As the desire for travel becomes even greater, both for business and leisure, so the demands on
the infrastructure will also increase. In many developed countries the transport infrastructure is
already well established with little scope for new construction. Therefore many network
operators are considering how they can work their assets harder and achieve greater throughput
of traffic, whilst ensuring the safety of their customers. This need for extracting additional
capacity, coupled with relieving existing levels of congestion and maintaining a safe network, has
led to the consideration of new and innovative traffic management schemes or operational
regimes. These include dedicating certain lanes to specific types of traffic at different times of the
day to give priority and encourage car sharing (more commonly known as High Occupancy
Vehicles lanes), slow moving vehicles (to keep them in their own lanes and allow other traffic to
pass) and for use as part-time lanes. As these new and invitation schemes become part of today’s
landscape we need to identify and understand the behavioural responses to proposed signalling of part-time lanes.

This paper introduces a probe car system developed and tested for Beijing City in China,
which is based on GPS data of buses running on roads and provides the traffic information to
users. In the traffic information center, the system matches the bus location data on the map of
Beijing, calculates the average running speed and travel time on road links, and distributes the
traffic information to the public via Internet. Based on it, users can search suitable routes for
traveling in the city.

Over recent years there has been a growing demand for the provision of journey time
information... This paper will consider some of the reasons for this and discusses the relative
merits and value to a central government organisation in developing a system for providing
this information. The paper will also discuss the processes being developed to enhance
journey time data derived from diverse sources with a view to using it as a reliable source of
event monitoring for otherwise unmonitored roads.

Walking is the most fundamental means of human transportation. Unlike travel by car, human
movement, either on foot or with the aid of a wheelchair, includes vertical movement, using
stairs or elevators, for example. Although there have been amazing developments in car and
outdoor navigation systems, such as EZ-Naviwalk, navigation inside buildings or between tall
buildings is less advanced. We therefore propose a new 3-D positioning system that is driven
primarily by dead reckoning with the support of RFID technology, which can provide realtime
indoor or outdoor position seamlessly. This enables point-to-point ubiquitous navigation
for humans even inside buildings or between tall buildings. In addition, this pedestrian navigation
system can take user’s preferences into account by changing the costs of the road network
link costs in various ways. Altitude differences along the route may be important. For
example, routes having stairs must be avoided by wheelchair-bound users. In addition, timedependent
routing must be considered for indoor navigation. A positioning track accumulation
system is also implemented so that tracks can be stored and their information reflected in
order to incorporate new roads or attributes in the future.

Adaptive Cruise Control (ACC) is a standard product for passenger cars that can be bought from many manufacturers. ACC works for speeds higher than 30 kph and only under restricted conditions. The first part of this paper describes our TrafficJam Assistant (TJA) that extends ACC  functionality to velocities from 0 to 30 kph including fully automaticstop and go using Laserscanner  data. Safe automatic start of the vehicle is possible even in complex situations,e.g. with pedestrians crossing the road. The second part describes the extension of the traffic jam assistant into an actual full-speed-range ACC system.
