Resolving the property right of transportation emissions through public–private partnerships

The application of public–private partnerships (P3’s) in the transportation sector has grown in popularity worldwide. Despite this important shift in the provision of transportation service, there are clear gaps in knowledge about the impacts of P3 projects, especially on emissions from transportation systems as a whole. Not only should policy makers evaluate the emissions impacts from P3 projects, but they should also think about innovative models that address or charge for emissions into P3 contracts. This addition to P3 contracts could provide a new solution to the long-existing property right paradox: who owns (is responsible for) emissions from transportation systems? This study attempts to fill the research gap by analyzing these innovative models. Using the road network of Fresno, California, as our case study, we offer a number of interesting insights for policy makers. First, average peak emissions costs range from 1.37 cents per mile (the do-nothing case) to 1.20 cents per mile (profit-maximizing cases) per vehicle. Although emissions costs from the P3 projects are lowest for the profit-maximizing cases, the system-wide emissions costs of these cases are highest because of spillover effects. Second, charging project owners for the emissions costs of P3 projects is not an effective way to reduce emissions or the total costs of travel, especially on a VMT basis. Instead, the public sector should implement emissions-included social cost-based price ceilings. When employing these limits, project owners could still be charged for the emissions costs. Finally, using total travel time as the only objective function for evaluating P3 projects can be misleading. Several P3 projects have shown better outcomes using total travel cost with the inclusion of emissions and fuel consumption costs, instead of using total travel time as the only objective function.     

企业科技创新与知识产权制度建设

信号交叉口右转机动车与行人和非机动车冲突研究

研究的主要内容为:未设置右转专用相位的信号灯控制道路交叉口右转机动车流与行人和非机动车的冲突行为,包括冲突数据的采集和提取、右转车流受到干扰前后速度与过街时间对比分析以及机非冲突速度-距离模型。以现实交通数据为基础,通过软件提取右转机动车与行人和非机动车冲突数据,建立标准统一的冲突数据库,以此为基础对比分析右转车流正常行驶状态和受到干扰情况下通过道路交叉口时的车速和过街时间,并建立右转车辆距离机非冲突点不同位置时所对应不同速度的统计模型。研究结果对右转专用相位设立标准的建立和相应信号配时方案的设计具有一定的工程指导意义。
