Article Abstract
The accidents caused by hazardous material during road transportation may result in catastrophic losses of lives and economics, as well as damages to the environment. Regarding the deficiencies in the information systems of hazmat transportation accidents, this study conducts a survey of 371 accidents with consequence Levels II to V involving road transportation in China from 2004-2018. The study proposes a comprehensive analysis framework for understanding the overall status associated with key factors of hazmat transportation in terms of characteristics, cause, and severity. By incorporating the adaptive data analysis techniques and tackling uncertainty, the preventative measures can be carried out for supporting safety management in hazmat transportation. Thus, this study firstly analyzed spatial-temporal trends to understand the major characteristics of hazmat transportation accidents. Secondly, it presents a quantitative description of the relation among the hazmat properties, accident characteristics, and the consequences of the accidents using the decision tree approach. Thirdly, an enhanced F-N curve-based analysis method that can describe the relationship between cumulative probability and number of deaths , was proposed under the power-law distribution and applied to several practical data sets for severity analysis. It can evaluate accident severity of hazmat material by road transportation while taking into account uncertainty in terms of data sources. Through the introduction of the as low as reasonably practicable (ALARP) principle for determining acceptable and tolerable levels, it is indicated that the F-N curves are above the tolerable line for most hazmat accident scenarios. The findings can provide an empirically supported theoretical basis for the decision-makers to take action to reduce accident frequencies and risks for effective hazmat transportation management.

Article Synopsis
- The study investigates how first responders and professional drivers view wearable technology for health monitoring during hazardous materials (HAZMAT) events, revealing significant differences in their perceptions and experiences.* -
- Professional drivers reported a higher likelihood of using wearable tech and being exposed to HAZMAT situations, and they were more open to having their health data monitored by others.* -
- While occupation influenced perceptions, individual characteristics like previous experience with wearable devices and willingness to share health data played a more crucial role in shaping attitudes toward health monitoring.*

Article Synopsis
- * A new model for Forward Collision Warning (FCW) has been developed that tailors alerts to drivers based on their individual driving styles and risk levels, optimizing when warnings should be issued during hazardous situations.
- * Research indicates that while all drivers receive similar warnings under high-risk conditions, there are distinct variations in optimal warning timing for different driver types in mid and low-risk scenarios, helping to improve both safety and driver confidence in ADAS technology.
