This course examines the policy, politics, planning, and engineering of transportation systems in urban areas, with a special focus on the Boston area. It covers the role of the federal, state, and local government and the MPO, public transit in the era of the automobile, analysis of current trends and pattern breaks; analytical tools for transportation planning, traffic engineering, and policy analysis; the contribution of transportation to air pollution, social costs, and climate change; land use and transportation interactions, and more. Transportation sustainability is a central theme throughout the course, as well as consideration of if and how it is possible to resolve the tension between the three E's (environment, economy, and equity). The goal of this course is to elicit discussion, stimulate independent thinking, and encourage students to understand and challenge the "conventional wisdom" of transportation planning.

This course discusses fundamental traffic flow characteristics and traffic flow variables. Their definitions are presented, and visualization/analysis techniques are discussed and empirical facts are presented. The empirical relation between the flow variables and the bottleneck capacity analysis are discussed. Shockwave analysis and a review of macroscopic traffic flow models are presented. Traffic flow stability issues are discussed as well as numerical solution approaches. The lectures also show how macroscopic models are derived from microscopic principles. This course provides an overview of human factors relevant for the behavior of drivers. The car-following model and other approaches to describe the lateral driving task will be discussed. The lectures also pertains to general gap acceptance modeling and lane changing. Microscopic models for pedestrian flow behavior are discussed and an in depth discussion of microscopic simulation models will be presented.

Life in the city relies on the smooth operation of urban logistics. Everything from retail to services, construction to waste collection rely on an efficient and reliable freight transport system. However, with the increasing pressures of urbanization, this has to be balanced with the environmental and social impacts caused by transport activity. This is the challenge of City Logistics, a field of study that has significant practical implications for the world and the cities we live in. It is not merely a question of what is involved, but what can be done about urban freight transport to improve it for the sake of economic efficiency, quality of life, and sustainability. From a systematic scientific foundation of the field, this course will take you on a journey to learn how city logistics is understood and practiced in cities around the world. Our instructors, members of a renowned global expert network, will teach you the basics of this highly complex social system. Using their experience in real-world projects, they will illustrate how the knowledge learnt in this course is applied across industry and the public sector. This course caters primarily to university students or professionals working in urban transport infrastructure planning or logistics management. Whether you are simply curious about the topic or you intend to develop a career in these fields, this course will give you the tools you need to understand the complexities of urban freight transport systems. The course emphasizes the theoretical foundation, the rigorous evaluation, and a multi-disciplinary approach to this complex area. Course participants will benefit from numerous case studies of best practice in selected cities around the world, in a variety of business settings. Our emphasis on the global perspective is particularly relevant, since an understanding of local culture and political climate is an important factor in the success of any city logistics intervention. The course will provide an avenue for students to learn from their peers about the challenges faced in their respective cities, and how to apply the principles learned to the challenges faced in their own cities.

Do you know how important GIS is to the transportation industry? The spatial applications to this field are so extensive that they represent an entire sub-discipline within the GIS community. In this course, we'll learn about the primary modes of transportation and explore some of the spatial applications developed to meet the unique needs of each. We'll also take a close look at some key organizations in the industry and learn firsthand from more than a dozen transportation professionals about the role GIS plays for them.

In this course, we will introduce you to the fundamentals of sensor fusion for automotive systems. Key concepts involve Bayesian statistics and how to recursively estimate parameters of interest using a range of different sensors. The course is designed for students who seek to gain a solid understanding of Bayesian statistics and how to use it to fuse information from different sensors. We emphasize object positioning problems, but the studied techniques are applicable much more generally. The course contains a series of videos, quizzes and hand-on assignments where you get to implement many of the key techniques and build your own sensor fusion toolbox. The course is self-contained, but we highly recommend that you also take the course ChM015x: Multi-target Tracking for Automotive Systems. Together, these courses give you an excellent foundation to tackle advanced problems related to perceiving the traffic situation around an autonomous vehicle using observations from a variety of different sensors, such as, radar, lidar and camera.
