A Transit-Based Evacuation Model for Metropolitan Areas

Journal of Public Transportation Article in Volume 17, Issue 3 (2014) by Xin Zhang and Gang-len Chang This paper develops a decision-support model for transit-based evacuation planning occurring in metropolitan areas. The model consists of two modules executed in a sequential manner: the first deals with determining pick-up locations from candidate locations based on the spatial distribution of the evacuees, and the second plans for the route and schedule for each transit vehicle based on vehicle availability and evacuee demand pattern. An overlapping clustering algorithm is first adopted in allocating the demands to several nearby clusters. Then, an optimization model is proposed to allocate available buses from the depots to transport the assembled evacuees between the pick-up locations and different safety destinations and public shelters. A numerical example based on the city of Baltimore … Read entire article »

Intelligent Taxi Dispatch System for Advance Reservations

Journal of Public Transportation Article in Volume 17, Issue 3 (2014) by Hao Wang, Ruey Long Cheu, and Der-Horng Lee This research proposes and tests a new taxi dispatch policy to improve the existing systems used by taxi companies in Singapore. The proposed method chains trips made by reservations at least 30 minutes before the customer pick-up times. In this paper, the taxi dispatching system, Singapore Taxi Advance Reservation (STAR), is defined. A novel trip-chaining strategy based on a customized algorithm of Pickup and Delivery Problem with Time Window (PDPTW) is proposed. The idea is to chain several taxi trips with demand time points that are spread out within a reasonable period of time and with each pick-up point in close proximity to the previous drop-off location. The strategy proposed has the potential … Read entire article »

HOT for Transit? Transit’s Experience of High-Occupancy Toll Lanes

Journal of Public Transportation Article in Volume 17, Issue 3 (2014) by Gregory L. Newmark  As more and more regions seek to implement high-occupancy toll or HOT lanes, more and more transit agencies seek knowledge to take advantage of this new infrastructure opportunity. Unfortunately, as is often the case with the rapid diffusion of a new technology, little information is available to guide policy. This research addresses the need for knowledge on the integration of transit with HOT lanes. It first identifies the salient elements of HOT lanes for transit agencies and then systematically compares these features across all 12 HOT lane facilities operating in the United States at the start of 2012. This paper combines a review of the limited literature on HOT lane/transit integration with detailed data collection from functioning projects. … Read entire article »

Evaluating the Effectiveness of Onboard Video Feedback Systems on Reducing Transit Collisions and Injuries

Journal of Public Transportation Article in Volume 17, Issue 3 (2014) by Michael Litschi and Peter Haas  In the mid-2000s, public transit agencies began testing onboard video feedback systems on buses, which capture short video clips when triggered by an unusual event such as hard braking, a sharp turn, or impact with an object. The objective of this study was to determine whether the systems have enhanced passenger safety by reducing the frequency and severity of collisions and injuries and to identify lessons learned from the implementation of such systems. The study concludes that the systems appear to have a positive impact on transit safety achieved through a reduction in collisions and injuries and the risky driving behaviors that contribute to them. The systems provide transit mangers with a wealth of information about their … Read entire article »

Analysis of Visitor Satisfaction with Public Transport in Munich

Journal of Public Transportation Article in Volume 17, Issue 3 (2014) by Diem-Trinh Le-Klähn, C. Michael Hall, and Regine Gerike  This study investigates the use of public transport by visitors in the city of Munich, Germany. It seeks to understand how visitors perceive public transport services and which factors influence their level of satisfaction. Data were collected from a survey in April and May 2012 with a random sample at selected tourist sites in Munich. Factor analysis resulted in four different service dimensions—traveling comfort, service quality, accessibility and additional features. Visitors were found to be generally satisfied with public transport services in Munich, and their perceptions are independent from most factors.
