Leaders make decisions every day of their lives, but how they do it changes dramatically over the course of their careers. At lower levels, the job is to get widgets out the door; action is at a premium. At higher levels, the job involves decisions about which widgets to offer and how to develop them. To climb the corporate ladder and be effective in new roles, managers need to change the way t...

Purpose The purpose of this paper is to review literature relating to vehicle utilisation, transport optimisation and the implementation of 'green' transport management measures within the freight industry with a view to minimise the negative impact of road freight transport on the environment. Design/Methodology/Approach This report first reviews the key constraints on vehicle utilisation, bef...

Natural disasters can severely impact transportation networks. In the hours and days following a major flooding event, knowing the location and extent of the damage is crucial for incident managers for a number of reasons: it allows for emergency vehicle access to affected areas; it facilitates the efficient rerouting of traffic; it raises the quality and reduces the cost of repairs; and it all...

Recently, since the car is often used as the movement means, the traffic is increasing every year. ITS (Intelligent Transport Systems) which provides drivers with plural information for smooth and safety drive has been required. As one of them, several studies have been proposed for the road traffic surveillance in the image processing. T h e traditional methods have almost observed the traffic...

with rapid economic development in many countries, transportation has increasingly become an extremely important component in the national economy and daily life. So it is very essential to build an intelligent traffic control and monitoring system in order to resolve the traffic congestion of roads and reduce accidents. One major factor that affects the traffic flow is the management of the tr...

Traffic congestion is one of the most serious problems that impact urban transportation efficiency, especially in big cities. Identifying traffic congestion locations and occurring patterns is a prerequisite for urban transportation managers in order to take proper countermeasures for mitigating traffic congestion. In this study, the historical GPS sensing data of about 12,000 taxi floating car...

Existing linear scheduling methods for earthwork activities lack accurate scheduling locations in road construction projects. Project planners and construction managers largely depend on subjective decisions for the allocation of resources at correct locations. This has caused uncertainties in planning and scheduling, and consequently delays and cost overruns of projects. Accurate information o...

Pond-breeding amphibians are affected by site-specific factors and regional and landscape-scale patterns of land use. Recent anthropogenic landscape modifications (drainage, agriculture intensification, larger road networks, and increased traffic) affect species by reducing the suitable habitat area and fragmenting remaining populations. Using a robust concentric approach based on permutation t...

BACKGROUND Road traffic injuries, especially those involving motorcycles, are a particular concern in Iran. We aimed to identify the specific cognitive dissonances and consonances associated with risky riding among Iranian motorcyclists. METHODS This was a grounded theory qualitative study of male motorcyclists who were ≥ 18 and were living in one of the three cities of Tehran, Isfahan and Ah...

Frequentist statistics is not well adapted to handling uncertainties inherent in managing natural resources. A frequentist approach typically involves estimating unknown parameters of ecosystem relationships and testing their statistical significance. While such information is useful, natural resource managers have a greater need to know the most likely current state of an ecosystem and whether...
