Bus supervision deployment strategies for improved bus service reliability
Bus service reliability has always been a top concern for transit agencies and their customers. Unfortunately, there are several factors detrimental to reliable bus service. Outside influences such as weather, traffic, and road construction can wreak havoc on even the best laid plans. Internally, …

School bus crashworthiness
… travel to school and school related events by bus. Not necessarily all the journeys are short and safely driven. The potential for serious injuries is possible in the event of a crash. The severity of injury in an offset frontal impact is higher than the full frontal impact, because of the …

Neural bus networks
Bus schedules are unreliable, leaving passengers waiting and increasing commute times. This problem can be solved by modeling the traffic network, and delivering predicted arrival times to passengers. Research attempts to model traffic networks use historical, statistical and learning based models, …

Moving from conventional bus service towards bus rapid transit : establishing priorities
… when improving their current conventional bus service (CBS) towards a higher quality system such as Bus Rapid Transit (BRT). Four major tasks were conducted as follows. First a literatu re review was performed to study relevant prior research and BRT cases in operation in Pittsburgh, Los …

Modeling Diesel Bus Fuel Consumption and Dynamically Optimizing Bus Scheduling Efficiency
… very few models that estimate diesel and hybrid bus fuel consumption levels. Those that are available either require significant dynamometer data gathering to calibrate the model parameters and also produce a bang-bang control system (optimum control entails maximum throttle and braking input). …

Evaluating express bus service
Express or limited-stop bus services are a competitive effort by transit agencies to provide higher quality service to customers who make longer trips and place higher premiums on travel time, convenience and comfort. While express routes usually share the same roadway with local, more conventional …

A fault tolerant bus interface unit based on the nubus standardized bus architecture
… subsystems is provided by parallel communication busses. Satellite-based systems are susceptible to transient faults caused by cosmic radiation or alpha particles. In order for a system to be usable in such an environment, it must be designed to be upset tolerant. Functionality of the design must …

Virginia School Bus Driver Training: Does Training Program Adequacy Affect school Bus Accident Rates?
… Transportation, and Education all show school buses as having a significantly higher number of accidents per hundred million miles of travel than other forms of transportation. Such statistics are alarming and formal study of school bus accident factors has been limited. The purposes of this …

Factors influencing bus network design
Bus network design and frequency setting, the highest level subproblems in the bus planning process, have long-term impacts on bus network performance. Improving network performance not only improves the attractiveness of public transport and thus ridership, but cost-effectiveness as well because …

A microprocessor based bus relay
A microprocessor based bus protection scheme has been proposed for a single bus system which employs a new technique to overcome the problem of current transformer saturation. The protection scheme uses a combination of the percentage differential current principle and the phase comparison …

A Better Bus Map: How Good Transit Map Design Can Strengthen the MBTA’s Bus System
… Boston is poised to radically reimagine its bus system in the coming years. With an ongoing network redesign by the Massachusetts Bay Transportation Authority (MBTA) seeking to create a dense network of high frequency bus lines as well as growing political momentum for fare-free transit …

Applications of Connected Vehicle Technology to Address Issues of School Bus and School Bus Stop Safety
… crash data shows that the number of fatal school bus related crashes has remained nearly constant over the past ten years, despite an increase in available safety-improving technology. One of the main concerns related to school bus safety is the issue of illegally passing a stopped school bus. To …

Bus crew scheduling using mathematical programming
This thesis describes a bus crew scheduling system, IMPACS, which has been demonstrated to be successful for a wide variety of scheduling conditions, and is at present in regular use by three British bus companies including the largest, London Buses Ltd. The background to the bus crew scheduling …

Bus service design and schedule control
… times, which are magnified over time until buses bunch into pairs instead of being evenly spaced. This bus bunching phenomenon is well-known in the industry as an illustration of the instability of uncontrolled transit systems. It creates large temporal gaps in the service, which cause a …
