Traffic lights: putting a stop to unsafe patient transfers

Traffic lights: putting a stop to unsafe patient transfers.

Poor handover between doctors is a recognised cause of error in hospitals.[1] Watford General Hospital is a busy acute trust in southern England, where high admission rates necessitate timely patient transfers from the acute admissions unit (AAU) to the medical wards. We found that doctors were infrequently informed of patient transfers, and they rarely handed over patient care when a patient w...

A traffic lights approach to PD validation

As a consequence of the dependence experienced in loan portfolios, the standard binomial test which is based on the assumption of independence does not appear appropriate for validating probabilities of default (PDs). The model underlying the new rules for minimum capital requirements (Basle II) is taken as a point of departure for deriving two parametric test procedures that incorporate depend...

Self-organizing Traffic Lights

Steering traffic in cities is a very complex task, since improving efficiency involves the coordination of many actors. Traditional approaches attempt to optimize traffic lights for a particular density and configuration of traffic. The disadvantage of this lies in the fact that traffic densities and configurations change constantly. Traffic seems to be an adaptation problem rather than an opti...

Agent controlled traffic lights

Due to several reasons, changing conditions in the environment do not always lead to changes in the traffic control units. The hypothesis of this research is that it may be useful to make use of self evaluating and self organising intelligent (urban) traffic control systems. In this research we focus on the applicability of autonomous intelligent agents within urban traffic control (i.e. traffi...
