TLDR
A mapping between travel times and traffic flows is proposed and a framwork for using these data additionally to include environmental effects into intelligent traffic managemnt systems is proposed.Abstract:
Intelligent raffic mangement is widely acknowledged as a means to optimise the utilisation of existing infrastructure capacities. A major requirement intelligent traffic management is the collection of high quality data on traffic conditions in order to generate accurate real-time traffic information. The approach to be described here generates this information by a fleet of taxis equipped with GPS which act as Floating-Car-Data (FCD) provider for a number of metropolitan areas. The first part of this paper describes the methodology of setting up this data base. The information collected enables various applications such as real-time traffic monitoring, time-dynamic routing and fleet management. The second part of the paper proposes a framwork for using these data additionally to include environmental effects into intelligent traffic managemnt systems. To this end, a mapping between travel times and traffic flows is proposed. Some challenges related to the computation of emissions from velocity profiles are discussed. Equipped thes ingredients, an environmental friendly intelligent traffic management might be in reach.read more

Reliability of the current models of instantaneous pollutant emissions
TL;DR: The analysis was performed using the Modem model, developed from the measurement results obtained over a sample of 150 vehicles, representative of French, English and German fleets, over 14 representative driving cycles under urban conditions, showing the low reliability of the models used, which cannot be used to assess the impact of slight changes in the driving pattern.
