This paper analyzes the routing of agricultural freight from the fields to the elevators. A number of optimization models are built to analyze the effects of truck type restrictions in the truck mix on the overall system cost of delivering from fields to elevators. The models account for both the selection of truck type and load type for deliveries while respecting the load restrictions imposed...

We investigate the use of large-scale Automated Highway Systems, also called one-dimensional vehicle platoons, as a practical traffic mitigation solution. We review recent theoretical results related to vehicle platooning and discuss their implications on the scalability and safety of large-scale platoons. We also quantify the performance of different platoon control strategies through simulati...

population growth and urbanization increase the demand for developing new roads. heavy traffic of the east of tehran imposes high pressure on transportation. network of this city and old road of tehran-rudehen does not meet this need. therefore, constructing the new highway (tehran – pardis) in the east of tehran would be needed. but the new highway passes through protected area of jajrood an...

A Ithough the number of traffic accidents each year has been substantially reduced over the past decade, highway crashes continue to be a serious problem in the United States. In 1983 approximately 42,400 persons died in highway crashes, and 2 million suffered nonfatal injuries. The 217. reduction in annual highway fatalities and the 367. reduction in the highway fatality rate (fatalities/lOO m...

ITE JOURNAL / NOVEMBER 1999 HIGHWAY-RAILROAD GRADE crossings are a relatively unique and sometimes perilous intersection of two transportation modes. The cost of collisions at these intersections is high in both dollars and human lives. The amount and type of sight distance provided at highway-railroad grade crossings can have significant impacts on safety. The proper calculation of these sight...
