自 2 月以来，Declo 入境口岸发现 1,100 起卡车轮胎问题。
随着州交通部推出价值 120 万美元的检测传感器系统，通过爱达荷州入境口岸的商用车辆的轮胎正受到新的审查。
ITD 商用车服务经理 Craig Roberts 告诉《交通话题》，爱达荷州交通部董事会批准使用未分配的安全改进资金在该州入境口岸安装新的轮胎异常和分类系统。“当有轮胎问题的商用车辆停下来纠正爆胎、漏气或轮胎丢失时，驾驶公众会更加安全，”Roberts 说。“安装 TAC 系统是一种主动的安全方法。”自爱达荷州于 2 月份在 84 号和 86 号州际公路交界处以西 3 英里处的 Declo 入境口岸安装第一套 TAC 系统以来，已检测到 1,100 多个轮胎异常。
“对于所有高速公路使用者来说，在道路上安全行驶非常重要。ITD 正在关注驾驶员和公共用户，确保商用车轮胎状况良好，可以继续行驶，”他补充道。州政府官员在爱达荷州入境口岸检查商用车辆，以确定安全问题。该州入境口岸每年的卡车重量超过 375 万辆。
“TAC 系统安装在道路上，检查半挂卡车轮胎是否有异常和损坏。港口员工可以使用 TAC 数据通知卡车司机轮胎损坏或充气不足，以免造成安全问题，”ITD 解释说。“半挂卡车在高速公路上行驶时爆胎可能会很危险，甚至会致命。”罗伯茨表示，检查遵循联邦停用标准。“如果轮胎气压不足，则需要充气或更换轮胎，然后才能继续行驶。[入境口岸] 将对违规行为发出警告，”他补充道。
ITD 已安排在入境口岸安装新的 TAC 系统，以配合其他施工或维护工作，以尽量减少关闭。以下是预计到 8 月的关闭时间范围。
5 月 28 日那一周：I-84 上的东博伊西入境口岸，双向距离博伊西以东约 11 英里
6 月：I-15 上波卡特洛以南 8 英里的 Inkom 入境口岸将分阶段安装。南行路段将于 6 月完工，而北行路段将于明年在那里的立交建设期间完工。
7 月 15 日当周：刘易斯顿入境口岸位于美国 12 号和 95 号公路交叉口，双向通行
7 月下旬或 8 月初：Sage Junction 入境口岸位于 I-12 上罗伯茨以北 8 英里处，双向通行
8 月：Huetter 入境口岸位于 I-90 上科达伦以西 2 英里处，双向通行
罗伯茨引用了联邦汽车运输安全管理局关于商用车事故中轮胎问题的国家研究。联邦汽车运输安全管理局 2021 年大型卡车统计数据表明，轮胎和制动系统是大型卡车致命事故中最常见的车辆相关因素。
在相关发展中，联邦汽车运输安全管理局的商用汽车路边技术走廊正在与各州合作的一个项目中研究轮胎安全筛查系统的有效性，该项目将由美国能源部的橡树岭国家实验室进行评估。

“利用路边技术识别可能存在部件违规的车辆，从而提高检查过程的效率，这一直是一项挑战。很少有系统能够在不进行目视检查的情况下准确确定车辆是否存在缺陷，包括动态称重、基于红外线的筛查系统以及现在的轮胎安全筛查系统，”联邦汽车运输安全管理局在项目描述中表示。
这项名为“轮胎安全筛查系统”的研究将使用来自合作州的轮胎检查数据和信息来确定轮胎筛查技术是否增加了轮胎违规率，与没有任何高科技系统识别的问题轮胎相比。
“ORNL 之前的任务是确定国际道路动力学轮胎异常分类系统 (TACS) 轮胎筛查系统的位置和有效性，以确定它们的使用方式以及使用该技术存在哪些问题。作为这项任务的一部分，五个州接受了采访，以确定该系统的准确性以及该系统在其州的使用方式。据传闻，所有接受采访的州都对该系统给予了高度评价，称车辆被标记的频率很高，而且非常准确，”联邦汽车运输安全管理局表示。
联邦汽车运输安全管理局将发布一份最终报告，其中包含其调查结果的摘要和
对轮胎安全筛查技术的理想使用情况和未来研究领域的建议。
Idaho Rolling Out $1.2 Million Tire Inspection Sensor System
1,100 Truck Tire Problems ID’d Since February at Declo Port of Entry
Tires on commercial vehicles traveling through Idaho’s ports of entry are coming under new scrutiny with the state transportation department rolling out a $1.2 million system of inspection sensors.
