Safety is the first condition to the traveler. The traffic accident
would bring the large damage to traveler. This study is to explore the
effects of crash data in space. We use five properties to describe the
characteristic of crash, and two mode to show the region of crash .We
apply GIS software (AreView) to build a system in crash analysis. In this
system, we have space analysis, property query, index compute and to sift
specially crash from the data.
Using the crash data from Jungshan Chiu, Taipei in 2001, and make
the space data of crash in digital map that is 1:50000. By the way, we use
intersection and section to differentiate high danger region. Compute the
danger index in the region that the analyst want to discuss it.
In this GIS-Based Accident Analysis System we have five property
to describe the characteristic of crash:
1.occured time: about year, month, day, hour, minute.
2.damage level: crash class, dead, hurt, crash type, hurt level,
car damage.
3.road data: max speed, road type, road kind, special space.
4.person data: person type, sex, career, education.
5.crash reason: traffic facility error, person error, weather.
We use four index in this system: crash count, crash count per-km,
Etan, Serious Index. In this propose we hope the analyst can use this
system easily, and it will be less the crash damage to our traveler. | en_US |
