THE PERCEPTION OF MANOEUVRES OF MOVING VEHICLES. PROGRESS REPORT VI (FINAL REPORT) IMPLICATIONS OF PSYCHOPHYSICAL THRESHOLD MEASUREMENTS FOR THE NIGHT DRIVING SITUATION

AFTER A REVIEW OF THE PRINCIPAL RESULTS CONTAINED IN THE PREVIOUS REPORTS IN THIS SERIES, A GENERALIZED EQUATION IS DERIVED WHICH EXPRESSES THRESHOLD SPEED IN DEPTH FOR RELATIVE MOVEMENT AS A FUNCTION OF OBSERVATION DISTANCE AND OBSERVATION DURATION. ON THE BASIS OF THIS EQUATION CALCULATIONS ARE THEN MADE TO YIELD VALUES OF TWO IMPORTANT TEMPORAL PARAMETERS IN CAR-FOLLOWING, VIZ. "TIME UNTIL COLLISION" AND "FREE TIME". IT IS SHOWN THAT THERE ARE CIRCUMSTANCES IN WHICH THESE PARAMETERS TAKE VALUES WHICH ARE TOO SHORT FOR THE DRIVER TO ESCAPE A COLLISION AFTER HE HAS DETECTED THAT HE IS CLOSING ON A LEAD VEHICLE. SUGGESTIONS TO IMPROVE THE CAR-FOLLOWING SITUATION, IN HUMAN FACTORS TERMS, ARE PRESENTED. (A)
