<title>A<sc>bstract</sc> </title> Good information is a key to good decision-making on large infrastructure projects. Decision-making is information-sensitive and empirical research shows that a lack of information may result in poor decision-making. The solution seems clear: more, better and timelier information. This...

<title>A<sc>bstract</sc> </title> Cost--benefit analysis (CBA) plays a major role in the <italic>ex ante</italic> evaluation of rail projects in many western countries. At first sight carrying out a CBA for rail projects seems straightforward, since cost estimates are almost always available, and the most dominant benefits are...

<title>A<sc>bstract</sc> </title> The preparation and implementation of large infrastructure projects present many practical problems. Recent literature has devoted much attention to budget overruns and overestimation of returns, partly in relation to the presence of misinformation. In the Netherlands, the...

The presence of missing values is an important issue for traffic data programs. Previous studies indicate that a large percentage of permanent traffic counts (PTCs) from highway agencies have missing hourly volumes. These missing values make data analysis and usage difficult. A literature review...

Route planning is usually carried out to achieve a single objective such as to minimize transport cost, distance traveled or travel time. This article explores an approach to multi-objective route planning using a genetic algorithm (GA) and geographical information system (GIS) approach. The...

This article discusses how the structure of the measurement system affects the short-term forecasts of travel time based on it. The effects of section length and location of different measurement stations were investigated. The study used empirical data. The research was carried out on a 28-km...

In this article, a discrete non-linear mathematical programming model with a variational inequality constraint is proposed to determine road tolls and time-varying congestion tolls for a freeway electronic toll collection system under a build-operate-transfer arrangement. An interdependent...

<title>A<sc>bstract</sc> </title> This article describes a search algorithm adapted to the Spanish Railway Network for generating as many traveling options as possible between two railway stations. This algorithm (Warshall's algorithm) uses connecting matrices to find all possible railway journeys. The Spanish Railway...

<title>A<sc>bstract</sc> </title> In comparison to personal travel, freight movements within large metropolitan areas are much less studied. Most conventional transportation models and planning analysis that disregarded freight flows have been criticized on the plausibility of their results and conclusions. To...
