“…There is evidence from the study on walking distances to and from light rail transit stations in the city of Calgary, Canada, that average walking distance to light rail stations is 326 m in the CBD area or 649 m in suburban areas. From this study, perception of walk time was found to vary over the walking environment of stations and 80 m/min was adopted to compare the calculated walking distances with the measured walking distances, which was an approximation to a normal distribution (O'Sullivan and Morrall, 1995). Nevertheless, according to RICS Policy Unit Report (RICS, 2002), the impact area for residential developments could extend to 1000 m from a station depending on the type of investment and the size of the urban area (Du and Mulley, 2007).…”
