The software user interface
The Q-Traf software is controlled via 7 tabs.
- Tab 1 “log” is for information purposes only and shows the progress of the calculations.
The other 6 tabs group all the controls. They are :
- Tab 2 “Network files (wkt csv)” defines the wkt csv files of the network and zones.
- Tab 3 “Scenarios” defines the networks and matrices (names) to use. Each scenario consists of one network and one set of matrices. Several scenarios can be calculated simultaneously and compared (traffic difference and traffic conditions).
- Tab 4 “Vehicles” defines the vehicle types : Class (usually “Car”, “Truck”, “Bus”, “Pedestrian”), sub-classes or “authorization” to circulate on the links, and finally sub-sub-classes or matrices (each sub-sub-class corresponds to a trips / OD matrix). For example, Class “Car”, sub-classes “Car_1” and “Car_2” (some links can be open to “Car_1” and not “Car_2”, or vice versa), and finally sub-sub-classes “Car_1_1”, “Car_1_2”, etc., each corresponding to a single matrix. Matrices can thus be defined for zones, types of behavior …
- Tab 5 “Links Categories” defines the parameters for each link category (empty speed, hourly capacity, daily capacity, penalties, etc.).
- Tab 6 “Calculations” groups the assignment calculation parameters. There is no need to change them.
- The last tab 7 “Miscellaneous” groups parameters that the user does not need to use (which are currently under development, or have been abandoned).
Finally, on the right-hand side, the user can choose the language (currently only English or French), the speed unit, and save the newly modified parameters.
