xRoute1: Work with HPR and ExceptionPath

[hegedus.tibor]

Hi,

we discovered a strange behavior when we try to use a profile which has corresponding high performance data and the RouteRequest also contains exception paths.

In some cases, the module which tries to process the request is shutting down with exit code 134.
In other cases, we get the following error:

Error in building gp-nodes path from high-performance routing result

Could you explain this behavior and give us solution how to bypass this errors?

Br,
Tibor

Hi Tibor,

Is this deterministic?
I will forward this to dev.

Anyway: the combination of HPR and ExceptionPath shouldn't work: the HPR already contains the graph that is used for the "fibd route" process. Does not make sense to define further options at runtime.

I received some info from Frank S. (DEV). He confirms that a combination of HPR on the one hand does not work with

• API based Routing Options
• XML snippet
• Exception Path
• Live Traffic data

So whether the engine crashes or returns bu....it: you have been warned!

Attention: the statement above refers to xServer1!

In xServer2 it is at least possible to generate time dependent HPRs but even in that case you can't override options at runtime once the Graph is computed (and requested).

Best regards,
Bernd

Is it possible to create a HPR network to consider custom permanent road bans?

We have a list of road segments, which we never want to use during route calculation. Is there a way to define these segments in the profile xml (to generate the HPR from it)?

On Premise?

• Yes...
  Do you know how to define a CUSTOM FEATURE LAYER?
  Get back to me 1:1 for a specific intro...
• No... In the cloud you can neither produce custom HPR nor custom FL ;-(
