## Abstract

Embodiments detect stops by an entity on a pre-planned trip that includes a plurality of stops. For each stop of the plurality of stops, embodiments determine a distance to a nearest stop and generate a geofence for each of the stops, each geofence having a radius having a size based on the distance. Embodiments detect the entity entering one of the geofences and, based on the detecting the entity entering one of the geofences, determine that the entity has stopped at a corresponding stop.

The method of claim 1, further comprising:
detecting the entity exiting one of the geofences;
based on the detecting the entity exiting one of the geofences, determining that the entity has exited the corresponding stop.

### Claim 4 (depends on 1)

The method of claim 1, wherein a first stop of the plurality of stops has a geofence radius of a first size and a second stop of the plurality of stops has a geofence radius of a second size that is different than the first size.

### Claim 5 (depends on 1)

The method of claim 1, wherein the radius (asr(S[i])) for each geofence corresponding to a stop (StopS[i]) comprises:
asr(S[i])=max(Rmin, min(max(Rd, csr), k*distanceToNearestStop(S[i])))
where:
0.1<=k<0.5;
0.01<Rmin<0.05;
0.25<=Rd<=1;
and csr comprises a configured stop detection radius of a Stop(S[i]).

### Claim 6 (depends on 1)

The method of claim 1, wherein none of the geofences overlap.

### Claim 7 (depends on 1)

The method of claim 1, wherein the entity comprises a vehicle and the pre-planned trip comprises a trip plan comprising, for the vehicle, a start location, an end location, and the plurality of stops.

### Claim 8

A non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more processors, cause the processors to detect stops by an entity on a pre-planned trip comprising a plurality of stops and a planned sequence of the stops, the detecting stops comprising:
for each stop of the plurality of stops, determining a distance to a nearest stop;
generating a corresponding geofence for each of the stops, each geofence comprising a radius, the generating automatically determining a size of the radius based on the distance to the corresponding nearest stop;
detecting the entity entering one of the geofences in response to receiving a geo-location message corresponding to the entity indicating a corresponding location and corresponding time for the entity;
based on the detecting the entity entering one of the geofences, determining that the entity has stopped at a corresponding stop.

### Claim 9 (depends on 8)

The computer-readable medium of claim 8, wherein the entity is associated with an Internet of Things (IoT) device that provides the geo-location, and the geo-location message is received via a gateway sensor that is configured to communicate with a plurality of IoT devices having different protocols and converting the different protocols to a standard protocol.
