| dc.description.abstract | The numerical method is frequently adopted for traffic accident
analysis in the past. Because of temporal and spatial characteristics of
accident itself, the spatial relations of accidents can’t be clearly defined
and demonstrated by traditional numerical analysis method.
The initiative of this study is to reveal the spatial characteristics of
traffic accident. GIS is consisted of spatial functions such as query,
display, overlap, buffer zone and network analysis. According to that, the
temporal and spatial information about accidents can be realized and
prevent the recurrence of accidents.
The GIS software (ArcView) is adopted in this study. The historical
data is categorized by different administrative area, intersection, and
roadway attributes. The causes and levels of accident can be analyzed.
The results of the analysis can be the base of patrol and accident
There are four major properties to describe the traffic accident in the
1. Occurrence Time: Year, Month, Day, Hour and Minute.
2. Damage Level: Crash class, Crash Type, Dead or Hurt.
3. Roadway Attributes: Roadway Type.
4. Causes of Accident: Traffic facility errors, Personal errors, Weather,
The user-friendly interface is established and will be the strength for
the planning of patrol and prevention for further accidents. | en_US |
