Berlin
As part of the HEAVEN project, near real-time
traffic data collected from a network of measurement points
and environmental data will be processed and integrated into
a Decision Support System (DSS). Berlin's HEAVEN system will
be based at the Traffic Management Centre, scheduled to open
in 2001. The centre will collect real-time traffic data from
158 measurement points in the city. A model of citywide
traffic will be constructed using the measured traffic data
and traffic modelling tools. The traffic management centre
can make predictions using the forecast models. Air
quality in Berlin is regularly monitored at 20 measurement
stations and noise data is collected in the 'BLUES' database.
The combination of data from the traffic
management centre and use of the existing models will allow
for the modelling of pollution levels in near real-time and,
eventually, at the street level for each major street in Berlin.
The DSS will help planning authorities and decision-makers
evaluate environmental situations at specific hot spots in
the city, which will aid the implementation
of transport demand management strategies and contribute
to the reduction of air and noise pollution in the city.
The HEAVEN project will also involve a preliminary
test of DSS in Beusselstrasse, a small area in
Berlin characterised by heavy truck traffic leading to very
high pollution levels. Noise emission limits are often exceeded
in this area and countermeasures must be taken in order to
comply with federal legislation.
