Automatic Passenger Counting System For Trams
The system shown addresses the problem of automatic passenger counting (APC) in trams
with high utilization, uncoordinated boarding and lacking air suspension. Conventional APC
systems do not provide sufficient accuracy under these conditions. A concept for determining
the total weight of the vehicle using only data already acquired on the vehicle or available
from other sources has been worked out. The essence of the concept is that the actual weight
of the vehicle can be calculated from the driving dynamics, traction and energetic data of the
vehicle and the track geometry. The result can be used to calculate the weight of the
passengers exactly and to estimate their number at specific capacity utilization with sufficient
accuracy. The theoretical concept has been proven with measurements carried out on a
tramline in Budapest.

Future Challenges In Traffic Control
With the increase in urbanization, there is a continuous and growing need to manage traffic
signal controllers by more efficient and more cost effective means. Realizing that continual
expansion on existing infrastructure would be socially unacceptable and economically
unrealistic, Intelligent Transportation System (ITS) in terms of signal control systems has
proven to be an innovative and economical alternative means of making the best use of the
existing infrastructure. This paper elaborates the future challenges in traffic signal control
and management systems and describes how to face them in light of recent advancements in
ITS technologies and developments of new industry standards.

Standardized Device And Interfaces For Traffic Light Controllers
The German standardization initiatives OCIT and OTS aim at manufacturer mixable traffic
control systems. The specification of a controller-internal interface for traffic actuated control
methods contributes to this aim. This interface enables the unified interaction with different
traffic actuated control methods, so that the actual programming effort is no longer necessary
when integrating a control method into a certain type of controller. Traffic actuated control
methods may be easily exchanged with each other. To prove the operational reliability of the
interface, a prototypical traffic light controller has been developed. The novel system
architecture primarily is characterized by the separation of the safety and the traffic control
system parts. The developed prototype has been tested successfully in no-load operation at a
real intersection with the traffic actuated control methods TRELAN/TRENDS and VS-PLUS.

Integrated Traffic Signal Control And Management Platform And Its Application
As more and more cities adopt ITS for traffic management, ITS has play a more and more
important role in traffic control. However, till now, different ITS systems could not
communicate with each other. Although each of them has many unique characteristics, the
useful traffic data cannot be retrieved from different systems to allow a flexible collaboration
between each other. Thus, in this paper, a traffic signal control and management platform is
designed to integrate different ITS systems and provide unified traffic information fusion. A
typical application of the proposed platform in Beijing is also presented to show its
effectiveness.

Road User Protection Via Intelligent Camera Surveillance
Because of increasing traffic volume and complexity, road safety is now more than ever a hot topic on the government agenda. Traffic managers at all levels are organizing today debates with the following central topic: how can we better protect the road user? ‘More than 200.000 people killed each year in traffic’ or ‘close to 5,000 pedestrians killed in traffic in the U.S.A. every year’ is simply no longer acceptable.
One of the solutions to improve pedestrian safety is via Video Image Processing technology. This
video detection technology detects faster than any other detection technology. By analyzing the video images in real time, you immediately receive a clear image of potentially dangerous situations. Result: the danger of the incident is substantially reduced and secondary impacts are prevented. This Video Image Processing technology has proven to be very reliable for detecting pedestrians in tunnels. What about its performance in urban environments? Is this technology a valuable tool to help pedestrians crossing the street safe and sound? Yes.
Is video detection a cure-all? Just like any other ITS technology, this detection technology must be used correctly. Different applications require different cameras and different camera positions. One must not start implementing video detection technology without a complete understanding of the costs and benefits associated with these systems. If the correct guidelines and parameters are taken into account and implemented correctly, video detection has proven to be very reliable and can offer great solutions to the end user!
