Urban Freight Vehicle Flows: an Analysis of Freight Delivery Patterns through Floating Car Data

Freight car dispatching with generalized flows

In the freight car dispatching problem empty freight cars have to be assigned to known demands respecting a given time horizon and certain constraints. The goal is to minimize the resulting transportation costs. One of the constraints is that customers can specify the type of cars they want. It is possible, however, that cars of certain types can be substituted by other cars, either in a 1-to-1...

Data Flows in Urban Freight Transport Management System

Analysis of urban freight distribution measures

Urban Freight Distribution (UFD) represents a very important activity in terms of cities economy, but can also be a problem for the daily life of citizens, due to traffic, noise and environmental contamination. Therefore UFD activities must be managed cautiously, to avoid or minimise external negative effects. In this context, this research aims to evaluate existing UFD measures, ranking them f...

ESTIMATING FREIGHT FLOWS FOR METROPOLITAN AREA HIGHWAY NETWORKS USING SECONDARY DATA SOURCES For Presentation National Urban Freight Conference

We present ongoing work on developing an automated integration system for freight flow analysis and planning. To overcome the limitations of current estimation methods for commodity flows, we use reliable secondary sources, including small-area employment data, and derive estimates in a plausible way by means of a computational workflow. When available, we extract the data automatically from on...

Applying Vehicle Tracking and Palmtop Technology to Urban Freight Surveys

Following the success of the Victorian Activity & Travel Survey (VATS) of household travel, the Transport Research Centre (TRC) initiated a Freight Activity & Commercial Travel Survey (FACTS) to provide a much needed database of freight-related information for the Melbourne metropolitan area. The objective is to provide detailed, accurate and current data on freight travel and commercial activi...
