A Multi-Criteria Gis-Based Route Selection Tool For Hazardous Material Transport: Consideration Of Environmental Consequence, Traffic Congestions And Costs, Bahareh Inanloo

FIU Electronic Theses and Dissertations

Hazardous materials are substances that, if not regulated, can pose a threat to human populations and their environmental health, safety or property when transported in commerce. About 1.5 million tons of hazardous material shipments are transported by truck in the US annually, with a steady increase of approximately 5% per year.

The objective of this study was to develop a routing tool for hazardous material transport in order to facilitate reduced environmental impacts and less transportation difficulties, yet would also find paths that were still compelling for the shipping carriers as a matter of trucking cost. The study started with …

Analysis Of Historical Travel Time Data, Mei Chen, Xu Zhang, Eric R. Green

Kentucky Transportation Center Research Report

Travel speed is a critical piece of information for many applications. The Moving Ahead for Progress in the 21st Century Act (MAP-21) states that calculating travel speeds illuminates the performance of the nation’s highway system. New technologies make the collection of speed data more straightforward than ever. Private vendors collect and sell this data, and KTC purchased speed data for 2010-2013 from NAVTEQ (now HERE). The main objectives of the research were to:

• Evaluate private sector speed data and its use in generating travel time based performance measures
• Create a mechanism to integrate this speed data with networks maintained by …

Civil and Environmental Engineering Faculty Publications

Petaling Jaya is a Malaysian city in the Petaling district of Selangor, over the past few years it has witnessed a dramatic growth in terms of population size and geographical importance. This has led to constant congestions throughout the city. A significant reduction in the annual cost of road accidents, congestion, energy consumption and pollution in the city can be obtained by implementing a modal shift from private vehicles to public transport. Urban transportation problems are highlighted in this study as well the factors that influence the use of private and public transportation. A survey was carried out on users …
