交通事故處理時間特性及警力數推估之研究

國內目前沒有詳細、且完整的交通事故處理時間資料，且缺乏交通事故處理警力數的分析方法，不僅無法評量各警察單位及基層員警處理事故績效，亦無法進一步計算事故處理所需警力。本研究之主要目的在於利用完整之交通事故處理時間資料，嘗試依據事故發生與事故處理時間特性，研擬處理事故之專業交通警力數的推估方法。桃園縣警察局自民國89年3月開始採用的自動顯示位址報案系統（Automatic Location Identification Using ISDN; ALUI），勤務中心接到民眾110報案時，可記錄各案類、時間、地點、內容、通報處理時間及結案時間等完整資料。本研究以該完整之報案記錄資料為基礎，分析得各類交通事故之處理時間特性，以及不同時段事故發生特性，並且發現各時段之事故發生間距時間均為指數分配。本研究進一步研擬事故處理警力數分析方法與步驟，經以桃園縣為例，計算得基礎警力為21人，督導警力4人，合計25人。本研究之成果可提供作為設計或檢討修正交通事故處理警力時之參考。

In Taiwan, complete and detailed data on the service time for traffic accident has not yet been compiled, and there is no adequate method to determine the policemen required for road accidents. Not only it is impossible to assess the efficiency of the service policeman in charge of the accidents, but also it is impossible to determine the required manpower to serve for traffic accidents. The main purpose of this paper is to analyze the service time on the basis of complete accident events to describe a calculate procedure of police manpower determination. The Taoyuan Police Bureau has used Automatic Location Identification Using ISDN (ALIUI) since March 2000 to automatically demonstrate all calls to 110 for police help or service. This system can record data including type, time, location, contents, time span of announcement for service and time to close the case, etc. This paper analyzes the accident data from ALIUI system, shows up the characteristics of handling time and occurrence interval. It is found that accidents happened in different time periods are all distributed as exponential distribution. In the case study of Taoyuan county, this paper calculates that the police personnel required to respond to traffic accidents is 25 policemen which including 21 policemen required to handle traffic accidents and 4 supervisors. The results of this paper could be referenced for designing or modifying the personnel allocation for accident handling.
