      <title>NJ Transit Northern Bus Garage Planning and Community Impact Evaluation</title>
      <link>https://trid.trb.org/View/2012465</link>
      <description><![CDATA[The primary goal of this proposal is to assist NJ TRANSIT’S Bus Service Planning department to create a complete roster of the 500 bus capacity Northern bus garage determining stats such as platform hours and non-revenue mileage totals for potential auditing purposes.

The intended outcome of the project includes several modules for bus dispatching, including data archiving, processing and visualization. These modules can directly be integrated with the existing HASTUS bus scheduling system from NJ Transit. The before and after analysis on key performance metrics will help provide insights on the impact of the new garage on the operational improvement of NJ TRANSIT bus operations in its service areas.]]></description>

      <title>Minimization of Fuel Consumption in City Bus Transportation: A Case Study for Izmir</title>
      <link>https://trid.trb.org/View/1254446</link>
      <description><![CDATA[In this study, the authors handle a real life optimization problem of a metropolitan city bus service. The problem's focus is the fuel consumption due to dead mileage, given the bus requirements of all route schedules. They obtain the optimal route bus-garage allocations that minimize the total distance covered in all pull-out and pull-in trips, and reach significant improvement levels with respect to the current situation. They consider the midday demand fluctuations on each route, so that some of the buses have to make extra pull-in and pull-out trips before parking at their night garages after ending their last service trips. Moreover, they develop a multicriteria model which takes into account the fuzzy levels of passenger satisfaction and parking safety combined with the previous minimization objective.]]></description>

      <title>Deadhead Trip Minimization in City Bus Transportation: A Real Life Application</title>
      <link>https://trid.trb.org/View/1251664</link>
      <description><![CDATA[The quality of public transportation services is one of the most important performance indicators of modern urban policies for both planning and implementation aspects. Therefore, along with the size of the city, the significance of appropriate cost evaluation and optimization of all related transportation activities increases as well. One of the most important cost factors for the public transport agencies is naturally the fuel consumption of the vehicles. In this study, the attention is focused on the metropolitan bus transport service. The specific aim is to minimize a significant portion of total fuel utilization that occurs due to the so called deadhead trip or dead mileage, which is defined as the idle distance covered by the vehicle between the garage and the route terminal stops without carrying any passengers. In this study, the results of four mathematical models for minimizing the total deadhead trip distance covered in city bus services of Izmir are presented. The models vary due to the inclusion of garage capacity restrictions or operator distinction for supporting both operational and strategical decisions. All models are applied to the recent bus schedule data, which consist of 293 routes, 1,424 buses and 10 garages, for obtaining the optimal route bus-garage allocations and garage capacities. The results of the Decentralized-Capacitated model, which is appropriate for quick implementation, promise a 7.8% reduction in total dead mileage. While on the other hand, if all garage capacities can be expanded and the bus service is maintained only by one operator as modelled in the Centralized-Uncapacitated case, even a 31.4% improvement is possible in the long term. The environmental gains as well as the financial benefits to be achieved when the solutions are actually implemented, justify the practical contribution of the study.]]></description>

      <title>Fleet Study of Brake Performance and Tire Pressure Sensors</title>
      <link>https://trid.trb.org/View/900372</link>
      <description><![CDATA[The purpose of this project was to conduct a field study of brake performance and tire pressure monitoring systems on commercial heavy-duty vehicles operating under real world conditions. The study evaluated six systems in total—three brake performance and three tire pressure monitoring systems from various suppliers participating in the project. Transit bus platforms were selected for this field test because of the severe urban, stop/start duty cycle under which transit buses operate—an environment that accelerates both brake and tire wear thus allowing the sensor systems to be heavily “exercised” over the study period. The test fleet included 12 test buses and 12 control buses. The buses were operated by the Washington Metropolitan Area Transit Authority in Washington, DC. The test site was the Four Mile Run maintenance garage located in Arlington, VA. During the course of the 1-year field test, the buses averaged 129 miles per day, and the test fleet traveled a total of approximately 762,580 miles. Four sources of data were used to evaluate the brake and tire monitoring systems: visual inspections, on-board self-diagnostic data, maintenance records, and technician interviews. Both the tire and brake monitoring systems were found to hold up to the rigors of an urban city environment, and to provide fleet managers with data that can be used to improve vehicle safety and maintenance practices. The information provided by such systems allowed managers to better plan and anticipate maintenance actions, and to initiate preventative maintenance in order to prevent potentially severe failures. Key challenges associated with introduction of the sensor systems included: implementation of proper training for maintenance staff; consistent and correct use of data obtained from the systems; and, disciplined inspections and tracking of the sensor systems themselves to ensure they did not add to the overall vehicle maintenance requirements.]]></description>

