 In addition, if the reference point (i.e. the middle of the rear axle) or the mainLaneLocator (i.e. the middle of the agent front) are located within a LaneGeometryElement, s/t/yaw is calculated of each point, respectively.
 Further aggregation is done with respect to each road by calculating the minimum and maximum s for each road the agent intersects with. 
 For the current route of an agent, the following information is stored: s/t/yaw of the reference point and mainLaneLocator on the route (roads along a route are not allowed to intersect), distance from the lane boundary to the left and right for the road(s) along the route, and OpenDRIVE Ids of the lanes on the route that the agent touches. 
-The results also holds information wether both the reference point and the mainLaneLocator lay on the route.
+The results also holds information whether both the reference point and the mainLaneLocator lay on the route.
 In the currently implementation, these points must be located - otherwise the agent is despawened, as the agent cannot execute distance queries without a relation to its current route.
