The urban traffic conditions are often changeable and random. In this paper, the multi-agent
urban traffic control system based on information fusion is put forward according to the
characteristics of urban traffic. The system framework and agent structure are discussed. The
coordination algorithm used by the proposed urban traffic control system is based on genetic
reinforcement learning and Nash Equilibrium game theory. The system is capable of
responding to changing traffic conditions in real-time. It has the ability to coordinate and
optimize the system through system self-study and adaptability. The validity of the algorithm
is tested using simulation analysis.

North-south transit traffic through Switzerland has been increasing, and continues to do so
today. Growing traffic volumes and the increasing need for maintenance and repairs as the
roads and their infrastructure deteriorate with age; frequently give rise to traffic problems and
congestion, as a recent traffic study and analysis of road congestion clearly shows. And there
are no signs of a slow-down in these trends. Switzerland’s transport policy sets out to
overcome these problems through sustainable traffic development, and focuses on shifting
freight transport from road to rail. As a measure and basis for promoting the transfer of freight
transport from road to rail, Switzerland introduced a capacity- and distance-based heavy
goods vehicle fee in 2001 that applies to all trucks over 3.5 tonnes and throughout the
country’s entire road network. In addition an efficient traffic management and information
strategy on national level is needed to improve the actual situation, to improve road safety and
to reduce the negative aspects of road traffic and transportation. The analyse of the actual
traffic situation and planned solutions are listed in the following chapters of this report.

UD-type communication is a communication standard between center and roadside devices
for traffic control in Japan. It adopts DATEX/ASN that is contention method for the
application layer and UDP/IP for the lower layer. The main objective of UD type
communication is to put together the logical channels between center and roadside devices in
one physical communication line. The important characteristic of UD-type communication is
that it is suitable to the direct communication between the roadside devices. It has some
advantages compared to the case that the center collects and disseminates all kinds of
information. UTMS (Universal Traffic Management Society of Japan) society sets up the
working group to study the applications of the direct communication between roadside
devices and make the standard. This paper reports the outline of UD-type communication, the
application example and the communication standard.

Efficient enforcement is a crucial factor in designing future CityTolling systems. This paper
outlines a solution to meet the common set of requirements for enforcement in conjunction with
different charging technologies. It starts by looking at the enforcement modules for an interurban
tolling system based on satellite positioning and how these were brought to bear in an
urban environment. The trial results of this technology in the City of London are then detailed,
thus in a charging scheme that is based on license plates. This paper concludes by demonstrating
how this same enforcement technology is prepared to work within DSRC-based tolling systems.
