Evaluating cyclist biometrics to develop urban transportation safety metrics.

The transportation safety paradigm for urban transportation - particularly safety for those walking and cycling - relies on counting crashes to parameterize safety. These objective measures of safety are spatially static and reflective of past events: they can be enriched by including the human response to risk at diverse infrastructure designs. This perceived risk has been well captured qualitatively in the transportation safety literature; in the following study, we seek to develop a quantitative methodology that captures perceived risk as a continuous measure of human biometrics.

Safety at the edge: a safety framework to identify edge conditions in the future transportation system with highly automated vehicles.

Automated driving systems (ADS) have the potential for improving safety but also pose the risk of extending the transportation system beyond its , beyond the operating conditions (operational design domain (ODD)) under which a given ADS or feature thereof is specifically designed to function. The ODD itself is a function of the known bounds and the unknown bounds of operation. The are those defined by vehicle designers; the arise based on a person operating the system outside the assumptions on which the vehicle was built.
