Narrative:

Airport vehicle was conducting an airport inspection, under the preface of a 'pavement check.' north flow contributed because runway ends are co-located and conveniently used as traffic dictates. Poor communication between myself and airport vehicle is another contributing factor. I was not aware that he was proceeding back on the runway. It was discovered after the fact by a phone call to the operator of the airport vehicle. No corrective action was taken due to the non awareness of the error. The runway was clear when the aircraft was cleared for takeoff. Another contributing factor may have been the traffic situation at airport. C172 on runway 01 executing a touch-and-go, a baron 2 1/2 mi final runway 19 executing the ILS runway 19 approach, and other aircraft within the airspace. I have no human performance considerations because at the time of the issuance of a clearance, the runway was clear. The only action that could have taken place was that airport close the runway for extended operations. The vehicle was not visible at the time. The last position the vehicle was observed on taxiway B.

Narrative: ARPT VEHICLE WAS CONDUCTING AN ARPT INSPECTION, UNDER THE PREFACE OF A 'PAVEMENT CHK.' N FLOW CONTRIBUTED BECAUSE RWY ENDS ARE CO-LOCATED AND CONVENIENTLY USED AS TFC DICTATES. POOR COM BTWN MYSELF AND ARPT VEHICLE IS ANOTHER CONTRIBUTING FACTOR. I WAS NOT AWARE THAT HE WAS PROCEEDING BACK ON THE RWY. IT WAS DISCOVERED AFTER THE FACT BY A PHONE CALL TO THE OPERATOR OF THE ARPT VEHICLE. NO CORRECTIVE ACTION WAS TAKEN DUE TO THE NON AWARENESS OF THE ERROR.

C172 ON RWY 01 EXECUTING A TOUCH-AND-GO, A BARON 2 1/2 MI FINAL RWY 19 EXECUTING THE ILS RWY 19 APCH, AND OTHER ACFT WITHIN THE AIRSPACE. I HAVE NO HUMAN PERFORMANCE CONSIDERATIONS BECAUSE AT THE TIME OF THE ISSUANCE OF A CLRNC, THE RWY WAS CLR. THE ONLY ACTION THAT COULD HAVE TAKEN PLACE WAS THAT ARPT CLOSE THE RWY FOR EXTENDED OPS.
