title: Are elderly pedestrians allowed enough time at pedestrian crossings in Cape Town, South Africa?
abstract: A descriptive, cross-sectional analytical study was conducted to determine whether the recommended walking speed of 1.2 ms(-1) would allow elderly pedestrians to safely clear pedestrian crossings in Cape Town, South Africa. Male and female volunteers (n = 47), aged 65-93 years and resident in four homes for older persons, were recruited. Pedestrian clearance intervals at 40 traffic lights within 5-km radius of the selected homes were measured. The mean walking speed required at these traffic lights was 0.86 +/- 0.32 ms(1). The maximal walking speed over 12 m was measured without carrying any load and when carrying a predetermined weight of an average shopping bag. Participants' emotions associated with pedestrian road safety were also assessed through an interview. The mean maximal unloaded and loaded walking speeds were 1.36 +/- 0.31 ms(-1) (0.73-2.03 ms(-1)), and 1.36 +/- 0.33 ms(-1) (0.58-2.12 ms(-1)), respectively. Over 30% of the participants walked slower than the recommended walking speed of 1.2 ms(-1). Participants felt that traffic lights did not allow for sufficient time to cross roads (51.1%) and reported emotions of apprehension (44.7%), anxiety (17.0%), and fear (10.6%) when crossing. A review of traffic planning and public policy is recommended to ensure older pedestrians safely clear pedestrian crossings.
