Abstract

Set Covering problems find the optimal provision of service locations while guaranteeing an acceptable level of accessibility for every demand points in a given area. Other than reliance on static,exogenously-imposed accessibility measures, these problems either exclude substantive infrastructure-vehicle interactions or only include fragmented infrastructure-vehicle interactions related to the routing considerations of households seeking refueling service as a requirement of performing routine, daily activities. Here, we address this problem by coupling a Location-Routing Problem (LRP) that uses the set covering model as a location strategy to the Household Activity Pattern Problem (HAPP) as the mixed integer scheduling and routing model that optimizes households’ participation in out-of-home activities. The problem addressed includes multiple decision makers: the public/private sector as the service provider, and the collection of individual households that make their own routing decisions to perform a given set of “out-of-home activities” together with a visit to one of the service locations. A solution method that does not necessarily require the full information of the coverage matrix is developed to reduce the number of HAPPs that needs to be solved. The performance of the algorithm, as well as comparison of the results to the set covering model, is presented. Although the application is focused on identifying the optimal locations of Hydrogen Fuel Cell Vehicle (HFCV) refueling stations, this proposed formulation can be used as a facility location strategy for any service activity that is generally toured with other activities.

Abstract

After the 2017 TuSimple Lane Detection Challenge, its evaluation based on accuracy and F1 score has become the de facto standard to measure the performance of lane detection methods. In this work, we conduct the first large-scale empirical study to evaluate the robustness of state-of-the-art lane detection methods under physical-world adversarial attacks in autonomous driving. We evaluate 4 major types of lane detection approaches with the conventional evaluation and end-to-end evaluation in autonomous driving scenarios and then discuss the security proprieties of each lane detection model. We demonstrate that the conventional evaluation fails to reflect the robustness in end-to-end autonomous driving scenarios. Our results show that the most robust model on the conventional metrics is the least robust in the end-to-end evaluation. Although the competition dataset and its metrics have played a substantial role in developing performant lane detection methods along with the rapid development of deep neural networks, the conventional evaluation is becoming obsolete and the gap between the metrics and practicality is critical. We hope that our study will help the community make further progress in building a more comprehensive framework to evaluate lane detection models.

Abstract

This paper ls a discussion of an in-depth evaluation study of highway data development and analysis activities of the Washington State Department of Transportation. Statistically based procedures and recommendations that were developed to streamline the highway data collection program are described. Opportunities to reduce manpower and equipment costs, streamline work activities, Improve the quality of data collected, and provide accurate and timely data for the various users were Identified. Given the focus on highway data, a major effort was devoted to the department’s traffic-counting program. However, many data items and programs were considered, and the following items received particular attention: traffic volume counting, including estimation of annual average dally traffic at any location tbroughout the state highway system; associated seasonal, axle, and growth factors; vehicle classification; trqck weight; and the relationships between the statistical sampling requirements recommended for these items and those associated with the FHWA Highway Performance Monitoring System (HPMS) in the state. Employing statistical sampling methods that complement the HPMS sample offers a strong potential for significantly Improving the cost-effectiveness of a statewide highway data collection program.

A distributed approach to network-wide traffic control management

Abstract

This paper presents a distributed architecture for area-wide incident response and traffic control management, composed of two interacting, real-time decision-support systems that are able to perform cooperative reasoning and to resolve conflicts. The two units exchange partial and potentially incomplete results during the execution of their problem-solving tasks and exploit inter-agent constraints to resolve inconsistencies that are due to the limitations of their information, in order to integrate local solutions into global, network-wide control plans. Reflecting the complexity of the interaction between the various agencies engaged in the management and control of urban networks, this approach takes into account the desire of each individual agency to preserve its autonomy and maintain the control of the facilities under its jurisdiction, but at the same time tries to exploit their willingness to cooperate and unify their problem-solving capabilities towards a conflict-free, integrated response to operational problems.