The Idaho Transportation Department board approved using unallocated funds for safety improvement to install new Tire Anomaly and Classification Systems at the state’s ports of entry, Craig Roberts, ITD commercial vehicle services manager, told Transport Topics.
“The driving public is much safer when commercial vehicles with tire issues are stopped to correct blowouts, flats or missing tires,” Roberts said. “Installing TAC systems is a proactive approach to safety.”
More than 1,100 tire anomalies have been detected since Idaho’s first TAC system was installed in February at the Declo Port of Entry 3 miles west of the junction of interstates 84 and 86.
“It is important for all highway users to be safe while on the roadway. ITD is looking out for both drivers and public users by ensuring commercial vehicle tires are in good shape to continue their journey,” he added.
State officials inspect commercial vehicles at Idaho’s ports of entry to identify safety issues. The state’s ports of entry weigh more than 3.75 million trucks annually.
“TAC systems are installed in the road and screen semi-truck tires for anomalies and damage. Port employees can use the TAC data to notify truck drivers of damaged or underinflated tires before they cause a safety problem,” ITD explained. “A tire blowout on a semi-truck traveling at highway speeds can be dangerous, even deadly.”
Roberts said the inspections follow federal out-of-service criteria. “Tires will need to be inflated if just low on air or replaced before being allowed to proceed. The [port of entry] will issue warnings for the violations,” he added.
ITD has scheduled new TAC system installations at the ports of entry to coincide with other construction or maintenance work to minimize closures. Below are the expected closure time frames through August.
Week of May 28: East Boise Port of Entry on I-84 about 11 miles east of Boise in both directions
June: Inkom Port of Entry 8 miles south of Pocatello on I-15 will have a phased installation. The southbound side is to be completed in June, while the northbound section will be finished next year during interchange construction there.
Week of July 15: Lewiston Port of Entry at the intersection of U.S. routes 12 and 95 in both directions
Late July or early August: Sage Junction Port of Entry 8 miles north of Roberts on I-12 in both directions
August: Huetter Port of Entry 2 miles west of Coeur d’Alene on I-90 in both directions
Roberts cited a national Federal Motor Carrier Safety Administration study about tire problems in commercial vehicle crashes. FMCSA’s 2021 statistics for large truck stated that tires and brake systems were the most common vehicle-related factors for large trucks in fatal crashes.
In a related development, the FMCSA’s Commercial Motor Vehicle Roadside Technology Corridor is studying the effectiveness of tire safety screening systems in a project with states that will be evaluated by the U.S. Department of Energy’s Oak Ridge National Laboratory.
FMCSA Studies Tire Safety Screening Systems
“Utilizing roadside technology to increase the efficiency of the inspection process by identifying vehicles with potential component violations has been an ongoing challenge. Few systems exist that can accurately determine the presence of a vehicle defect without a visual inspection, including weigh-in-motion, infrared-based screening systems and now tire safety screening systems,” FMCSA stated in a project description.
The study, called “Tire Safety Screening Systems,” will use tire inspection data and information from partnering states to determine if tire screening technology increased the rate of tire violations compared to problem tires identified without any high-tech systems.
“ORNL was previously tasked with identifying the location and effectiveness of the International Road Dynamics Tire Anomaly Classification System (TACS) tire screening system to determine how they were being utilized and what problems existed with the usage of this technology. As part of this task, five states were interviewed to identify how accurate the system was and how the system was used in their state. All the interviewed states had high praise of the system anecdotally, stating that vehicles were flagged frequently and with great accuracy,” FMCSA stated.
FMCSA will issue a final report with its findings that contains a summary and recommendations for ideal use situations and future research areas for tire safety screening technology.
