This study aims at identifying the differences of crash characteristics at basic segments between urban and intercity expressways. Crash rate (CR) model is firstly developed as a function of traffic density. The causes leading to different CR characteristics by expressway type are then examined considering the interaction of geometry, traffic flow and ambient conditions. Affecting mechanisms of...

We study a queueing system with Poisson arrivals on a bus line indexed by integers. The buses move at constant speed to the right and the time of service per customer getting on the bus is fixed. The customers arriving at station i wait for a bus if this latter is less than di stations before, where di is non-decreasing. We determine the asymptotic behavior of a single bus and when two buses ev...

The building density of Central Business District (CBD) is usually high. Land for a bus terminal is insufficient. In this situation, passengers in CBD have to walk far to take a bus, or take a long time to wait for a taxi. To solve this problem, this paper proposes an indirect approach: the design of a circle line of shuttle bus as a dynamic bus terminal in CBD. The shuttle bus can deliver peop...

We consider a high speed ATM bus, which can serve a small number of stations (~ 16). The bus is slotted and each slot is long enough to contain one ATM cell. Transmission on the bus is controlled by an arbitrator. Each station sends its status information to the arbitrator at regular intervals. Based on this information the arbitrator makes polling decisions. Due to transmission and processing ...

This paper assesses the perception of intercity rail passengers on station facilities at Joydebpur Railway Station in Bangladesh. The ordinal logistic regression (OLR) tool was applied to analyze 1000 responses 24 selected service and 5 demographic parameters. Critical consideration from perspective a developing country revealed six unique factors, namely Level crossing facility, Illegal establ...
