论文摘要
行人和骑自行车的人是脆弱的道路使用者。与其他道路使用者相比,他们在撞车事故中被杀的风险更大。涉及行人或骑自行车者的致命崩溃百分比高于两种模式进行的总旅行的总比例。由于这种风险,寻找最小化有问题的街头环境的方法至关重要。了解行人和骑自行车的人的交通安全空间模式,并确定具有显着高碰撞风险的危险位置,对于设计可能的对策以提高道路安全至关重要。这项研究开发了两个指标,用于检查建筑环境元素(交叉路口)和崩溃(行人或骑自行车的人)之间的空间相关模式。全球托管商检测到一个区域中的整体连接,而本地托管商可以识别高风险交叉点的位置。为了说明我们的方法,我们采用了这些方法来检查德克萨斯州休斯敦的行人或骑自行车的车辆撞车和交叉点之间的托管模式,我们在许多交叉路口中确定了大幅吸引撞车事故的交叉点。我们还仔细检查了这些交叉点,讨论了可能的属性,从而导致崩溃的高阳性和建议的相应对策。
Pedestrians and cyclists are vulnerable road users. They are at greater risk for being killed in a crash than other road users. The percentage of fatal crashes that involve a pedestrian or cyclist is higher than the overall percentage of total trips taken by both modes. Because of this risk, finding ways to minimize problematic street environments is critical. Understanding traffic safety spatial patterns and identifying dangerous locations with significantly high crash risks for pedestrians and cyclists is essential in order to design possible countermeasures to improve road safety. This research develops two indicators for examining spatial correlation patterns between elements of the built environment (intersections) and crashes (pedestrian- or cyclist-involved). The global colocation quotient detects the overall connection in an area while the local colocation quotient identifies the locations of high-risk intersections. To illustrate our approach, we applied the methods to inspect the colocation patterns between pedestrian- or cyclist-vehicle crashes and intersections in Houston, Texas and we identified among many intersections the ones that significantly attract crashes. We also scrutinized those intersections, discussed possible attributes leading to high colocation of crashes and proposed corresponding countermeasures.
