Most of the decisions taken to improve road safety are based on accident data, which makes
it the back bone of any country's road safety system. Errors in this data will lead to …

Traffic events involving secondary incidents can be particularly problematic for the public
and for incident managers. This paper explores the associations of spatial characteristics …

Advances in geographic information system (GIS) software and exploratory spatial data
analysis (ESDA) techniques give transportation safety engineers tools to observe and …

The spatial nature of traffic crashes makes crash locations one of the most important and
informative attributes of crash databases. It is, however, very likely that crash locations …

When we detect the occurrence times and locations of traffic crashes in real life, we will face
the situation where multiple crashes occur along a long road during a specific time period …

Geocoding is the process of assigning latitude and longitude coordinates to data that
contain spatial information. Geocoded records of motor vehicle collisions are an invaluable …

Accurate occurrence time and location of a reported crash are critical to effective crash
analysis. Although there has been a proliferation of studies that attempt to correct the bias …

Errors in the accident data arise due to several individual and institutional shortcomings with
inaccurate or ambiguous locations being the most serious amongst them. To overcome this …

In this project we developed a new GPS-based Geographical Information Exchange
Framework (GIEF) to improve the correctness and accuracy of location data reported on …

The accessibility of various traffic data archived by advanced data systems in intelligent
transportation system (ITS) has been a critical issue to the efficient utilization of those …
