ABSTRACT

Increasing timber transportation safety is essential to the timber harvesting and forest products industries. Log truck weight limits in the US South are lower than in other US regions. North Carolina and Virginia increased their gross vehicle weight limits for log trucks from 38,102 kg to 40,823 kg in 2012 and 2015, respectively. Log truck crash reports were collected from state authorities in North Carolina and Virginia for crashes occurring between 2009 and 2019. Log truck crash rates, contributing factors, crash locations, and vehicle condition were analyzed to identify opportunities to improve safety and evaluate the relationship between log truck crashes and changes in weight limits. Between 2009 and 2019, log truck crashes per million tonnes of timber harvested increased by 134% and 29% in North Carolina and Virginia, respectively. Crash rates were rising before the increases in weight limits and continued to rise afterward. Exceeding safe speed, improper turn, and failure to yield the right-of-way were common contributors to crashes in both states. Timber transportation safety may be improved through driver education, better fleet maintenance, and increased use of crash reduction technologies.

美国北卡罗来纳州和弗吉尼亚州增加重量限制前后的原木卡车碰撞事故

摘要

提高木材运输安全对木材采伐和林产品行业至关重要。美国南部的原木卡车重量限制低于美国其他地区。北卡罗来纳州和弗吉尼亚州分别在 2012 年和 2015 年将原木卡车的车辆总重量限制从 38,102 公斤提高到 40,823 公斤。从北卡罗来纳州和弗吉尼亚州当局收集了 2009 年至 2019 年间发生的事故的原木卡车碰撞报告。分析了原木卡车碰撞率、促成因素、碰撞位置和车辆状况,以确定提高安全性的机会并评估日志之间的关系卡车碰撞和重量限制的变化。2009 年至 2019 年间,北卡罗来纳州和弗吉尼亚州每百万吨木材的原木卡车碰撞事故分别增加了 134% 和 29%。在重量限制增加之前,碰撞率一直在上升,之后继续上升。超过安全速度、不当转弯和未能让行是导致这两个州发生撞车事故的常见原因。可以通过驾驶员教育、更好的车队维护和更多地使用减少碰撞技术来提高木材运输的安全性。
