The adherence to speed limits can reduce deaths associated with road traffic injuries (RTIs) by more than a quarter. This study aimed to evaluate the effective factors on the speeding behavior of Iranian taxi drivers around fixed speed cameras.
Telematics devices used in this study collected the location and speed of the vehicles. The units of analysis in this study were trips per camera, including 2.5 km before and after each camera. Linear regression analysis was used to identify kangaroo driving (KD), defined as trips with a significant V-shape in speed distribution around the camera. In the clustered camera zones, cameras were placed at regular intervals of approximately 3.5 km.
A total of 93,160 trips were recorded from 13,857,443 data points. There was an inverse association between drivers' age and KD with an odds ratio (OR) of 0.98 (95% confidence interval: 0.98-0.98). The intercity trips had a substantially higher probability of KD than urban trips (OR: 4.94 [4.73-5.16]). The tendency of drivers toward KD during the daylight hours vs. nighttime was significant for both urban (OR: 1.15 [1.06-1.25]) and intercity (OR: 1.18 [1.14-1.22]) trips. The 4 -8 a.m. period had the highest chance of KD in both urban (10.71% [7.41-14.53]) and intercity (44.13% [41.18-47.09]) trips. There was a significant decrease in the odds of KD inside the clustered camera zones (OR: 0.22 [0.20-0.25]).
The heterogeneous occurrence of KD in different locations and times indicates the necessity of evidence-based decision-making in urban planning to improve safe driving behaviors. The lower occurrence of KD in clustered camera zones could be a practical key to the effective control of speeding behaviors by helping in the efficient placement of cameras through sustainable development of cities and roads.
遵守限速规定可以使与道路交通伤害（RTI）相关的死亡人数减少四分之一以上。本研究旨在评估影响伊朗出租车司机在固定速度摄像仪附近超速行为的因素。
本研究中使用的远程信息处理设备收集了车辆的位置和速度。本研究的分析单位是每台摄像机的行程，包括每台摄像机前后 2.5 公里。线性回归分析用于识别袋鼠驾驶（KD），定义为在摄像机周围速度分布呈显著 V 形的行程。在集群摄像机区域，摄像机以大约 3.5 公里的规则间隔放置。
从 13857443 个数据点中记录了 93160 次行程。驾驶员年龄与 KD 呈负相关，优势比（OR）为 0.98（95%置信区间：0.98-0.98）。与城市行程相比，城际行程发生 KD 的可能性要高得多（OR：4.94 [4.73-5.16]）。与夜间相比，白天驾驶员 KD 的倾向在城市（OR：1.15 [1.06-1.25]）和城际（OR：1.18 [1.14-1.22]）行程中均具有显著意义。城市（10.71% [7.41-14.53]）和城际（44.13% [41.18-47.09]）行程中，4-8 点发生 KD 的可能性最高。在集群摄像机区域内，KD 的可能性显著降低（OR：0.22 [0.20-0.25]）。
KD 在不同地点和时间的异质性发生表明，在城市规划中需要基于证据的决策来改善安全驾驶行为。集群摄像机区域 KD 发生率较低可能是通过可持续发展城市和道路来有效放置摄像机，从而有效控制超速行为的一个实用关键。
