With R2 between 0.311 & 0.8531. Try to find more ambulance parking lot increased coverage of the area using the center of gravity method. Use data from District Office locations and population density per area in 9 districts in the northern part of Bangkok. Interested in this area because it is an area where the population has moved to live in the area has grown in recent years. The results obtained bycenter of gravity method will be compared with the results of other test methods to be tested in the next phase. Find increased ambulance coverage forresponse time up to international norms. Keywords - Ambulance Response Time, Emergency Medical Service (EMS), Emergency Patients, Coverage Area.
