Project: Enhanced Coach and Bus Occupant Safety: ECBOS

Reference: S0123/VE

Last update: 23/10/2003 11:46:08

Objectives

The main objective of the project is to contribute to a reduction in the amount of injuries and fatalities of occupants involved in bus and coach accidents. Based on analyses of governmental databases a statistical overview regarding incidence within different types of bus accident will be derived. The relevant accident types can be determined and, through detailed accident reconstructions in combination with numerical and experimental test methods, the different injury mechanisms can be evaluated.

Based on this knowledge new test methods (numerical and experimental) will be developed. These test methods will form the basis for suggestions for new and extended written standards regarding bus safety. The validated numerical models can then be used as a basis for new developments. Different bus types, accident situations and occupant sizes will be considered.

Description

ECBOS is an EC funded 3-year project under the 5th Framework Programme aimed at improving occupant safety in coaches, city-buses and minibuses. Cranfield Impact Centre is one of 7 European partners undertaking the work, on behalf of the European Commission. DTLR is sponsoring CIC to carry out tasks within ECBOS, in return for periodic reports on the results of the project. DTLR will make a positive contribution to the proposals put forward by the project, via analysis and discussion of the data collected.

The new numerical and experimental methods developed by this project will promote enhanced safety for occupants within different types of buses involved in the most critical collision types. Suggestions for new standards will be developed, based on the various new test methods. A numerical model of an improved bus design will demonstrate the performance possibilities in various collision conditions.

Summary of results

  1. The project results identified:
    * the need to include the passenger mass in the vehicle roll-over test;
    * the extension of the rollover test to all bus, coach and minibus vehicles;
    * the establishment of the significance of frontal impact accidents as contributors to injury statistics and the need to devise appropriate test methods; and
    * the advancement of numerical models relevant to the simulation of impacts on the vehicle.
