KMDA Survey

Client: Kolkata Metropolitan Development Authority (KMDA)


KMDA is the statutory planning and development authority for Kolkata Metropolitan Area (KMA) functioning under the administrative control of Urban Development Department of Government of West Bengal. While constructing a 500-metre, four-lane flyover in Salt Lake, KMDA wished to conduct a survey through which Kolkatans could provide their suggestions for beautification of the Nabadiganta flyover.

To offer a break from the bleak grey structures seen throughout the city, KMDA came up with a unique method of giving the finishing touches. It wanted to color the flyover (single or dual color scheme) but only according to the wishes of the city residents. It also wanted suggestions from the citizens about whether the space beneath the flyover would sport an art gallery or shopping center, or remain a green belt. To this end, KMDA decided to conduct online polls to find out the choice of the city.


Web Spiders proposed a solution that would apply Rich Internet Technologies in order to offer a rich and engaging experience to the survey participants. It would be an application of the Web 2.0 model, where users would be able to participate directly in the decision making process.

The survey page created for KMDA displayed an image of the proposed bridge and different color palettes to choose from. Users could choose separate colors for the body of flyover and its pillars by clicking on the color palettes. A preview was then immediately available as the color changes got reflected in the image.

Apart from colors, users could also provide inputs on utilization of space under the bridge. The responses entered by users were then stored in a backend database. On completion of the survey, the votes were tallied automatically, and the city voted overwhelmingly for its first colored flyover (cream with rust pillars) along with a green zone below the flyover.

“The first reaction to the website created is that it is so very neat and the layout is absolutely uncluttered. It is amazing to see how the colors of the structure change as different choices are exercised. Thanks very much for all the hard work put in by your team.”

- Vivek Bharadwaj, CEO, KMDA
