Generated Traffic : Implications for Transport Planning

  title={Generated Traffic : Implications for Transport Planning},
  author={Steven B. Colman},
ITE JOURNAL / APRIL 2001 TRANSPORTATION PLANNERS often compare traffic to a fluid, assuming that a certain volume of vehicles must flow through the road system like water through a network of pipes. But in many situations urban traffic is more comparable to a gas, which expands to fill available space. Road improvements that reduce users’ travel costs tend to attract traffic from other routes, times and modes, and encourage longer and more frequent vehicle trips. This is called generated…

Generated Traffic and Induced Travel Implications for Transport Planning
Traffic congestion tends to maintain equilibrium. Congestion reaches a point at which it constrains further growth in peak-period trips. If road capacity increases, the number of peak-period trips

This report summarizes basic principles for transportation planning. It describes conventional transport planning, which tends to focus on motor vehicle traffic conditions, and newer methods for more
Congestion Costing Critique: Critical Evaluation of the “Urban Mobility Report”
The Urban Mobility Report (UMR) is a widely-cited study that quantifies and monetizes (measures in monetary units) traffic congestion costs in U.S. metropolitan regions. This report critically
Critical Analysis of Conventional Transport Economic Evaluation 30 September 2013
Transportation economic evaluation refers to the process of quantifying and monetizing a transport policy or project’s benefits and costs. How it is performed can significantly influence transport
Aalborg Universitet Traffic forecasts ignoring induced demand
Although the phenomenon of induced traffic has been theorized for more than 60 years and is now widely accepted among transport researchers, the traffic-generating effects of road capacity expansion
Road capacity change and its impact on traffic in congested networks: evidence and implications
This article reviews explanations of, and international empirical evidence for, ‘induced’ traffic as a result of increased road capacity and ‘suppressed’ traffic as a result of decreased road
The New Transportation Planning Paradigm
This article examines the roots of the paradigm shift taking place in transportation planning, one that is changing how transportation problems are defined and solved as well as how system


In 1994, a government committee report showed that building roads can generate traffic. Since then, there has been a lot of interest in whether the opposite is true - can reducing road space for cars
What is induced traffic?
The purpose of this first paper is to spell out, as clearly as possible, what is meant by “induced” traffic and to relate its various components to the full range of behavioural responses by travellers.
Travel demand forecasts and the evaluation of highway schemes under congested conditions
It has long been argued, particularly by those opposed to the level of resources committed to the highway sector, that travel demand forecasts which are used to justify investments carry with them a
DO N E W HIGHWAYS GENERATE TRAFFIC? Some people seem to think there's a universal Law of Traffic Congestion ruling that traffic expands to fill the space available to it. T h u s , they believe it's
Highway capacity and induced travel: issues, evidence and implications
This paper objectively addresses the induced travel issue by answering the following questions: First, if new highway capacity does indeed "induce" new travel, to what extent compared to other
Induced Traffic and Induced Demand
The model employs this definition to evaluate highway improvement projects using benefit-cost analysis, incorporating effects of short-run traffic volume on changes in the generalized price, as well as effects of long-run land use and other economic feedback.
Incorporating Feedback in Travel Forecasting
The Clean Air Act Amendments of 1990 (CAAA) introduced new requirements for how transportation modeling for air quality analysis must be performed in nonattainment areas. Because of the degree to
The illustrations demonstrate that benefit estimates may be exaggerated by using an inappropriate No Build base for comparison with the improvement alternative, by ignoring the impact of induced travel, or by using speeds output by travel models to represent average daily travel speeds.
