The safe and equitable accommodation of pedestrians in urban road infrastructure design and traffic engineering

汽车碰撞每年给加拿大经济造成630亿美元的损失，占该国国内生产总值（GDP）的5%。 行人碰撞占该国所有道路相关死亡人数的13%，每年给经济造成20亿美元的损失。 这种情况在美国（和许多其他国家）也很相似，行人占所有道路相关死亡人数的12%，占该国GDP的很大一部分。 因此，在城市道路基础设施设计和交通工程中，行人的安全容纳已成为当今许多城市面临的关键问题之一。 此外，随着人口老龄化，行动能力、视力和体力受损的情况变得普遍，这可能转化为交通基础设施的无障碍限制。

Motor vehicle collisions cost the Canadian economy $63 billion each year, or five percent of the country's Gross Domestic Product (GDP). Pedestrian collisions, which account for 13 percent of all road-related fatalities in the country, cost the economy $2 billion per year. This situation is similar in the U.S. (and many other countries), where pedestrians account for 12 percent of all road-related fatalities and a large component of the country's GDP. As a result, the safe accommodation of pedestrians in urban road infrastructure design and traffic engineering has become one of the critical issues facing many cities today. Furthermore, as the population ages, impairments to mobility, vision and physical strength become prevalent, which can translate into accessibility limitations to the transportation infrastructure.
