MapFormers allows you to geolocate your network in case it was created without any geographic reference. Result is WGS-84 geolocated network with appropriate georeference. This add-in will ask you for reference nodes. The more nodes you will reference the better results you will get. For each of them you need to point it exact location on the map. The more precisely you will specify node locations the better results you will get. If node references are collected press Next button. You can choose one of three available options. First one is appropriate for networks where scale for x axis and scale for y axis are equal. This case is unlikely in most cases. But it provides the most straightforward solution. Second option is appropriate for most cases. By means of linear regression it chooses the most coherent subset from referenced nodes and adjusts the network. You can specify the confidence factor for references (default 0.8). Third option is appropriate for adjusting acitve part of network. It doesn't adjust the scale, it only moves the network based on reference node, which number is to be specified with box on the right.

Python API for OMX
OCL tells you where to place counting locations in the transport model to get best results. Our tool employs acknowledged optimization technique to specify set of optimal counting locations catching as much flow and as many OD pairs as possible. OCL is the optimization procedure wrapped in intuitive, user friendly interface, which can quickly find optimal solution even for complex networks. User can define the budget (number of points that can be counted) and detectors which are already installed. It's also available to determine what kind of detectors we want to install: junction, link, directed link. Additional technical parameter is algorithm depth, being number of paths between origin and destination that are taken into calculation process. We propose various strategies of optimization. In our opinion, and due to our tests, the most useful is mixed maximization of both OD pairs coverage and flow coverage, however you can choose to maximize only flow, or only OD pairs. Running time depends on size of the network. On the average up-to-date PC it takes about 1 minute to download 300k paths (model for Kraków, Poland of ca. 350 zones), and then time of optimization itself depends on number of connectors and takes roughly 5s per detector. To see results visually, you can import prepared .gpa file. Additionally you can use our flow bundle generator, where you can clearly see which flows are covered with your detection. For detailed results and statistics you can see report including OD coverage, flow coverage, keys of detected elements, calculation time, etc. Screenshots

Description Plate Number survey (ANPR) 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 PTV Visum. Now all standard steps between APNR and OD. But not anymore: ANPR Support will support you with every step of ANPR data processing: Flexible data importer will create SQL database from your records. Powerful database engine will organize results Full Visum integration will import counting points' locations Filtering engine will show data you need (i.e. list of truck crossing two count locations during morning peak hour). Data processing machine will calculate OD matrices with several error detection procedures. You will be able to export travel time skim matrices, paths, OD matrices to Visum. You will see your results on histograms and charts. Summary take advantage of integrating ANPR 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. ANPR created by i2 runs as a script from Visum 12. It uses data from Visum network and ANPR data to provide not only advanced queries to ANPR database but also calculation of the characteristics based on Visum network and Count Locations.
