A risk assessment model is constructed for the hazardous materials (hazmat) road transportation combining features of TransCAD traffic forecasts, and based on traffic planning network of spatial analysis and attribute process, the database for path planning of hazmat transportation was set up. Based on the TransCAD platform, this research analyzes the risk value of hazmat transportation in each...

Road safety has recently become a major concern in most modern societies. The identification of sites that are more dangerous than others (black spots) can help in better scheduling road safety policies. This paper proposes a methodology for ranking sites according to their level of hazard. The model is innovative in at least two respects. Firstly, it makes use of all relevant information per a...

In this paper, we propose toll-setting as an alternative policy tool to regulate the use of roads for dangerous goods shipments. We propose a mathematical formulation as well as a solution method for the hazardous materials tool problem. Based on a comparative analysis of proposed mathematical models, we show that toll policies can be more effective than the popular network design policies that...

Given a road network, a fundamental object of interest is the matrix of origin destination (OD) flows. Estimation of this matrix involves at least three sub-problems: (i) determining a suitable set of traffic analysis zones, (ii) the formulation of an optimisation problem to determine the OD matrix, and (iii) a means of evaluating a candidate estimate of the OD matrix. This paper describes a me...

We consider the problem of designating hazardous materials routes in and through a major population center. Initially, we restrict our attention to a minimally connected network (a tree) where we can predict accurately the flows on the network. We formulate the tree design problem as an integer programming problem with an objective of minimizing the total transport risk. Such design problems of...

The reduction of traffic crashes, as well their socio-economic consequences, has captivated the attention safety professionals and transportation agencies. most important activity for an effective road practice is to identify hazardous roadway areas based on a spatial pattern analysis crashes evaluation crash relations with neighboring other relevant factors. For decades, researchers have adopt...

The present paper reports an application of the Theory of Planned Behaviour (TPB) to the prediction of road-crossing intentions among adolescents. In addition, the sufficiency of the TPB was assessed by examining the additional predictive utility of moral norms, anticipated affect and self-identity. A sample of 1833 adolescents completed a questionnaire containing a scenario depicting a potenti...

The transportation of hazardous goods represents an economic activity whose consequences can have serious impact on the safety of transportation, the environment and human health. With the aim of reviewing the elements that affect the activity, this article presents a model for the transportation of hazardous goods of which, generally, there are two forms: the theoretical model for the transpor...

The transportation of hazardous materials is always accompanied by considerable risk that will impact public and environment security. As an efficient and reliable transportation organization, a multimodal service should participate in the transportation of hazardous materials. In this study, we focus on transporting hazardous materials through the multimodal service network and explore the haz...
