Safety

A new detector of breath alcohol for a driver has been developed. A mouthpiece is not
required for the detection because the driver’s breath is introduced to the detector by an
electric suction fan. The influence of fluctuations of the driver’s breath flow is significantly
reduced by the calibration of alcohol concentration using an oxygen level of the driver’s
breath that is measured simultaneously with alcohol. The detector is able to measure breath
alcohol concentration rapidly and easily, compared with current breath alcohol detectors that
use a mouthpiece. Good accuracy has been demonstrated in a test with subjects after alcohol
consumption.

The EU funded project eIMPACT included the evaluation of traffic effects of Intelligent
Vehicle Safety Systems (IVSS). Such effects directly turn into monetary effects in terms of
economic assessment. They can support or counter-weigh the safety benefits of such systems.
For deeper insight into the safety effects the traffic simulations carried out also indicated socalled
surrogate safety measures. They can supplement the dedicated safety evaluations. This
paper presents both, the traffic effects of selected IVSS and the safety parameters as they
result from micro simulations.

With the massive introduction of active safety systems in modern vehicles, it becomes more
and more difficult for the customer to understand the effectiveness of those systems.
Objective testing and evaluation methods are necessary to support this and are being
developed within the recently started European research project eVALUE. They will also
foster the development of new and advanced safety systems for future applications. This
paper gives an overview of the systems which will be regarded and a scientific approach for
the development of assessment procedures for those systems.

This paper introduces the work Transport for London has been doing in the field of Image
Processing or Video Analytics. TfL has been evaluating the technology and the market to
determine the suitability of such systems in a dense urban environment. Investigating topics
such as Digital video compatibility, “Smart Camera” deployment and developing a Test
Library to evaluate systems in a repeatable and robust manner.
A key part of the work undertaken has been a deployment of a small scale congestion
detection system to the London Traffic Control Centre (LTCC), extending their monitoring
capability.
