BACKGROUND Professional drivers have been found to be at high risk for developing low back pain. However, the exact reasons are poorly understood. OBJECTIVES To assess the prevalence of LBP among Israeli professional urban bus drivers, and evaluate the association between LBP in drivers and work-related psychosocial and ergonomic risk factors. METHODS A total of 384 male full-time urban bus...

This paper proposes an approach to evaluate the impact of bus network changes on bus travel time. The approach relies on data obtained from buses equipped with GPS devices, which act as mobile traffic sensors. It involves three main steps: (1) analysis of the bus network to determine which road segments are frequently traversed by buses; (2) computation of bus travel time patterns by segment; (...

A driver behaviour analysis tool is presented. The proposal offers a novel contribution based on low-cost hardware and advanced software capabilities based on data fusion. The device takes advantage of the information provided by the in-vehicle sensors using Controller Area Network Bus (CAN-BUS), an Inertial Measurement Unit (IMU) and a GPS. By fusing this information, the system can infer the ...

Abstract: The structure of bus network is very significant for bus system. To evaluate the performance of the structure of bus network, indicators basing on graph theory and complex network theory are proposed. Three forms of matrices comprising linestation matrix, weighted adjacency matrix and adjacency matrix under space P are used to represent the bus network. The paper proposes a shift powe...

Bus lanes have gradually become an indispensable infrastructure for the development of urban public transportation networks. A bi-level programming model is used herein to compare total travel time social vehicles and buses before after bus lane set up judge whether layout plan scientific reasonable considering road network. The model’s effectiveness verified using areas Qingshan Lake in Nancha...

Robustness studies on integrated urban public transport networks have attracted growing attention in recent years due to the significant influence overall performance of system. In this paper, topological properties and robustness a bus–subway coupled network Beijing, composed both bus subway as well their interactions, are analyzed. Three new models depicting cascading failure processes propos...

The paper discusses the benefits of specific user’s oriented tools in urban planning processes, throughout the applications of an original system devised to define the localisation of urban services based on traffic distribution. Operative examples concern the Italian city of Pavia. The system ULISSE (Urban Location Interactive System for SErvices), created by the author, uses a static model of...

Social systems have recently attracted much attention, with attempts to understand social behavior with the aid of statistical mechanics applied to complex systems. Collective properties of such systems emerge from couplings between components, for example, individual persons, transportation nodes such as airports or subway stations, and administrative districts. Among various collective proper...

State estimation is used in power systems to estimate grid variables based on meter measurements. Unfortunately, power grids are vulnerable to cyber-attacks. Reducing cyber-attacks against state estimation is necessary to ensure power system safe and reliable operation. False data injection (FDI) is a type of cyber-attack that tampers with measurements. This paper proposes network reconfigurati...

This paper presents an agent-based approach to design a Transportation Regulation Support System (TRSS). Based on a multi-agent modeling of a urban transportation network, the objective of our approach is to integrate the functionalities of the existing information system with the functionalities of a decision support system. The TRSS monitors the network activity and adjusts itself to the envi...
