Investigating Effects of New Vehicle Technologies on Highway Safety from Transition to Full Implementation

公路系统为旅客和货物提供了最重要的运输方式。道路基础设施的规划和设计是一项相对简单的任务，直到20世纪初引入机动车辆，这需要道路设计和建设的重大变化。然而，解决日益出现的安全问题的道路设计指南的发展比实际需要落后了大约半个世纪，在加拿大甚至更晚。通信和计算技术的最新进步通过开发和部署两种独立的新车辆技术，使车辆设计走上了重大革命性变化的道路：联网车辆（cv），车辆可以相互通信并与公路基础设施通信，以及自动驾驶车辆（AVs），也被称为自动驾驶车辆。虽然一些自动驾驶/自动驾驶技术已经在道路上部署，但估计最早将在2020-2025年大规模实施。随着这些技术的全面实施，以及随着它们进入市场，预计将带来显著的好处，包括减少拥堵、降低燃油消耗和车辆排放、提高机动性、大幅减少碰撞。虽然自动驾驶/自动驾驶技术是为了在现有的道路基础设施上运行而开发的，但要实现这些新技术的全部优势，肯定需要对道路进行改造。

The highway system provides the most important mode of transportation for passengers and goods. Planning and design of the road infrastructure was a relatively simple task until the introduction of motorized vehicles in early 1900s, which required major changes in road design and construction. However, the development of road design guidelines to address arising safety problems was around half a century behind the actual need and was even later in Canada. Recent advancements of communication and computing technologies have put vehicle design on the path of significant revolutionary changes through the development and deployment of two separate new vehicle technologies: connected vehicles (CVs), where vehicles can communicate with each other and with the highway infrastructure, and autonomous vehicles (AVs) which are also known as self-driving vehicles. While some CV/AV technologies are already deployed on the road, estimates put wide-scale implementation as early as 2020-2025. Significant benefits including reduced congestion, reduced fuel consumption and vehicle emissions, improved mobility, and considerable reduction of collisions are expected not only with the full implementation of these technologies but also as they penetrate the market. Although CV/AV technologies are developed to operate on the existing road infrastructure, road modifications will certainly be required to realize the full benefits of these new technologies.
