Blocked segments

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.

Blocked segments

Post by sorin.slotea »

How to identify street segments that are blocked but used due to missing alternatives?
Thank you!

Hello Sorin,

I assume you need to gather the segments that are returned similar to this message taken from MAP&GUIDE Internet:

The term you are looking for is probably the violation. Violations occur if a route uses segments with constraints (e.g. TruckAttributes) and the routing parameters allow such conflicts.

You can use the following parameters to request so-called "violation" information as part of the routing output:
  • RoutingOption
    Explicit routing options
    Explicit routing options
  • Via snippet / profile:

    Code: Select all

    <?xml version="1.0" encoding="UTF-8"?>
    <Profile>
    	<Common coordinateFormat="OG_GEODECIMAL" language="en" majorVersion="1" minorVersion="0"/>
    	<Routing majorVersion="2" minorVersion="0">
    		<Course>
    			<Violations>
    				<SegmentBlockingViolations cost="50000" enabled="false"/>
    			</Violations>
    		</Course>
    	</Routing>
    </Profile>
Depending on the additional COST value the server will ignore some constraints if it is cheaper (virtually spoken) to drive through the conflict instead of performing a detour.
Sample route based on TruckAttributes violations. COST is set to 0. Routing takes regular track as without TruckAttributes but reports the conflicts.

The violations are reported in the RouteListSegment list (right). The column AdditionalRE just mentions that there are soem additional constraints - whether they are violated or not.

By the way: the cost value used in MAP&GUIDE Internet is 50000.

Cheers,
