Reliability is a fundamental factor in the operation of bus transportation systems for the reason that it signifies a straight indicator of the quality of service and operator’s costs. Todays, the application of GPS technology in bus systems provides big data availability, though it brings the difficulties of data preprocessing in a methodical approach. In this study, the principal component an...

An integrated urban transportation system usually consists of multiple transport modes that have complementary characteristics of capacities, speeds, and costs, facilitating smooth passenger transfers according to planned schedules. However, such an integration is not designed to operate under disruptive events, e.g., a signal failure at a subway station or a breakdown of a bus, which have ripp...

This paper proposes a new formulation for the school bus scheduling problem (SBSP) which optimizes starting times for schools and associated bus routes to minimize transportation cost. Specifically, the problem determines the minimum number of buses required to complete all bus routes under the constraint that routes for the same school must arrive within a set time window before that school st...

Until the end of the 20th century it was common that cities organized, financed and managed their own public transportation systems. More recently—in Italy mainly during the last decade—many countries liberalized the service provision of public transportation. Indeed, while o↵ering local public transportation is a political and financial duty of governments, the service provision is outsourced ...

This paper proposes the solution for improving the services provided by the transport management by using GPS and GSM modem integration. The system mainly consists of three modules. (1) Bus station module (2) Bus module (3) Base station module. The modules are connected to PC and GSM modem. The initial information containing the bus number and license plate from bus station module is sent to bu...

Most bus transit systems only offer direct service between a small fraction of the origin/destination pairs that they serve. As a consequence, many travelers must transfer between bus lines to complete their journey. In this paper schedule control policies are created to minimize transfer time under stochastic conditions. We determine how long a bus should be held at a transfer stop in anticipa...

background the most accidents can be directly attributed to human factors. hence, more traffic crashes result from driver malfunctioning which from among them, the driver behavior is a proximal factor in the road traffic injuries causation chain. objectives this study aims to investigate relationship between aberrant driving behaviors questionnaire (dbq factors) and self-report crashes involvem...

Fine particle (PM(2.5)) emissions from traffic have been associated with premature mortality. The current work compares PM(2.5)-induced mortality in alternative public bus transportation strategies as being considered by the Helsinki Metropolitan Area Council, Finland. The current bus fleet and transportation volume is compared to four alternative hypothetical bus fleet strategies for the year ...

The theory of logistic transportation systems deals with models of phenomena connected with movement of goods and persons. The developed model of the transportation system is expected to simulate a real system, but also should help us to solve given transportation tasks. In order to describe transportation system (rail, bus or air), as a routine a connection graphwould be used. Vertices of the ...
