A Factors Analysis on Crime Occurrence in School Zone

Chiaki Matsunaga; Aya Miyazaki; Tomonori Sumi

(1)研究の背景 児童が巻き込まれる事件・事故はここ数年で急増して おり,既存の調査によると,多くの小学校区で四割前後 の子供が高学年になるまでに犯罪の危険に遭遇している ことが報告されている.これらの犯罪に遭遇する場 所の半数以上は学校周辺の路上であり,登下校中の児童 を狙った犯罪が多いことの現れである.このように登下 校時の児童の安全確保が急務とされる現在,警察や自治 体,学校,PTA,地域住民などにより様々な取り組みが なされている. 一方近年ではまちづくり・都市計画レベルでの防犯対 策が注目され始めている.これは防犯環境設計(CPTE D)という,「物理的環境を適切に設計・利用すること で,人の心理や行動に影響をおよぼし,未然に犯罪の発 生を防ぐ手法」に基づくものである.CPTEDは条件 が揃えば犯罪を遂行する機会犯罪などに有効とされ,そ のことから子どもを対象とした犯罪の防止に対しても効 果的であるとされる.また,児童対象犯罪の多くが路上 で発生していることを考えると,登下校時の児童の安全 を論じる上では道路の構造や交通量を考慮した防犯対策 を無視することはできないと考える. 以上より,CPTED手法に基づいた安全・安心な通学 路設計のためには具体的かつ定量的な知見を得ることが 重要であると考え,本研究の目的とする.

A pedestrian chooses the highest utility action of conditions in the streets and individual attributes, such as move distance, vehicles penetration, stores, and a walk form, when passing through a streets. Moreover, the judgment changes with target existence. So this paper, the pedestrians flow model considering road conditions in shopping streets was-assumed, and the parameters in a model were presumed from actual investigation. Consequently, the good model was obtained. Furthermore, factors comparison and the simulations of walk action were performed based on this parameters.
