• Abstract:
  Motorists generally follow the guidance provided by pavement markings, which are normally marked in ; coincidence with the longitudinal construction joints, when the markings are necessary. At some locations, ; however, there may be a difference between joints and markings, which may lead the motorists to follow ; joints instead of pavement markings. In the absence of detailed research on this topic, an effort was made ; in this study to evaluate the effects of unmatched longitudinal construction joints and pavement markings ; on the lateral positioning of vehicles. Sites with such characteristics were identified, and detailed data ; were collected at selected sites, using video camera techniques to capture movements of vehicles for ; longer durations. The video tapes were later reduced to extract necessary information. Distance from the ; pavement edge to the centerline of each vehicle, vehicle type, presence of vehicles in the adjacent lane, ; traffic volume, weather conditions, and vehicle movement were the main data parameters gathered while ; reducing the data. In addition, two surveys were also conducted to gather the opinions of practitioners. ; Photographs of the vehicles traveling at several other locations, on the sections of the road which had ; mismatched joints and pavement markings were also taken. The data was analyzed to check for the ; impact of the non coincident pavement markings and longitudinal construction joints. A more rigorous ; statistical analysis was carried out for observations at one of the locations. ; Based on the survey and analysis of field data, drivers’ lateral position seems to be affected by unmatched ; joints and pavement markings. It is advisable to make efforts to avoid such occurrences.
