SAFETY OF NARROW LANES FOR TRAFFIC CONTROL AT A CONSTRUCTION SITE

This study has expanded upon the limited literature available on the use of narrow lanes in construction zones. Narrow lanes significantly affect accident rates and frequency as well as the kind and cause of accidents. The public's first exposure to the narrow 9 ft (2.7 m) wide lanes caused a statistically significant increase in the accident rate, from 1.68 accidents per million vehicle-miles before reconstruction to 2.63 accidents per million vehicle-miles in stage I. The narrow lanes apparently slowed traffic, resulting in fewer injury accidents even though there were more accidents during reconstruction. During stages II and III, when 10 and 11 ft (3.0 and 3.4 m) wide lanes were used, the accident rates were less than those in stage I or before reconstruction.
