Transit Itinerary Calculation On The Web: Based On A Transit User Information System, Martin Trépanier, Robert Chapleau, Bruno Allard
Transit Itinerary Calculation On The Web: Based On A Transit User Information System, Martin Trépanier, Robert Chapleau, Bruno Allard
Journal of Public Transportation
Transit path calculation is not yet widely available on transit authority websites. This is because the calculation of complete transit itineraries requires the integration of underlying components such as Geographic Information Systems (GIS) and operational database and, unlike a simple road application, involves a complex transportation network. In this article, a hybrid algorithm based on heuristics and optimization is presented for the calculation of urban transit itineraries including information on pedestrian access and egress paths, route sequences, schedules, and stops. The use of the Transit User Information System (TUIS) to support the calculations is emphasized. The TUIS uses the Totally …

Innovatively Saving The Future Of Transportation: Small Aircraft Transportation System (Sats), Jocelyn Nickerson, Brent Bowen, Russell Smith, Scott Tarry, Massoum Moussavi

The aviation industry is a rapidly changing entity of the world’s economy. Millions of travelers consistently choose aviation as their mode of transportation because it is reliable, time-efficient, and safe. However, high demand has led to delays, cancellations, and gridlock. As the need for efficient travel options increases, passengers will look for other avenues of travel. Fortuitously, the National Aeronautics and Space Administration (NASA) and its partners are developing a unique and innovative alternative to this problem. The solution, known as the Small Aircraft Transportation System (SATS), will likely change the face of general aviation (GA) as it is known …
Applicability Of Bus Rapid Transit To Corridors With Intermediate Levels Of Transit Demand, Graham N. Carey
Applicability Of Bus Rapid Transit To Corridors With Intermediate Levels Of Transit Demand, Graham N. Carey
Journal of Public Transportation
Bus Rapid Transit (BRT) has the potential to bridge the gap between conventional rubber-tired transit operations and rail systems. Based on relatively low-cost, proven technology, BRT is gaining acceptance in many communities around the world that are endeavoring to provide high-quality transit service. While proposed applications of this new mode vary considerably, some conditions may be more appropriate than others. This article explores, from the point of view of the practitioner, some of the benefits and drawbacks of BRT.
Detection Range Setting Methodology For Signal Priority, Peter Koonce, John Ringert, Tom Urbanik, Willie Rotich, Bill Kloos
Detection Range Setting Methodology For Signal Priority, Peter Koonce, John Ringert, Tom Urbanik, Willie Rotich, Bill Kloos
Journal of Public Transportation
A significant amount of delay to transit vehicles in urban areas is caused by traffic signals. Implementation of signal priority has the potential to reduce control delay caused by traffic signals. The implementation of these systems requires engineering studies that address both transit and traffic signal operations. A comprehensive program requires coordination between the transit agency and the transportation department to address needs of both agencies and users. The City of Portland and the Tri-County Metropolitan Transportation District of Oregon (Tri-Met) have been working on a program that exhibits the elements of such an effort. This article details the efforts …
Ottawa And Brisbane: Comparing A Mature Busway System With Its State-Of-The-Art Progeny, Sean Rathwell, Stephen Schijns
Ottawa And Brisbane: Comparing A Mature Busway System With Its State-Of-The-Art Progeny, Sean Rathwell, Stephen Schijns
Journal of Public Transportation
Brisbane, Australia’s new South East Busway, which opened in 2000–2001, is one of the most technologically-advanced Bus Rapid Transit (BRT) systems in the world. It represents the “state-of-the-art” in busway design, infrastructure, and operations management. The South East Busway and various other Brisbane busway initiatives are modeled on Ottawa, Canada’s transitway system. Since commencement of operation in the early 1980s, Ottawa’s network of bus-only roadways and stations has transformed the community into one of the most transit-friendly centers in North America.
Defining The Gross Cost And Net Cost Options For New Delhi Public Transport, Aaron Windecker
Defining The Gross Cost And Net Cost Options For New Delhi Public Transport, Aaron Windecker
Journal of Public Transportation
Increasing the use of public bus transportation and decreasing the use of private modes is the remedy for New Delhi's congested streets and polluted air. To achieve this, the provisioning of bus services in New Delhi should be privatized to reduce the financial burden on the government and augment capacity. Regulation of the privatized svstem will be needed to improve safety; prevent private operators from concentrating only on denser routes; improve reliability, punctuality, and other standards of quality; rationalize fares; and improve network design. This article discusses each of these goals and assesses the applicability in the New Delhi context …
An Empirical Exploration Of Bus Travel Times And Dwell Times In A Highly Competitive Exclusive Busway, Daniel A. Rodriguez, Arturo Ardila
An Empirical Exploration Of Bus Travel Times And Dwell Times In A Highly Competitive Exclusive Busway, Daniel A. Rodriguez, Arturo Ardila
Journal of Public Transportation
Busway transit has reemerged as a cost-effective transportation alternative for providing urban mobility. This article examines the operational characteristics of an exclusive busway svstem with high passenger ridership and subject to the competitive forces of individual operators. Results of a running time model suggest that the increase in running time associated with an additional passenger movement is low but that the delay imposed by recurrent vehicle deceleration and acceleration related to frequent stops is high. Frequent vehicle stops reduce fuel efficiency, increase pollution, reduce travel time, and decrease productivity. Results of several specifications of dwell-time regression models indicate that established …
