This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The research objective of this award is to explore how different vehicle classes, such as automobiles, buses and bicycles, interact on large, city-scale transport networks. This is necessary because previous research has been limited to small-scale systems, such as individual intersections, dominated by a single mode -- the automobile. The work will proceed on two parallel fronts. The first will identify the smallest basic component within a multimodal network for which the governing laws of traffic can be scaled-up to the larger, city-wide level. The second will study systematically the cross-modal vehicular interactions that arise on these basic components. The work will involve both theory and experiment. The latter is made possible thanks to agreements that have been reached with decision-makers in various cities, including several cities in the developing world where the need for efficient multi-modal travel alternatives is especially acute. Anticipated outcomes include analytical models that describe how different vehicle classes interact and coexist, and show how to improve network designs and control methods. The research will address the global climate crisis and the rising cost and growing scarcity of oil to help cities embrace greener, more sustainable modes of transport, including public transit, bicycles and walking. The findings will help engineers and planners devise strategies that improve mobility for all urban travelers regardless of the mode they use, and help policy-makers in their efforts to make the greener modes a more viable alternative to automobiles. The latter will benefit the planet; the former the local citizenry. It is expected that benefits will flow in particular to those in society who are least able to own and drive cars. The work will contribute to scientific education because it will support two doctoral dissertations, and its findings will be integrated into the curricula at U.C. Berkeley and perhaps elsewhere.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该奖项的研究目标是探索不同的车辆类别，如汽车，公共汽车和自行车，如何在大型城市规模的交通网络中相互作用。这是必要的，因为以前的研究仅限于小规模的系统，如个别交叉口，由一个单一的模式-汽车为主。这项工作将在两个平行的方面进行。第一个将确定最小的基本组成部分内的多式联运网络的交通管理法律可以扩大到更大的，全市范围内的水平。第二部分将系统地研究这些基本组成部分所产生的跨模态车辆相互作用。这项工作将包括理论和实验两方面。后者之所以成为可能，是因为与各城市的决策者达成了协议，其中包括发展中世界的几个城市，这些城市对高效的多式联运替代方案的需求特别迫切。预期成果包括描述不同车辆类别如何相互作用和共存的分析模型，并展示如何改进网络设计和控制方法。该研究将解决全球气候危机、石油成本上升和日益稀缺的问题，以帮助城市采用更环保、更可持续的交通方式，包括公共交通、自行车和步行。研究结果将帮助工程师和规划者制定策略，改善所有城市旅行者的出行能力，无论他们使用何种模式，并帮助政策制定者努力使更环保的模式成为汽车更可行的替代品。 后者将造福于地球;前者将造福于当地公民。预计社会上最没有能力拥有和驾驶汽车的人将特别受益。 这项工作将有助于科学教育，因为它将支持两篇博士论文，其研究结果将被纳入加州大学的课程。伯克利，也许在其他地方。
