Infoconnectivity: The value of certainty and uncertainty for interconnected transport networks

Human behavior regarding transport depends on travel time estimation and not on measured travel times. Travel time is dependent on human body energy consumption for diff erent activities, which has been studied by the author over the last 30 years. Uncertainty can enhance time perception up to a factor of 5 compared to measured time, dependent on the certainty or uncertainty of the information system. Quantitative analysis has shown that information improvements at interchanges of transport systems can have a value equal to or even greater than time saving produced by expensive, huge infrastructure projects. The paper will present empirical results from studies over the last 40 years and the theoretical background.
