A materials handling vehicle comprises a drive unit, steering unit, localization module, and navigation module which are configured to cooperate to direct the materials handling vehicle along a travel path in a warehouse. A path validation tool comprises environmental layout data of the warehouse, a proposed travel path within the warehouse, kinematics of the materials handling vehicle, a dynamic exterior boundary of the materials handling vehicle, and a dynamic clearance boundary of the materials handling vehicle. The dynamic clearance boundary is enlarged relative to at least a portion of the dynamic exterior boundary of the materials handling vehicle to define an enlarged boundary about at least a portion of the materials handling vehicle. The path validation tool is configured to: execute path validation logic to determine vehicle pose along the proposed travel path; determine whether the dynamic exterior boundary or the dynamic clearance boundary of the vehicle is likely to intersect obstacles represented in the environmental layout data, based on the determined vehicle pose and a degree of potential impingement at candidate positions along the proposed travel path, to respectively identify an obstacle collision error or a pinch point error; and modify the proposed travel path to avoid or mitigate against possible collisions and pinch points, wherein avoidance of collisions is prioritized over avoidance of pinch points.
