4. Public transport is incompatible with low density and dominantly polycentric urban structures. Bus stops and railway stations should be simply accessible from homes or workplaces and walking speeds don't exceed 4.5 km/hr. Acceptable walking distances vary with cultures and incomes, however varied surveys have shown that city dwellers opt to avoid walking for quite ten minutes. As a result, transport stops have an 800 metre catchment area, which may be extended using feeder systems, usually minibuses or collective taxis. however this type of arrangement provides rise to classic inter-modal problems: lost time, will increase in direct prices if the system isn't price-integrated, need for specific commutation infrastructure in order that necessary investment prices are accumulated.
Be that because it might, as such, investment in public transport infrastructure is just economically excusable if housing and employment density is adequate among the catchment area of the stops. As a result, a consensus is rising between researchers and urban planners on a density pertinence threshold for public transport of roughly thirty inhabitants/ha.
5. London bridge: It is a historic bridge with 5 lanes constructed between the city of London and Southwark over river Thames. which opened in 1973 for traffic and it is a box girder bridge. replaced from stone arch bridge to concrete and steel. I think its lifespan is 600 years old. this bridge was constructed by Romans i.e. piled bridge after the area became popular at Southwark. but it collapsed in the middle and rebuilt by Romans again. this area became popular by developing the business over trading and shipping. and it is convenient to seagoing trade between Britain and the Romans empire. at present, it is also a tourist attraction.
