An early-warning indicator screening method is proposed in order to construct an early-warning system for vegetable prices. Through index contribution analysis and the application of a support vector regression algorithm, we compare the results of early warning before and after index optimization. Experimental results show that the proposed early-warning system was significantly improved after ...

Safety warning messages in owner’s manuals act as the visible and text based warning to users to avoid potential harm or injury. These warnings include those for DANGER, WARNING, and CAUTION. Current existing standards and general design principles give recommendations to safety warning message design, but they do not discuss the implications of adapting these recommendations to a broader range...

Nowadays modern cars integrate advanced driving assistance systems which range up to fully automated driving modes. Since fully automated driving modes have not come into everyday practice yet, operators are currently making use of assistance systems. While still being in control of the vehicle, alerts signal possible collision dangers when, for example, parking. The reason for the necessity of...

Forward roadway collision warning systems can reduce rear-end collisions, among other unsafe behaviors. Previous studies have shown that young drivers fail to scan adequately for latent hazards. The current driving simulator study investigates the effect of visual collision warning messages on drivers’ hazard anticipation ability, when presented either 2s, 3s or 4s in advance of a potential thr...

The delivery of user-tailored warning messages for heterogeneous user groups is a challenge rarely covered by hazard monitoring and Early Warning Systems (EWS) even though it is one of the four key elements of early warning systems identified by the United Nations International Strategy for Disaster Reduction (UN/ISDR). This article describes the concepts of generic information logistics develo...
