New technologies for intelligent transport systems constantly appear on the market, but until now it was unclear how these could best be implemented for public transport, especially for planning. Modelling Public Transport Passenger Flows in the Era of Intelligent Transport Systems is a textbook edited by Prof. Guido Gentile of the Sapienza University of Rome and Dr. Klaus Nökel, Vice President Product Management & Software Development at PTV Group, that sheds light on the issue for the first time. Under the framework of the TransITS COST Action Programme, researchers from 21 European countries investigated which ITS developments could be used to benefit public transport, and how. They examined how modern technologies can be included in transport models to provide decision-makers with reasons for investing in implementation. The results were brought together in an English-language textbook aimed at a broad audience that includes practitioners, decision-makers, researchers and students. www.ptvgroup.com.
