Common Flaws in Forecasting
Forecasting may not only provide inaccurate estimates, but it may also support flaws leading to incorrect interpretations. When forecasting is used to support investment decisions for infrastructure developments, these flaws can be far-reaching in consequences such as fewer returns than expected and longer amortization. The goal is obviously to be
The Prediction of Future Outcomes
Forecasting is contingent upon predictability, where a result is expected to be consistently observed, and uncertainty, which is the level of potential deviation from expected results. The prediction of a future outcome, such as the traffic level (e.g. port or airport terminal, transit ridership) logically experiences a decline in predictability
The Flying Car Concept, 1951
The flying car is one of the most enduring anticipations about future transportation (here depicted as a helicopter-like vehicle) and a pervasive theme in science fiction (e.g. Blade Runner, Back to the Future, etc.). It essentially represents the utmost in terms of personal mobility and freedom that can be conceptualized
Development of Operational Speed for Major Transport Modes, 1750-2020
Technological developments have two significant consequences on transportation modes. The first involves the emergence of new modes, and the second concerns improving their operational capabilities, such as speed. Operational speed represents a speed that can be maintained across a network and is limited by regulations such as speed limits. For
Evolution of Transport Technology since the 18th Century
Since the 18th century, mechanization allowed each transportation mode to experience an evolution in motive methods and vehicles. New engine technologies can be used across several modes with specific adaptations. The first and most meaningful innovation was the steam engine which improved the performance of the maritime and railway modes
2.4 – Information Technologies and Mobility
Author: Dr. Jean-Paul Rodrigue Transportation is a service generating a substantial amount of information, and the diffusion of information technologies has transformed the mobility of passengers and freight. 1. Information Technologies and the Material Economy Information and telecommunication technologies (ICT) diffusion resulted in several economic and social impacts. Historically, information
Migration of Chapter 2 (Transportation and the Spatial Structure) completed
Chapter 2, covering transportation and the spatial structure, has been migrated to the new web site (transportgeography.org). Chapter 2 – Transportation and Spatial Structure Several links are still missing, particularly those to chapters and sections that have not yet been migrated.

Co-location is one form of influence that transportation has on the location of economic activities. In this case, the transport terminal such as a port, an airport, a rail station, or an intermodal rail yard provides a multiplying effect within a co-location zone. This zone is an adjacent area within
