Welcome to my web site. I tried my best within my limited time to provide useful information and tools for UMD students, and data and software tools for transportation researchers and practitioners.

TMC Traffic Data-Archive Download Site. The data in this archive are continuously collected by the Traffic Management Center (TMC), a division of Mn/DOT, at a 30-second interval from over 3,500 loop detectors located around the Twin Cities Metro freeways, seven days a week and all year round. The collected data are then daily packaged into a single zip file and loaded into the UMD ftp server from TMC. The file format follows ... more

Mn/DOT R/WIS Data-Archive Download Site. The data in this archive are continuously collected by the Mn/DOT's Maintenance Office at a 10-minute interval from the Mn/DOT's statewide R/WIS, seven days a week and all year round. The collected data are then daily packaged into a single zip archive file and loaded to the UMD ftp server by UMD TDRL. The file format follows ... more

TDA Data Automation Project. The Minnesota Department of Transportation (Mn/DOT) has been responsible for collecting, analyzing, and publishing traffic count data from the various roadway systems throughout the state. The traffic reporting system mainly developed by the Traffic Forecasting and Analysis Section (TFAS) of Mn/DOT has been used in several federal programs, internal Mn/DOT applications, and many private sectors. The objective of this project is to continue the TFAS’ automation efforts by computerized integration of the current manual effort to import, filter, and analyze the TMC portion of traffic data contributed to the Mn/DOT’s Traffic Monitoring System. The resulting system will allow users to specify the conditions for acceptance tests required by TFAS for both continuous and short-duration count volume data. Once the filtering procedures and parameters are set by an operator, the raw data can be automatically processed by the system without human intervention. ... more

Unified Transporation File Format (UTSDF). UTSDF has been developed to provide a simple data format for archiving all types of data collected from today's transportation sensors. UTSDF is portable between any operating systems since it uses ASCII strings and standard zip compression. TDRL is presently in the process of converting all archived data into UTSDF and will provide data analysis and visualization tools.

District-1 Road/Weather Information Sytem (R/WIS) Site. This is an experimental web site for the NG-R/WIS project that is maintained at UMD as a part of Dr. Taek Kwon's research operation. The main goal is to develop visualization and analysis tools to help Mn/DOT District-1's road maintenance and general transportation operations. This site may update its contents without any notification except to Mn/DOT District-1 operators. To learn more about the Mn/DOT R/WIS, vist Mn/DOT Statewide R/WIS.

Visibility At Thompson Hill, I35. The I-35 Thompson Hill/Nopeming area is well known for reduced visibility problems. This link shows the numeric visibility of the area along with a realtime video image for visual verification purposes. Two types of cameras are presently in expremintation. If you see a black and white image, the computer is using only one target but also uses infrared light sources which are not visible from the image. If you see a color image, the computer is using six targets which are located at 20, 40, 100, 150, 200, and 300 meters. Click here to learn how to estimate visibility using the targets of the color image.
