The Dabbawallas - a unique food delivery system in Mumbai. A dabbawalla means "person with a box". A Dabbawalla is employed in a unique service industry whose primary business is to collect the freshly cooked food in lunch boxes (tiffins) from the residences of the office workers in the suburbs at 9am and deliver them to their respective workplaces in the city by 12:30 pm and finally returning the empty boxes back to the customer's residence using various modes of public transport ranging from bicycles to trains. The unreliable transport system with frequent congestions would be a problem with over 200,00 meals to be delivered. The Dabbawallas have a reputation of being the most effective delivery force in India. This highly specialized trade is over a century old, founded in 1890 and has become an integral part of Mumbai's culture. The Dabbawallas claim to have an error rate of 1 in 16 million delivery’s and have a strong solid relationship of trustworthiness with their clients. With the ability to reach 200,00 people a day large corporations are keen to get in on the action.

Cycling in Copenhagen is an important means of transportation and a dominating feature of the cityscape often noticed by visitors. The city offers a variety of favorable cycling conditions — dense urban proximities, short distances, and flat terrain — along with an extensive and well-designed system of cycle tracks. This has earned it a reputation as one of the most—possibly the most—bicycle-friendly city in the world. Being environmentally friendly, cheaper, and often a quicker way to navigate around town than other public transport means like cars, etc. it is, therefore, a city goal to support bike commuter travel by 50% by the year 2015.
