Abstract

Jobs-housing balance refers to the situations where the employment (work) and housing (house) opportunity are coincided in certain geographical area. This paper aims to examine the impact of jobs-housing balance to traffic safety. In pursuing the above, this paper particularly focuses on modeling the traffic accidents by metropolitan area. The main results are as follows. First, three generalized linear models which are all statistically significant are developed. Jobs-housing balance factors are judged to significantly influence on traffic accidents in all models. Second, among common variables, the housing supply rate is analyzed to impact to decreasing, and economically active population and commuting trip attraction are analyzed to impact to increasing. Hence, the alleviation of jobs-housing mismatch is evaluated to be important. Finally, the jobs-housing and business trip rates in Seoul metropolitan area, and the cross-commuting rate in Busan-Ulsan metropolitan area are judged to be essential to transportation safety policies.

직주균형은 일정한 지역에서 직장과 주거가 일치하는 상태를 의미한다. 이 연구는 직주균형이 교통안전에 미치는 영향을 분석하는 데 그 목적이 있으며, 이를 위해 광역권별 사고 모형 개발에 중점을 둔다. 주요 연구결과는 다음과 같다. 첫째, 통계적으로 유의한 총 3개의 일반화선형모형이 개발된다. 모든 모형에서 직주균형 요소는 교통사고 발생에 유의미한 영향을 미치는 것으로 판단된다. 둘째, 공통변수 중 주택보급률은 사고율 감소, 그리고 경제활동인구비율 및 출근통행 도착량은 사고율 증가에 영향을 미치는 것으로 분석된다. 따라서 모든 지역에서는 직주불균형을 완화하려는 노력이 필요할 것으로 평가된다. 셋째, 수도권에서는 직주비와 업무통행비, 그리고 부산 ‧ 울산광역권에서는 교차통근비에 중점을 둔 교통안전정책이 요구된다.
