Attachm <br />Pedestrian safety: a road safety manual for decision-makers and practitioners <br />Attach <br />assessment should identify all data sources for the minimum data requirements and <br />make some assessment of their quality and reliability. Discrepancies in the number, <br />severity and patterns of pedestrian injuries across data sources should be explored <br />and, if possible, explained. <br />For further information on assessing data quality and data systems, please consult <br />Data systems: a road safety manual for decision-makers and practitioners, a companion <br />document in this series (z). <br />Minimum and complementary data for assessing the pedestrian <br />safety situation <br />Minimum data <br />Complementary data <br />How big is the problem? <br />• Number of crashes involving pedestrians. <br />Number of pedestrians killed in road traffic crashes. <br />Number of pedestrians injured in road traffic crashes. <br />Total number of road traffic fatalities and injuries, <br />preferably disaggregated by road user types. <br />What type of traffic conflicts lead to pedestrian crashes? <br />Involvement of cars, trucks, motorcycles, bicycles and <br />animal-drawn carts, etc. <br />• Vehicle manoeuvres (e.g. turning). <br />On what day of the week and at what time do pedestrian <br />collisions occur? <br />• Date and time of injuries. <br />How serious are the injuries? <br />• Severity of pedestrian injuries. <br />Which type of crashes lead to disability or life-threatening <br />outcomes? <br />• Outcome following collisions. <br />Who is involved in pedestrian collisions? <br />• Age and sex of those killed or injured as pedestrians. <br />Where do pedestrian crashes occur? <br />• Place of crash (specific location such as urban, rural <br />and type of road). <br />• Dangerous road locations. <br />How many people live in the area being <br />assessed? <br />• Total number of people in the <br />population under study (including <br />disaggregation by urban and non-urban, <br />by age and income). <br />How and why do people typically travel <br />around the area? <br />• Origins and destinations of trips. <br />• Transport modes used. <br />• Trip distances. <br />• Trip purposes. <br />What is the socioeconomic condition of <br />the area under assessment? <br />• Gross domestic product. <br />• Proportion of adults employed. <br />• Household income. <br />In many settings, the minimum data components listed in Table 3.1 can be found <br />in an official road traffic injury database that draws on police reports, and possibly <br />other data sources. Data sources other than police statistics generally do not include <br />information about crash location, crash type and vehicle involvement. Police data, on <br />the other hand, may not include reliable information regarding injury severity. The <br />questions posed in Table 3.1 should be answered using the best available data sources. <br />In countries where there are no official national statistics on a given complementary <br />data indicator, most recent estimates or projections by the national census or <br />C <br />B <br />Page 191 <br />
