Demo: Security of Camera-based Perception for Autonomous Driving under Adversarial Attack

Abstract

Robust perception is crucial for autonomous vehicle security. In this work, we design a practical adversarial patch attack against camera-based obstacle detection. We identify that the back of a box truck is an effective attack vector. We also improve attack robustness by considering a variety of input frames associated with the attack scenario. This demo includes videos that show our attack can cause endto-end consequences on a representative autonomous driving system in a simulator.

Evaluating Individual Transit Route Performance

Working Paper

UCI-ITS-WP-77-9

Abstract

Increasing emphasis is found on the objective evaluation of public transit performance. In the past, transit management has often attracted little attention; growing public interest in transportation issues and increasing costs in public transit have brought transit management increased visibility. With such visibility, clear evaluation procedures become necessary. Performance indicators may be used to evaluate the performance of individual transit routes in much the same manner in which they evaluate the performance of the entire transit system. The selection of appropriate performance indicators requires the clear definition of goals and objectives for each transit system. Once selected, there exist several different ways in which performance indicators may be implemented and their desired standards defined. This report suggests techniques for the development of route evaluation procedures and the range of goals which transit might be expected to facilitate. It then reviews the route evaluation procedures used by three transit properties in California and two properties in other states.

Effect of Social Vulnerability on Taxi Trip Times during Hurricane Sandy

Findings

Abstract

The increase in the availability of GPS-based movement data has enabled the exploration of mobility patterns in urban transportation networks. Understanding the relationship between social vulnerability and transportation flows from big data during natural disasters is crucial for utilities and policymakers for decision-making purposes, such as evacuation and restoration planning. In this study, we explore the geographic variation of changes in trip times of taxi trips in New York City (NYC) before and after Hurricane Sandy (2012) using GPS trajectory data in relation to the underlying socio-economic distribution of impacted populations using localized regression technique with GWR. The findings reveal how the spatial patterns of trip change times with respect to SVI, income levels and population density in NYC.

Systematic selection and siting of vehicle fueling infrastructure to synergistically meet future demands for alternative fuels

Journal of Energy Resources Technology

Abstract

In order to meet the increasing demand for low carbon and renewable transportation fuels, a methodology for systematically establishing build-out scenarios is desirable. In an effort to minimize initial investment costs associated with the development of fueling infrastructure, the analytical hierarchy process (AHP) has been developed and applied, as an illustration, to the case of hydrogen fueling infrastructure deployment in the State of California. In this study, five parameters are selected in order to rank hydrogen transportation fuel generation locations within the State. In order to utilize meaningful weighting factors within the AHP, expert inputs were gathered and employed in the exercising of the models suite of weighting parameters. The analysis uses statewide geographic information and identifies both key energy infrastructure expansion locations and critical criteria that make the largest impact in the location of selected sites.
