This forum deals with any kind of routing computation whether it is simple A:B-routing, calculation of isochrones, simple matrix computation or nearest search.
in the recent weeks I received conspicious numbers of questions about toll... sounds like we should provide some details to get rid of misunderstandings:
Manual toll updates for xServers contain data of the latest and any prior set. So by performing Update #N you have access to the content of #(N-1), #(N-2),...,#(0). This info refers to xServers - MAP&GUIDE Desktop treats updates in a different way.
Ommiting a specific update #(N) is at your own risk: if the list of countries affected by this update doesn't contain the countries you are dealing with you might not face stress. But if you want to be safe we recommend that you apply each update right after the announcement. Otherwise it's like a blind flight. Please use our developer blog to be informed (news published by product management)
Most updates reflect new official law conditions - once new laws have been published (even on long term perspective) we generate the required tarifs in our data sets and provide the update (we did this with the belgian toll, too).
Besides manual toll updates provided at the developer zone's customer area (manual download) we also offer a plugin called CONTENT UPDATE SERVICE. After proper configuration this plugin retrieves toll updates (and live traffic info) from our so-called LAYER DELIVERY SERVER (LDS). Please check whether this plugin is a valid approach for you to ensure valid data.
OK, s much for the moment - I'm looking forward to your feedback and don't forget the upcoming toll webinar (German language) on march, 7th! There's still space on my invitation list!
and here is a comment of our product manager Carmen Nowack:
Important information on the Belgian toll. Like already mentioned in earlier news, the Belgian government introduced a complete new toll system. Usually, toll sections for dedicated way points are defined by the authorities. Each toll section does have a defined length. In case of exact toll cost calculation, those sections do have dedicated tariffs attributed. In case of average toll, the length of all routed toll sections would be multiplied with the costs per kilometre. This latter type of toll calculation can be a system defined by the country, but in some cases PTV does not have access to the complete tariff information (like for Italy in the past). Here, an average toll calculation is possible only. But for both types of toll calculations, it was not relevant on which map or map version this calculation was performed. The toll sections were fixed and as said therefore the length defined. The new Belgian toll deviates from the known methods. For the Belgian toll calculation, the routed street segments are added up and multiplied with the toll costs per kilometre. With this, the Belgian toll system reflects an average calculation. But this means also that the calculation depends on the map basis and how the street segments are digitized. So new segments or even missing roundabouts will lead to different results. Also the different way of digitizing the street segments at the map providers will influence the results. So PTV customers have to be aware that there will be unavoidable differences in the Belgian toll calculation between the OBUs used in the trucks, different map providers and different map versions.
