A colour-coded map of Greater London shows the percentage of an area's workday population that arrives by train. In general, the closer to the core, the higher the percentage. When the mode of travel is the underground, the highest percentage shifts to Oxford Circus, another map shows the percentage of the population that arrives in an area by foot. The percentages illustrated by gradated colour are dramatically lower when the map shows the percentage who arrive by bicycle. The usage remains low, especially far from the core. The colour-coded map of Greater London now shows the percentage of an area's residential population that departs by train, which is universally low. Higher usage is evident when the mode of travel is the underground network, especially in the outer areas to the west. More people depart by foot in the city of London proper than anywhere else in the region. Residential departure by bicycle is relatively low, though slightly higher in areas to the northeast. Commuter walking times. On a dark map of central London, underground and rail stations are identified. Walkable distances blossom from the stations, according to an accelerated timer, illustrating the statement that 95 percent of central London can be reached within a 15 minute walk from the nearest station when a proposed pedestrian network is added to the map, walking times are reduced.
