N2  - OBJECTIVE: With increasing traffic volume and urban development, more and more underground tunnels have been constructed to relief conflict between strained land and heavy traffic. However, as more and more long tunnels are constructed, tunnel traffic safety is becoming increasingly serious. Thus, it is necessary to acquire their implications and impacts. This study examined 4539 traffic accidents that have occurred in fourteen Shanghai river-crossing tunnels for the period 2011-2012 and analyze the correlation between potential factors and accident injury severity. <br><br>METHODS: An ordered logit model was developed to examine the correlation between potential factors and accident injury severity. <br><br>RESULTS: Results show that increased injury severity is associated with male drivers, drivers aged 65 years or older, accident time from midnight to dawn, weekends, wet road surface, goods vehicles, three or more vehicles, four or more lanes, middle speed limits (50-79 km/h), zone 3, extra-long tunnels(over 3000m), and maximum longitudinal gradient. <br><br>CONCLUSIONS: This article aims to provide useful and valuable information for engineers to develop interventions and countermeasures to improve tunnel safety in China.<p />  <p>Language: en</p>
