Institute of Transportation Studies Friday Seminar, Dec 12

December 12, 2014 - 10:00pm
Despite growing interest in urban consumption amenities, little is known about their origin and importance. This paper estimates the consumption value of urban density by combining travel microdata with Google’s local business data. This dataset allows to integrate travel costs into a discrete choice model for restaurants. I find that in high density areas, consumers enjoy large benefits from visiting places that they prefer, and relatively smaller gains from shorter trip time. These results demonstrate the importance of non-tradable consumption in explaining the value of cities, and represent the first estimates of the gains from variety in the service sector.

Institute of Transportation Studies Friday Seminar, Nov 7

November 7, 2014 - 10:00pm
Transportation-related air pollution, GHG emissions and energy problems are a significant issue in the U.S., China, and across the world. The World Health Organization estimates that urban air pollution causes 200,000 deaths per year worldwide and that it will be responsible for 8 million premature deaths from 2000 to 2020. Sacrificing transportation needs for environmental quality is simply infeasible since transportation provides a vital wheel for economic development.

Institute of Transportation Studies Friday Seminar, Oct 31

October 31, 2014 - 10:00pm
Adaptive traffic signal control systems are an emerging technology for urban arterial operations. This presentation focuses on the current status of adaptive traffic signal control system applications in the U.S. An overview of adaptive signal system deployments is first presented. Some insights of the advantages and drawbacks will be given. The results from some field before-after studies will be discussed. One particular issue is related to how a comparison is made against the time-of-day coordination plans. Potential biases can result if the comparison is against non-optimal time-of-day coordination plans. Signal optimization software does not necessarily generate truly optimized signal timing plans. Errors often result during the timing implementation process due to various factors. The presentation will also include a demo of a Smartphone based application called SMRT (Signal Management and Re-timing Tool) for facilitating field signal timing diagnoses and implementations.

AC Transit Plan ACT Workshop, Oct 30

October 30, 2014 - 9:00pm
AC Transit will be conducting public workshops across the District in the month of October to collect feedback from the public about current service and recommendations for future investment. That input will be used to develop revised recommendations for discussion in Jan/Feb 2015. This meeting is being hosted by Real Estate's Physical & Environmental Planning Group to collect feedback from the campus community.

Precautionary or premature? The politics of indirect land use change (ILUC) policy, Oct 29

October 29, 2014 - 10:00pm
Energy and Resources Group Fall 2014 Colloquium Series (ER295)

Institute of Transportation Studies Friday Seminar, Oct 24

October 24, 2014 - 9:00pm
Forecasts will play an increasingly important role in the the next generation of autonomous and semi-autonomous systems. Applications include transportation, energy, manufacturing and healthcare systems. Predictions of systems dynamics, human behavior and environment conditions can improve safety and performance of the resulting system. However, constraint satisfaction, performance guarantees and real-time computation are challenged by the growing complexity of the engineered system, the human/machine interaction and the uncertainty of the environment where the system operates.
