In congested cities, especially in central business districts cycling may be the fastest transport option. The bicycle therefore offers time savings and makes it possible to travel more and further. When cycling replaces walking both accessibility and mobility improve. By bicycle one can move easily three times as fast as on foot and thus travel three times as far in the same time. This enlarges the accessible area enormously. With the right accessories, bicycles can also carry a hefty cargo, thus making trips for local shopping, school and other errands much more comfortable.

Bicycles generate no air pollution, no greenhouse gases and hardly any noise (Yazid et al., 2011). …show more content…
Therefore the combination of cycling and public transport provides a good alternative to private mode of travel.
2.3.6 Improving Road Safety and Security
According to the World Health Organization, traffic accidents are the leading cause of death among young people in developing countries. In these countries, the vast majority of traffic accident victims are pedestrians and cyclists. Increasing the share of cycling and providing users with safe facilities can substantially improve road safety.
Cycling can also enhance security in the public domain as it adds to the presence of approachable people on the streets. A critical mass is required for safe streets. (Jacobsen, 2003) found “safety in numbers”, that is “Risks are substantially lower in cities where a higher proportion of the population cycles or walks to work”.

However given the hostile conditions for public transport and increasing risk to pedestrians and cyclists, the use of personal motorized vehicle is increasing. This trend is accompanied with the rise in traffic crashes and deteriorating air quality in cities. Emission levels vary with travel behaviour which is dependent on city size, structure and mode choice available. In Indian cities, a large proportion of population lives in slums, for example in Mumbai percentage of population living in slums is 54.1%, Kolkata 32.5% and in Delhi it is 18.7% (Census of India, 2001). There is a significant proportion of people who cannot afford personal motorized vehicles (cars and two-wheelers) for transportation and subsidized bus systems are also too expensive for them for daily commute (Mohan and Tiwari, 2000). Their transportation needs are thus dependent on NMT (walking or cycling). As such, even in the megacities of India (population more than 8 million), 30% of the trips are made by NMT, 50% by PT (both formal bus systems and informal bus systems, tempos) and rest are by Personal Motorized Vehicles (PMV) i.e. cars and two
