Meaning of search radius in Drive & Arrive / ArrivalBoard

Hi there,

Today I was asked for the following situation:
  • A customer has several boards in the same city.
  • He uses the driver app.
  • Depending on how he specifies the destination (cityname only versus postcode only) he gets different lists of potential arrival boards.

This is caused by the following business logic:

The geocoordinates of the two input patterns are located in the same village but there is a small difference. The search radius in the app is set to about 3000m which is not configureable. (image is manually created so the radius may differ).

[SearchRadius-DAVE-2.pptx].png
destination Yellow: one board (#1)
destination Blue: two boards (#1 and #2)
destination Orange: two boards (#2 and #3)
destination red: no hits at all


So by specifying the town center (blue example) the interface finds Board#1 and Board#2.
By specifying the postal code the result is : Board#2 and Board#3

Best regards
Bernd