      <title>Impact of Maintenance Training on Florida's Transit Providers</title>
      <link>https://trid.trb.org/View/860427</link>
      <description><![CDATA[As the transit industry moves ahead into the 21st Century, four main issues are emerging in maintenance departments: a dramatic increase in new technologies in the vehicles themselves and the diagnostics and tools used to repair them; a number of new external regulations addressing environmental and access issues; an increase in focus on vehicle safety, and the need to attract new and retain existing talent in the industry. All of these issues point to a need for an increased focus on training in transit maintenance departments. In response to the growing need for maintenance training, the Florida Department of Transportation (FDOT) developed the Florida Maintenance Training Program (FMTP) in 1990. This innovative program, administered since its inception by the Center for Urban Transportation Research (CUTR), provides maintenance training to all of Florida's public transportation providers as a partial solution to maintenance training needs.]]></description>

      <title>Bus Depot Sets Standard for Urban Facility Design</title>
      <link>https://trid.trb.org/View/859192</link>
      <description><![CDATA[A new bus depot built by the Metropolitan Transportation Authority (MTA) New York City Transit (NYCT) in Maspeth, Queens, demonstrates a sustainable model of design/build construction. It was built in accordance with the 2004 New York State's Executive Order 111 "Green and Clean" State Buildings and Vehicles Guidelines. The project cost $217 million and is located on Grand Avenue. It is the most recent of three bus depot design/build projects in recent years. Features include a complicated multi-story structure capable of handling buses in second-story repair units. Support shots for major bus mechanical component repairs are located in the upper story of the 550,000-square-foot facility. It can handle 200 buses with room for another 29 in the repair bays. Special facilities include compressed natural gas fueling and defueling facilities and recycled rainwater for the bus washers. Energy saving construction includes natural lighting, insulation and special doors to keep temperatures steady as vehicles enter and leave. Multiple high-efficiency heat recovery units exceed effectiveness required by the code, and provisions have been made for a hydrogen fuel cell system and a photovoltaic solar system. The three-phase building commission plan is described, along with testing for all the integrated systems.]]></description>

      <title>Getting Mechanics Plugged in With Training</title>
      <link>https://trid.trb.org/View/859188</link>
      <description><![CDATA[This article describes efforts by transit agencies to upgrade their mechanic training programs to reflect the increased complexity of transit bus mechanical systems, the aging of the maintenance mechanic population, and the difficulty in finding funds to pay for system maintenance and training of maintenance personnel. While the federal government will pay for up to 80 percent of the capital cost of a piece of equipment, there is no federal program to pay for maintenance or training. The result has been a "learning gap," especially when it comes to electrical and electronic systems. Various agencies have put together partnerships with local colleges, unions and other parties to create training programs for current staff and to attract new employees to the transit maintenance field. Some observers predict that as much as 40 percent of the mechanic workforce will be retiring in the next five to 10 years, so that their younger successors need to be brought up to standards in the newest systems. Groups that have formed consortia for training initiatives are described, along with several agency programs that have developed in-house.]]></description>

      <title>Dispatching Buses in a Depot Using Block Patterns</title>
      <link>https://trid.trb.org/View/793393</link>
      <description><![CDATA[One problem that urban transit operations must consider is how to park buses arriving at the bus garage so that the right buses are available for the next day's trips in the right order.   If a bus of a certain type is needed at a given time, the buses that precede it in the lane must have departed already.  Maneuvers (i.e., rearrangements of buses within lanes) might be necessary to achieve this goal.   In this article, the authors adopt the point of view that any solution to the dispatching problem must be robust and the solution should minimize the number of parking lanes that must undergo maneuvers to reposition buses.  The authors formulate a model in which the depot lanes are filled according to one-block or two-block specific patterns.  The authors present two versions of this model, study their properties, and show that some real-life instances can be solved within reasonable times by a commercial mixed-integer program (MIP) solver.  They conclude that the solutions of the model are very robust, and can thus be used by transit authorities in real-life applications.]]></description>
