance of crime in commercial area was the same as other landuse area.
