摘要

在美国,道路节食提供了一种降低交通速度和促进替代出行方式的手段。在整个新泽西州,大约有50个现有的道路节食计划,还有更多的计划。虽然研究表明,道路瘦身可以提高安全性,但没有找到明确的方法来衡量它们对交通流量的长期影响。本文通过商业匿名探测车(APV)速度数据、年平均日交通量等因素,探讨了应用智能交通技术量化长期拥堵变化的一些新的和现有的手段。两个案例研究用于评估拥堵性能指标,分析了800万APV速度记录。虽然有许多变量需要考虑,但这项初步研究为评估道路节食前后对交通流量的影响建立了一个基础措施。

Measuring congestion at road-diet reductions using probe vehicle data
Road diets provide a means to reduce traffic speeds and promote alternative travel modes within the United States. Throughout the state of New Jersey there are approximately 50 existing road diets with more planned. While research has shown that road diets improve safety, no defined means to measure their long-term impact on traffic flow were found. This paper explores some new and existing means for applying intelligent transportation techniques to quantify long-term congestion changes through commercial anonymous probe vehicle (APV) speed data, the annual average daily traffic and other factors. Two case studies are used to evaluate congestion performance metrics, analysing 8 million APV speed records. Although there are a number of variables to consider, this preliminary research establishes a base measure for evaluating the pre- and post-road-diet impact on traffic flow.
