The main objectives of the present project were to develop software for computer-supported training of primary age children in safe use of the main types of designated pedestrian crossings (pelicans/puffins/toucans, zebras, and junction traffic lights with pedestrian phases); and to evaluate the effectiveness of this training by implementing it with samples of children aged 6, 8 and 10 years, pre-testing these children at the roadside to establish their baseline capabilities, post-testing them to measure changes in performance, and comparing these changes with those exhibited over the same period by untrained control samples of the same age, and with the performance of adults All in all, the results of the evaluation are very positive, and serve to confirm the potential for computer-based training of children in safe use of designated crossings, provided this training follows the appropriate format. Whilst training by no means brought children to ceiling levels of performance, the improvements they exhibited were based solely on two hours activity and were robust enough to show up two months later. At the same time, there is obviously some scope for extending the impact of the training programme.
