In-Transit Cargo Crime Impacting The Retail Supply Chain, John Tabor
Journal of Transportation Management
Surveys of retail security directors show that almost half of those polled had been the victims of a supplychain disruption directly related to cargo theft. This is a significant increase from just five years ago. In order to fully understand the issue of cargo theft, retailers need to know why it exists, who is perpetrating it, how risk can be reduced, and ultimately how to react to a loss. This article explores a number of dimensions of the issue, and offers several suggestions for mitigating the risk and dealing with theft after it occurs.

How Much Do Users Value A Network Expansion? Evidence From The Public Transit System In Singapore, Eric Fesselmeyer, Haoming Liu
Research Collection College of Integrative Studies
We estimate the network effects of a public transit system by examining the impact of its expansion on housing prices. Our results show that a major expansion of Singapore's Mass Rapid Transit (MRT) system increased the price of apartments within 0.5 km of a pre-expansion station by 1.8% relative to apartments that were further away from a station. Evaluated at the mean housing price, the expansion increased the value of pre-connected apartments by at least S$455 million in aggregate, which is equivalent to 9% of the estimated S$5 billion cost of the expansion.

Deeptravel: A Neural Network Based Travel Time Estimation Model With Auxiliary Supervision, Hanyuan Zhang, Hao Wu, Weiwei Sun, Baihua Zheng
Research Collection School Of Computing and Information Systems
Estimating the travel time of a path is of great importance to smart urban mobility. Existing approaches are either based on estimating the time cost of each road segment or designed heuristically in a non-learning-based way. The former is not able to capture many cross-segment complex factors while the latter fails to utilize the existing abundant temporal labels of the data, i.e., the time stamp of each trajectory point. In this paper, we leverage on new development of deep neural networks and propose a novel auxiliary supervision model, namely DeepTravel, that can automatically and effectively extract different features, as well …

Evaluating And Enhancing Public Transit Systems For Operational Efficiency And Access Equity, Ran Wei, Aaron Golub, Liming Wang, Thomas Cova
TREC Final Reports
Assessing the performance of public transit services has long been an important yet challenging issue for transportation agencies and researchers. Transit service performance measurement reflects a very first step towards an efficient and proactive management, where public transit agencies are increasingly pressured to provide high-quality services in spite of constrained resources. However, the performance evaluation of transit services is complicated by an array of quantitative measures available to assess the goals and the diversity in the goals themselves, which usually include improving operational efficiency and providing equitable access. While much previous work has examined public transit services for achieving optimal …

Train Wrecks And Track Attacks: An Analysis Of Attempts By Terrorists And Other Extremists To Derail Trains Or Disrupt Rail Transportation, Brian Michael Jenkins, Bruce R. Butterworth
Mineta Transportation Institute
Attempts to sabotage rails and deliberately derail passenger trains have a long history in conventional and guerrilla warfare as well as during some particularly bitter labor disputes in the past. Since the 1970s, political fanatics have become a major adversary. Terrorists have sought to derail trains to achieve high-casualty events, while anarchists and issue oriented extremists have attacked rails to attract attention to their causes and impose economic damage. In this report, we examine the more than a thousand attempts to derail trains and to attack rail infrastructure to discern overall patterns and trends. We then look at four subsets …

Analysis Of Public Transportation Patterns In A Densely Populated City With Station-Based Shared Bikes, Di Wang, Evan Wu, Ah-Hwee Tan
Research Collection School Of Computing and Information Systems
Densely populated cities face great challenges of high transportation demand and limited physical space. Thus, in these cities, the public transportation system is heavily relied on. Conventional public transportation modes such as bus, taxi and subway have been globally deployed over the past century. In the last decade, a new type of public transportation mode, shared bike, emerged in many cities. These shared bikes are deployed by either government-regulated or profit-driven companies and are either station-based or station-less. Nonetheless, all of them are designed to better solve the last-mile problem in densely populated cities as complements to the conventional public …
