It is much safer and more fuel-efficient to transport children to school in buses than in private vehicles. However, school buses still consume 8.2 million gallons of diesel fuel annually, and transportation costs can be a significant portion of school districts’ budgets. Children in dieselpowered school buses may also be exposed to higher levels of particulates and other pollutants than childr...

This paper proposes a bimodal urban traffic control strategy based on a multi-agent model. We call bimodal traffic a traffic which takes into account private vehicles and public transport vehicles such as buses. The objective of this research is to improve global traffic and reduce the time spent by buses in traffic jams so that buses cope with their schedule. Reducing bus delays is done by stu...

This paper considers several diierent algorithms that reduce the required number of buses for multi-chip module design. An eecient polynomial time algorithm that calculates the minimum number of buses needed given a particular schedule is presented. We also present three algorithms that minimize the number of buses during scheduling. Experimental results are shown that illustrate the eeciency o...

The objective of this study is to determine the occupant/driver exposure in public transport buses running on biodiesel (B20) and ultra low sulfur diesel (ULSD) buses in the city of Toledo, Ohio. This paper also presents a protocol used for carrying out an experimental study involving continuous monitoring of real-time in-vehicle pollutant concentrations. In-vehicle concentrations of six air po...

A new packet switch architecture using two sets of time-division multiplexed buses is proposed. The horizontal buses collect packets from the input links, while the vertical buses distribute the packets to the output links. The two sets of buses are connected by a set of switching elements which coordinate the connections between the horizontal buses and the vertical buses so that each vertical...
