This research aims to identify and analyze hazardous road locations on a main road in the area of
Muang District, Nakhon Rachasima Province, together with the application of accident clock in safety
planning and accident prevention for relevant stakeholders. Researchers have reviewed various
methods for the identification of hazardous locations, and then selected ‘Rate Quality Control’
technique to identify hazardous locations based on accident rates considered appropriate for the data.
In this research, a system approaching to identify hazardous locations on roadways in the pattern of
ASP.NET website was developed. The research applies Microsoft Visual Studio 2010 C# Express as a
tool to develop such system integrating with Microsoft SQL Server 2005 Express – an information
database pattern for data storage which is considerably more convenient, faster and easier to record, to
analyze and to store data. Thus, the locations of accident risks are visualized through the electronic
chart based on Google map to facilitate a quick and reliable analysis coinciding with data display of
accident clock for better understanding such locations in real conditions. As well, the outcomes would
help to identify factors affecting hazardous conditions in the focussed areas in order to reduce the
number of accidents and to continuously improve road safety.
