Plate number survey add-in for Visum


From raw input files to Visum OD and travel time matrices.



 i2 - Intelligent-infrastructure was working hard last months. We struggled to integrate powerful SQL engine with Visum. We struggled to process errors, to interpret results properly, to create user-friendly gui and we come back even more experienced. Below you can see latest development: From raw plate number results to OD matrix in Visum- that's what was definitely needed. Have a look!

1. Idea

Plate Number survey (APNR) is always a chance to improve your model. However it always comes along with data processing problems - thousands of records stored in numbers of files and all need to be processed to gather information. That's why we integrated data processing within VISUM. Now all standard steps between APNR and OD matrix in Visum are automated in user friendly graphical interface.


2. Functionalities

APNR Support will support you with every step of APNR data processing:
1. Flexible data importer will create SQL database from your records.
2. Powerful database engine will organize results
3. Full Visum integration will import counting points' locations
4. Filtering engine will show data you need (i.e. list of truck crossing two count locations during morning peak hour).
5. Data processing machine will calculate OD matrices with several error detection procedures.
6. You will be able to export travel time skim matrices, paths, OD matrices to Visum.
7. You will see your results on histograms and charts.

 3. Summary

- take advantage of integrating APNR data and VISUM network model in one flexible Add-In
- speed up your calculations with highly efficient database engine
 - work with user friendly GUI to simply see the data in tables, lists and plots or export ones to Visum and Excel.

APNR created by i2 runs as a script from Visum. It uses data from Visum network and APNR data to provide not only advanced queries to APNR database but also calculation of the characteristics based on Visum network and Count Locations.
