The authors present an integrated GIS tool, Accessibility Analyst, for accessibility analysis in urban transportation planning, built as an extension to the desktop GIS software package, ArcView. Accessibility Analyst incorporates a number of accessibility measures, ranging from catchment profile analysis to cumulative-opportunity measures, gravity-type measures, and utility-based measures, con...

Executive Summary Collecting cyclist and pedestrian activity data can be challenging due to data gaps and unique characteristics of active transportation that set it apart from other modes. Technological advances continue to improve data collection for demograp...

The paper presents a planning process, a decision support system and an optimization model designed for the tactical planning of transportation by a logistics service provider (LSP) for customers from the automotive industry focusing on the primary target of sustainable transportation. Therefore a rolling to-be planning process has been designed which covers the planning activities for differen...

Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...

Road freight transportation is a major contributor to carbon dioxide equivalent emissions. Reducing these emissions in transportation route planning requires an understanding of vehicle emission models and their inclusion into the existing optimization methods. This paper provides a review of recent research on green road freight transportation.
