3.2. Accessibility Accessibility is often used in human geography for the evaluation of spatial distribution of facilities and functions. A place is accessible only when it can be reached easily by pedestrians or by an appropriate mode of transport; it denotes the ease with which any land-use activity can be reached from a location, using a particular transport system[13]. Accessibility is also considered as the opportunities available to an individual or type of person to take part in a particular activity or set of activities. Therefore an exemplary measurement of accessibility consist of two parts [14]: A. Transportation elements, which represents the impedance or difficulty of travel, usually measured by travel distance, time, or costs …show more content…

One central idea that has become very clear is that meeting one’s daily needs on foot in a neighborhood is made much more convenient and more likely when many-to destinations are clustered close together (Figure 2-9) [15]. According to Newman and Kenworthy a pedestrian catchment area or “Ped shed”, based on a 10 minute walk, creates an area of approximately 2.2-5.5 km2 (walking distance is about 800m – 1300m from the center to the edge) for walking speeds of 5-8 …show more content…

The Urban Village approach claims that the convenient walking distance usually defines the size, a 10 minute walk from one side of the urban area to the other (up to 900 m across) [18]. Thus an urban development area could be around 0.4 km2 say 600x600m , the maximum distance between the dwelling and different services as shown in (Figure 2-14); it illustrates that the comfortable walking distance is between 800 m to 1600 m; and using the car if the travel time is between 30 minutes to 1 hour 30 minutes44, that there is an approval that the walking distance between the services and any dwelling in a neighborhood must not exceed 10 to 15 minutes which refer to 400 m to 800 m (figure
