Abstract
Globally, approximately 3500 individuals are killed due to a road traffic injury each day, equating to nearly 1.3 million deaths each year and more than a million children are either killed by, or sustain serious injury, from road traffic incidents. School zones are locations where there may be high concentrations of children at certain hours of the day, thereby increasing their exposure to road and pedestrian injuries. The International Road Assessment Programme (iRAP), an NGO established in 2006, developed the Star Ratings measurement system, which is used globally to provide simple, comparable and objective measurements of the built-in safety of road segments for road users. These ratings are given to governments and other users to inform infrastructure and other road safety programs. Recently, the Star Rating methodology has been adapted for the Star Rating for Schools (SR4S) mobile application (an app), which is designed to measure and communicate road and pedestrian safety risks that children and adolescents are exposed to on their journey to and from school. iRAP has brought together several organizations, including Safe Kids Worldwide (SKW), from around the globe to pilot test the SR4S app.
This project, in collaboration with SKW, aims to test the reliability of the SR4S app to answer the following questions: 1) Does the SR4S app produce consistent Star Ratings for the same road segments across multiple users? 2) Does training app users increase the reliability of the SR4S app to assess road and pedestrian safety in local school zones?
Data collection took place during a two-day workshop in Washington, D.C., where 9 child injury experts with experience working in pedestrian safety advocacy (i.e. Safe Kids Coordinators) conducted multiple safety assessments using the SR4S app at a local elementary school at 10 road segments and received training on how to use the app. Data was collected once before training, and twice post-training. This data is currently being analyzed for inter-rater reliability and test-retest reliability. Preliminary results: only 5 of 9 users fully collected the required data and this greatly reduced the reliability of the app. The results of the reliability analysis will be presented to iRAP and the SR4S app developers to inform the development of improved versions of the app which will eventually be rolled out for worldwide use.

Reliability Testing of the Star Rating for Schools (SR4S) Mobile Application: Results from a pilot study
