为大型车辆盲区制定 "直视 "评级的举措

(2022年6月13日）根据正在制定的新的 "直视驾驶室设计 "标准的支持者，卡车、公共汽车和其他大型车辆的司机需要能够看到 "弱势道路使用者"，如行人。

Together for Safer Roads通过其全球车队安全领导委员会，正在与美国交通部沃尔普中心和TSR成员（如Republic Services）合作，使直视驾驶室设计成为美国的车队行业标准。

该倡议将为车队经理和运营商提供数据和分析，说明车辆在驾驶盲区方面的安全程度或危险程度，包括制定车辆评级标准和建立这些评级的数据库。

根据该公告，直视驾驶室可以减少或完全消除司机的盲区。该组织说，目前，美国现有的绝大多数商用卡车都不提供直视功能，"尽管据估计，每年500多起涉及低速行驶的大卡车的行人和骑车人死亡事件中，有四分之一可以通过直视驾驶室来预防。

Developing Direct Vision Ratings

TSR aims to make direct-vision cab design the standard by showcasing the benefits of a direct vision standard and self-certification process.

TSR plans to partner with fleet leaders to pilot the direct-vision rating standards and initiate the self-certification process to demonstrate truck safety. Its goal is for fleets to make the standards and certification an industry best practice, with supporting research shared across public and private sector fleets to prove the benefits of direct vision.

The standard and certification are built on research from the Volpe Center, whose mission it is to address the nation?s most pressing and complex transportation challenges. It will introduce new tools such as the Volpe Center?s ?View? app (Visibility in Elevated Wide vehicles), a smartphone app that fleets can use to measure blind zones on their vehicles.

Together for Safer Roads and the Volpe Center are partnering to use the View app to assess commercial trucks and create a database of vision ratings for dozens, if not hundreds, of models.

View is a low-cost web application prototyped by students at the Olin College of Engineering, who were sponsored by the Santos Family Foundation and worked under guidance from Volpe Center experts. Data for View is gathered with a standard smartphone, a measuring pole, and a camera stand. The web application calculates a direct vision rating based on the visible space near the truck cab.

In 2018, the Volpe Center, Together for Safer Roads, and waste disposal company Republic Services convened a demonstration of the View system.

The Santos Family Foundation has also provided grants to the Volpe Center to develop and refine applications that facilitate direct vision assessment for truck and large passenger vehicle cabs.

As part of the standard and certification development process, TSR and the Volpe Center will distribute data and analysis to government regulators, car and truck makers, fleet managers, and drivers to promote the need for direct-vision cabs.

Although several vehicle manufacturers already sell direct-vision cab designs in Europe, few are available to fleets in the U.S. or other parts of the world. TSR intends to show manufacturers the untapped potential for direct vision trucks in the U.S. market and beyond, with work already under way through a public-private partnership that includes organizations such as:

The City of New York, which manages the largest sanitation department in the world and is committed to making direct vision trucks the standard.
TSR member Republic Services, one of the largest waste management companies in the U.S., which is conducting research around changing its procurement specifications to require direct-vision cabs.
The National Waste and Recycling Association, which is participating in TSR-led discussions around direct vision.

该 New York City plan notes that ?large trucks may be configured with cabs that allow the driver the greatest possible amount of direct vision and that minimize the need to rely on indirect vision through mirrors, cameras, and other devices. Truck cabs should be positioned as low to the ground as possible and include glazing that extends as far down on the front and sides as practical ? e.g., fully glazed full-height entry doors similar to those on DSNY collectors. Trucks should be either cab-over-engine design whenever feasible, otherwise with a sloped conventional hood to minimize the front blind spot.”

Protecting ‘Vulnerable Road Users’

TSR’s not the only organization concerned about large-vehicle blind spots that can hide pedestrians, cyclists, and other “vulnerable road users.”

The National Transportation Safety Board has been recommending for years that the National Highway Traffic Safety Administration require both medium- and heavy-duty trucks to be ?equipped with visibility enhancement systems to improve the ability of drivers of tractor-trailers to detect passenger vehicles and vulnerable road users, including pedestrians, cyclists, and motorcyclists.?

In 2019, the NTSB reported that data have shown that large vehicles pose a specific problem for bicycle safety, especially in urban areas where large vehicles operate near bicyclists and other vulnerable road users.

The NTSB examined data from 2014 through 2017 and found that 511 bicyclists were involved in crashes involving transit operations. Among them, 374 bicyclists, or 73%, collided with transit buses. Twenty-three bicyclists, or 6%, died in these crashes.

In 2013, the NTSB report, ?Crashes Involving Single-Unit Trucks that Resulted in Injuries and Deaths,? concluded that onboard systems and equipment that compensate for blind spots and allow drivers of single-unit trucks to detect vulnerable road users could prevent fatalities and injuries that occur in crashes involving single-unit trucks. Such systems and equipment could include enhanced mirror systems or sensors that can alert drivers if there is another vehicle, bicyclist, or pedestrian in the blind spot after the driver activates the turn signal.
