WOULD RELAXING SPEED LIMITS AGGRAVATE SAFETY? A CASE STUDY OF HONG KONG

This study analyzed the impact of the recent speed limit relaxation on accident counts on 19 road sections in Hong Kong. By using the comparison group method, the study estimated the accident counts that would have occurred had treatment not been applied, and determined the corresponding accident changing factors. The results show that after the relaxation of speed limits the accident counts went up by about 20-30% after all possible factors were neutralized by the comparison group method. Judging from the statistical results, there is useful evidence to argue that the relaxation of speed limit does have an adverse impact on road safety.
