During congested periods in urban areas, traffic flows are higher and traffic speeds are lower than during uncongested periods. In such conditions there are likely to be more accidents but fewer, or less severe, casualties than in uncongested periods. The study focused on child, adult and elderly pedestrian accidents in relation to the existing spatial patterns of urban land use in the city centre during congested periods (7.00am — 8.00pm) and uncongested periods (9.00pm — 06.00am). Generalised Linear Models (GLMs) were constructed using the number of pedestrian accidents including these three age groups as response variables with census and land use data as explanatory variables. The analysis shows that retail land use may have the same influence on adult pedestrians during both congested and uncongested periods on weekdays. On average, an increase of retail land use by 1% in urban area will increase adult pedestrians by 30% during weekdays.
