Abstract

The rising number of traffic collisions in developing countries has sparked concern due to a lack of understanding and mitigating measures. To grasp their behavior and contribute to the quantitative assessment of road safety, the adaptation of predictive procedures for estimating the frequency and type of crashes, created in the United States and contained in the Highway Safety Manual (HSM), has been chosen. The applicability of these procedures in developing countries with different conditions depends on their adaptation to the environment, which is the objective of this work—to assess the applicability of the predictive method of the Highway Safety Manual (HSM) for urban intersections under conditions unique to Colombia. Signalized intersections in Medellín were selected, collecting data on crash occurrences, vehicular volumes, and geometric characteristics to create simulation scenarios to evaluate the applicability of the predictive method. Calibration Coefficients for the HSM's predictive method at three- and four-way intersections were calculated using the Crash Prediction Module (CPM) of the IHSDM software, concluding shortcomings in the application and transferability for Colombia and likely for other developing countries.
预测高速切削方法在哥伦比亚城市信号交叉口适用性评价
由于缺乏对交通事故的了解和缓解措施,发展中国家日益增多的交通事故引起了人们的关注。为了掌握他们的行为并有助于道路安全的定量评估,选择了在美国创建并包含在公路安全手册(HSM)中的预测程序来估计碰撞的频率和类型。这些程序在具有不同条件的发展中国家的适用性取决于它们对环境的适应性,这是本工作的目标——评估《公路安全手册》(HSM)预测方法在哥伦比亚独特条件下对城市十字路口的适用性。选择Medellín的信号交叉口,收集碰撞发生率、车辆数量和几何特征的数据,创建模拟场景,以评估预测方法的适用性。使用IHSDM软件的碰撞预测模块(CPM)计算了三路和四路交叉口高速公路预测方法的校准系数,总结了哥伦比亚和其他发展中国家在应用和可转移性方面的缺点。
