Bridge failure, which is generally associated with serious economic and life losses, is defined as the incapacity of a constructed bridge or its components to perform as specified in the design and construction requirements. This paper presents an overview of current researches on the typical characteristics and causes of bridge failures based on 10 former investigations. Principal causes can be divided into internal causes and external causes or natural factors and human factors. Design error, construction mistakes, hydraulic, collision, and overload are the top 5 leading causes of bridge failures, resulting in more than70% of the bridge failures. Causes of bridge failures are closely related to regional economy,structural type, type of use, material type, and service age. The failure rate is very high for steel bridges, which is inseparable from excessive emphasis on structure strength but lack of consideration on structure stability and fatigue in early years. Researchers need to strengthen their research on the stability and fatigue of steel bridges, as well as inspection and maintenance. Extreme loads such as flood, collision, and overload contribute to a large number of bridge failures because of the lack of extreme loads data and design theory defects. It is critical for such bridges to have sufficient redundancy and capacity protection measures to reduce the probability of bridge failure due to extreme loads. Previous statistical methods and classification methods for the characteristics and causes of bridge failures lack unified standards, and a more scientific method needs to be established. A comprehensive electronic database on bridge damage and failures needs to be developed to establish damage models and conduct forensic studies to improve the design theory and specifications.

Paving self-luminous roads in cities has social and environmental benefits， including relieving the pressure on urban power generation and improving energy security. Drivers perceive pavement brightness as an important indicator of driving comfort. In the current state of knowledge， a thorough association between drivers’ perceptions of comfort and driving brightness has not yet been demonstrated. In four districts of Xi’an， China， 67 urban road sections were first selected for night-time pavement illuminance measurements under different light environments， and night-time pavement illuminance zoning was completed. Optical parameters (pavement reflectance ratio， retro reflectance coefficient， chromaticity coordinates， and luminous pavement brightness) of self-luminous pavements were measured in the laboratory. Further， a self-luminous simulation road model was established using the DIALux Evo software. The visual signals of the driver (pupil diameter and obstacle gaze time) were collected and evaluated for comfort according to a human-machine interactive visual event acquisition system. Based on the association between driving brightness and respondents’ reported subjective perceptions in the survey， the acceptable rate， comfort level， and brightness detectable level limits were created. The results indicated that a significant visual difference between the three self-luminous roads (high， medium-high， and low illuminations) and the target obstacle exists. The comfort level， acceptability， and brightness perception levels first decreased and then increased with an increase in brightness. The results of this study will help guide the comfort evaluation of luminous pavements and further promote functional research on self-luminous pavements.
