Abstract [en]

Buses are common sight in Seoul. According to the Seoul Open Data Plaza, a public data service of Seoul, about 7,482 city buses (including main, local, express, circular, and nightrider buses) were operated on 355 routes as of 2015. The number of passengers was estimated at 1.6 billion per year, with a daily average of 4.4 million passengers. Bus as a transport mode, accounts for about 27% of total modal share in Seoul, which makes it the second most used transport mode after the subway.  In 2015, there were an estimated 1,412 city bus accidents, in which 22 people were reported killed and 2,076 injured.

Many measures have been taken in terms of safety to minimize accidents, including installing special devices on buses to automatically collect drivers’ dangerous driving behavior data. In fact, unlike the subway in which cars move along fixed tracks and in a regular speed, dangerous driving occurs more frequently with buses due to the complex mixed traffic environment in which they operate, which involves a lot of attention and maneuvers. Such dangerous behaviors include sudden start, sudden stop, and sharp turn and most of them occur during lane changes. Also, as exclusive median bus lanes are operating on many main arterial roads in Seoul, entering or exiting these exclusive bus lanes may cause dangerous driving behavior which also have adverse effects on traffic flow.

Considering this facts, driver’s dangerous driving behaviors may not only be caused by the driver’s condition (such fatigue, psychology) itself, but also and more importantly, they represent a reaction to the driving environment conditions, including road facilities and their elements and characteristics such as geometry, road width and lanes, signal system and more. In other worlds, by analyzing dangerous driving behaviors of several drivers in a large scale as well as their relationship with their environment, the causes can be detected and locations for safety improvements can be predicted.  

Therefore, the purpose of this study is to evaluate the safety of road facilities such as geometry, road width and signal system by analyzing the frequent occurrence of dangerous driving behaviors on buses.
