Speed patterns: fixed time of day in profile setting?

[michel_wsc]

Hello,
I want to work with speed patterns (i.e. historical traffic data) for routing and I want to use a fixed time of day to be used for route calculation (e.g. 8:00am).
Is there a way to save this time parameter in any property file or profile?

Best regards,
Uli

Hello Uli,

as far as I Know there are only two ways to specify the Date/Time context of a routing:

• Via RoutingOption.StartTime
• If RoutingOption.StartTime is empty the server's current date time is used.

I asked DEV to let me know whether there's a config value but I guess this isn't possible. I hope they correct me.

Best regards,
Bernd

Hello Uli,

though I am a bit sceptic about the following approach I let you know it exists:
My colleague from the core team mentioned that you could use the High Performance Routing approach. As you might know the required SEARCH GRAPH is calculated based on a tool named RoutingNetworkGenerator (xServer1) and the command line options are

• The profile name (incl. the names of potential feature layers such as PTV_TruckSpeedPatterns or PTV_SpeedPatterns)
• The reference time that should be used for the snapshot "experience"

So if you create a searchgraph file based on those values you might be able to refer to a time context.

Best regards,
Bernd

PS: xServer 2 provides a so-called SNAPSHOT mode which is also based on a reference time which has to be specified via API.
