I need to plan a travel in Greater London (within the M25) over multiple destinations via buses and by walking.
Many online tools, including Google Maps and TFL website, enable finding the best routes between two or more points in the city (with some flexible options such as 'with least walking' or 'with least transfer'). However, their flexibility is still limited. They don't support a highly-customized journey, e.g. a mix of taking buses and walking between destinations.
There is some large printable street maps with buses information in the TFL website but it is not easy to recognize and track routes of buses. Also, there is an interactive bus map that shows only one bus route at a time (it would be great if it shows more than one).
Is there any interactive tool/map that enables 'manual', highly-customized planning of journeys based on mix of buses and walking?
