The Next Generation Simulation (NGSIM) program has provided us with amazing amount of traffic and driving behavior data from several locations such as Interstate 80 Freeway, US 101 Highway, and Lankershim Boulevard. The dataset comes with full recorded videos and processed traffic data every tenth of seconds.
While analyzing the data set, a research team at the University of Virginia’s Center for Transportation Studies discovered unrealistic driving behaviors such as two vehicles traveling almost overlapped positions, etc. Reviewing them manually by going over a huge text file was a truly timing consuming task.
The CTS research team decided to develop a visualization tool that can help identify such unrealistic data records.
The program was written in Java program and can be downloaded from the following link.
The zipped file contains the program and source code folder “ngsimAnalyzer” and five .bat files which one can click on to run. Each .bat file executes the program with a different one of the 5 NGSIM data sets. The NGSIM data sets are not included in the zip, so one has to put the 5 data sets in the same folder as the .bat files.
It is noted that the source code is provided as an open source and is protected by GNU General Public License.
A short video clip on the execution of the NGSIM analyzer applied to one of the datasets can be seen by clicking the following YouTube video.
If you have any questions regarding the NGSIM Analyzer program, please feel free to contact Dr. Byungkyu (Brian) Park at bpark[at]Virginia[dot]edu.
