to Dec 08 were retrieved and photocopied from regional NHMP offices with permission ofthe officer in charge.Variables co<strong>de</strong>d from acci<strong>de</strong>nt registers inclu<strong>de</strong>d date, time, number and type of involvedvehicles, number of persons injured or who died in a reported crash, and whether crashoccurred during maintenance works. Variables co<strong>de</strong>d from crash reports inclu<strong>de</strong>d date, time,location, direction of lane (North-bound or South-bound), light, weather, horizontal andvertical road profile, road surface and shoul<strong>de</strong>r condition, ongoing maintenance, and crashcause [106].Type of crash was <strong>de</strong>fined as single vehicle, same direction, opposite direction,si<strong>de</strong>wise, pe<strong>de</strong>strian. When more than one type was i<strong>de</strong>ntified, crashes were co<strong>de</strong>d as crash ofmost vulnerable involved road user; the vulnerability <strong>de</strong>creasing or<strong>de</strong>r was: pe<strong>de</strong>strian;opposite direction; si<strong>de</strong>wise or at intersection; single vehicle; same direction [106]. Details onnumber, injury severity, and type of road user involved (pe<strong>de</strong>strian, ri<strong>de</strong>rs of two-wheelers, oroccupants of cars/jeeps, minibuses, buses, or trucks) were co<strong>de</strong>d separately. Severity was<strong>de</strong>fined as ‘severe’ when involved person was transported to hospital and ‘fatal’ wheninvolved road user died at crash scene or at hospital in first 24 hours of the event [85].AnalysisInformation on crashes from registers and reports were linked to make a single file based oncrash location (km) and crash date, available for all crashes. Crash, fatality, and severe injuryper 10 9 vehicle-km travelled for vehicle type and direction were computed using traffic countssurvey [83]. Proportion of crashes, fatalities, and injuries on HWZ were computed andcompared to other zones. Information on HWZ dates was only available for the Hy<strong>de</strong>rabad-Hala sub-section. Due to this limitation, crash, fatality and injury rates for work and normaltraffic zone were computed only for the 50-km-long sub-section. Crash, fatality, and severeinjury risks according to road directions, vehicle types and traffic conditions were comparedusing rate ratios with 95% confi<strong>de</strong>nce intervals, rate differences, and attributable riskproportions where appropriate [104, 107]. Associations of factors with HWZs crashes wereestimated from a multiple logistic regression mo<strong>de</strong>l, including all variables weakly associated(P
