The maps of pedestrian accessibility are little known in cartography, even through their significance for urban geography and cartography, and particularly for regional planning, is great. The starting quantity is the speed of pedestrian traffic, which depends on many factors; commonly 4 or 3.6 km/h is assumed. On the areas of towns a number of accessibility objects can be found along with possible application of cartographic methods. Examples of various possibilities of such applications are given with reference to the capital city of Prague. Pedestrian accessibility should be presented by diverse screen kind molten into the street network (cf. Fig. 1) which depicts the downtown accessibility („Na můstku”, i.e. „On the viaduct” intersection); accessibility zones of post offices (according to the urban standards of a 600-m radius) is illustrated in Fig. 2. The radius of the circles should be reduced by 83%, as it is not the straight-line (air line) that is involved here. The circular isochrone of a value of 5 min has a radius of 277 m (cf. accessibility of the underground stops at the city center (Fig. 3)). The method of circles and the method of marking in the street network, shown for comparison of similar cases (accessibility of the downtown department stores expressed by the 2-, 4-, and 6-min isochrones) are illustrated in Figs. 4 and 5. The shopping streets should be marked with a line (Fig. 6). The speed of pedestrian traffic is highly affected by sidewalk capacity and the number of persons walking. The maximum traffic occurs at the afternoon rush hours (cf. Fig. 7). More interest should be paid to pedestrian accessibility studies in future, as it affects strongly the people’s life in towns.
