For the purposes of post-disaster response and recovery we view the transportation system as a network whose nodes are transportation hubs and whose links correspond to various transportation modes. We focus on: (a) transport resources (e.g., first responders, supplies) from “depots” to nodes in need, and (b) evacuating people. Regarding (a), we present a Cooperative Receding Horizon (CRH) meth...

Understanding transportation mode from GPS (Global Positioning System) traces is an essential topic in the data mobility domain. In this paper, a framework is proposed to predict transportation modes. This framework follows a sequence of five steps: (i) data preparation, where GPS points are grouped in trajectory samples; (ii) point features generation; (iii) trajectory features extraction; (iv...

Transport and logistics today have evolved into a high-technology industry. Distribution is no longer about moving cargo over road or via air from A to B, but is a complex process based on intelligent systems for sorting, planning, routing, and consolidation that supports faster transportation, different transportation modes, fallback scenarios in case of failures, value added services such as ...

Traffic simulations need to include other modes of transportation besides car. This paper explains how this can be implemented in a large scale micro-simulation package. The most important element is to recognize that trips start and end on the walk network, and to explicitely model this mode.

1.1 Motivation Much research is currently being undertaken in transportation to create more realistic models of transportation networks that account for the spatial heterogeneity in those transportation networks (Mark and Sadek, 2004), and also the different modes of transport that may be used. Simply assuming that users will travel at the maximum speed limit for a particular class of road fail...

The recent US Commodity Flow Survey data suggest that transporting hazardous materials (HAZMAT) often involves multiple modes, especially for long-distance transportation. However, not much research has been conducted on HAZMAT location and routing on a multimodal transportation network. Most existing HAZMAT location and routing studies focus exclusively on single mode (either highways or railw...

We conduct a cross-sectional ecological analysis to examine environmental correlates of active commuting in 39,660 urban tracts using data from the 2010 Census, 2007-2011 American Community Survey, and other sources. The five-year average (2007-2011) prevalence is 3.05% for walking, 0.63% for biking, and 7.28% for public transportation to work, with higher prevalence for all modes in lower-inco...

This paper describes a multimodal transportation network (MTN) in which several unimodal networks (AGVs, hoists, lifts, suspended monorail systems, etc.) interact each other via common shared workstations as to provide a variety of demand-responsive workpiece transportation/handling services. The set of transport modes provides connection support for production flows treated as agents trying to...

Logistics are an important function of modern transport systems. Contemporary technological and spatial developments have improved the cost, efficiency and reliability of freight and passenger transport systems. At the same time, the negative environmental impacts of transportation have gained wide recognition and are at the core of issues of sustainability, especially in urban areas. Since the...

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...
