Attachment C <br />Prioritizing pedestrian safety interventions and preparing a plan of action <br />Attachment B <br />statistical authority can be used. Gathering all the data proposed usually requires <br />examination of multiple data sources. <br />If there are no official road safety statistics, or if official statistics do not cover the <br />minimum points fully or with adequate reliability, additional data collection such <br />as a hospital-based study (see Box 3.1) or a road safety audit (see Box 3.2.) may be <br />considered. However, it is important to assess the costs of additional data collection <br />and the value added by the information obtained. <br />BOX 3.1: The Addis Ababa Hospital Injury Surveillance System <br />Ethiopia is an African country that has made signifi- <br />cant investment in improving its injury surveillance <br />capacity. Initial work on injury surveillance started <br />in 2000 with the support of WHO, followed by the <br />government's efforts to strengthen the Traffic Police <br />Department's road traffic injury data management <br />capacity and to expand data collection nationally. <br />The hospital injury surveillance system was <br />established in 2000. It was implemented in all six <br />government hospitals in the capital city, Addis Ababa. <br />At the start of the project, detailed data on all injury <br />cases were collected using a pre-defined data collec- <br />tion form. Data collection has since been integrated <br />into the national health information system, and <br />data on injury cases are collected and recorded as <br />part of routine health statistics. The hospital injury <br />surveillance system collects the following data for <br />road traffic injury cases: <br />• age and sex of injured people; <br />• where the injury happened; <br />• date and time of injury; <br />• type of road user(s) involved; <br />• types of vehicles colliding with pedestrians; <br />• pre-hospital care received; and <br />• injury severity. <br />Traffic police data system strengthening efforts <br />started in Addis Ababa in 2002. Previously the traffic <br />police documented information about crashes using <br />a paper data collection form. The information was <br />then transferred to a log book for manual tabulation <br />and reporting. The strengthening effort, supported by <br />WHO, revised data collection and entry procedures <br />46 <br />• site and location of collision; <br />• vehicles/road users involved; <br />• number of people injured or killed at the scene; <br />• demographic data of casualties (for example, <br />name, age, sex, occupation); <br />• known factors contributing to the crash; and <br />• whether pre-hospital care was provided. <br />Data from these systems have been used by the <br />national road safety council to identify high risk areas <br />and to inform a policy development process around <br />interventions for pedestrians and other road users, <br />as well as other risk factors such distracted driving <br />and access to care for victims of road traffic crashes. <br />Source: 2,3. <br />Page 192 <br />so that data are collected in the field using a pre- <br />designed form and later entered into a computer <br />database for further analysis. In later years the gov- <br />ernment expanded the system to six major regions in <br />the country. The traffic police data system captures <br />the following data for road traffic crashes: <br />
