In recent years, Vehicular Ad-hoc Networks (VANET) as an emerging technology have tried to reduce road damage and car accidents through intelligent traffic controlling. In these networks, the rapid movement of vehicles, topology dynamics, and the limitations of network resources engender critical challenges in the routing process. Therefore, providing a stable and reliable routing algorithm is ...
Objective: The rate of road traffic accidents in Iran per capita and for the number of vehicles is much higher than the average in the world. The present study was conducted to investigate road traffic accidents in Yazd province during 2011-2015.Methods: The present study is a descriptive-analytic study in which data were obtained from data collection forms related to deaths from driving ...
this paper addresses a production and outbound distribution scheduling problem in which a set of jobs have to be process on a single machine for delivery to customers or to other machines for further processing. we assume that there is a sufficient number of vehicles and the delivery costs is independent of batch size but it is dependent on each trip. in this paper, we present an artificial imm...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
A new model and solution for the energy minimizing vehicle routing problem with time windows (EVRPTW) and customers’ priority is presented in this paper. In this paper unlike prior attempts to minimize cost by minimizing overall traveling distance, the model also incorporates energy minimizing which meets the latest requirements of green logistics. This paper includes the vehicles load as an ad...
The main of multi-depot vehicle scheduling problem (MDVSP) is to schedule the timetabled trips using limited resources, optimally. The problem is very important in the management of the transportation systems. One of the most useful ways to better manage these systems is to consider the real conditions including depot balancing constraints. To normalize the number of vehicles departed from each...
Pedestrians are among the most vulnerable road users. Speed of vehicles is considered as one of the major causes of danger for pedestrians crossing the street. Therefore, it is of utmost importance to devise suitable solutions to reduce speed of vehicles. One of these solutions is installation of Pedestrian Refuge Islands (PRI) in very wide midblocks. With regard to fluctuations in pedestrian a...
The overall age-adjusted rate of motor vehicle traffic deaths in the United States decreased 25% from 14.6 deaths per 100,000 population in 2005 to 10.9 in 2015. During this period, the rate declined in each of the county groupings, with the largest decline of 26% in the large fringe metropolitan and micropolitan counties and the smallest decline of 20% in rural counties. For both years, the ra...
In the existing work, it is observed that the algorithms are language dependent i.e. characters and numbers should be in local language and if the language is changed, then the character identification algorithm will have to be changed each time the language changes. This kind of problem has been targeted in the proposed work by using the statistical features of the text and can be fine-tuned e...
