WAZE - Maps and Traffic Information

Traffic jams are one place where you can count on people having unexpected free time. Instead of sitting idly, Waze is using crowd sourcing which allows users to report traffic problems to other app users.

Even when out of a jam, just having the app open adds map and traffic information. The company creates its maps by tracking GPS on users’ phones. It allows other users in the area to see when traffic slows or if somebody reports an event — like an accident, construction, or speed trap — that might affect a specific route.

Nothing can beat real people working together. Imagine 30 million drivers out on the roads, working together towards a common goal: to outsmart traffic and get everyone the best route to work and back, every day. This app will alert you before when you are approaching police, accidents, road hazards or traffic jams, all shared by other drivers in real time. It's like a personal heads-up from a few million of your friends on the road.

The automated system isn’t perfect, but drivers can flag errors, like missing roads, for people to correct online. They can also log in on the web after they’re home and correct the errors they’ve flagged.

Waze also provides an opportunity for individuals to earn online fame. Points are rewarded for miles driven, reporting traffic events, adding house numbers to maps, and mapping new roads. More points equal a better star ranking, which increases privileges to edit maps for roads that the user hasn’t driven on and to correct other users’ errors. Those with the most points earn a position in the site’s Hall of Fame.

WIKIPEDIA – Online Encyclopedia Wikipedia is one example of successful crowdsourcing implementation. It is a free encyclopedia which entries written by experts who undergo a meticulous submission process before their work could be published. It uses such meticulous submission process to keep the validity level of their articles. All of the information in Wikipedia is not only used by a huge crowd of people, but has also been created by the crowd. Wikipedia is a project based on the crowdsourcing model, in which tasks traditionally performed by employees are turned to the Internet multitude, or the crowd.

In order to continuosly verify and enriched the information, if you read an article and notice something wrong or if you have more information on

the subject, you can hop on and edit the article or provide more in-depth explanations. But, on the other side, because of this feature the articles

are also exposed to vandalism.

An early study conducted by IBM researchers in 2003 concluded that vandalism on Wikipedia is usually repaired extremely quickly, so most users

will never see its effects. Another study published by Nature in 2005 showed that for scientific articles Wikipedia came close to the level of

accuracy in Encyclopaedia Britannica and had a similar rate of serious errors.

This shows the great potential and power of the crowd. With the tools that we have available now, in the Internet Age, with groups being able to

come together and communicate easier than ever before, it is amazing to see big projects being so easily accomplished.

QUORA – Question and Answer Quora, the social Q and A platform, is beginning to get its sea legs. There are so many ways to use Quora, well beyond just asking

and answering questions. Some people like to answer and ask questions. Others like to vote on answers or neatly file similar

questions into "topic". Still, others bypass the Q and A platform and use Quora to private message other users who often have

similar interests. How do you fit into the Quora World?

Quora is a social networking website with a difference. It is a combination of Wikipedia and Facebook. The website allows people to

post questions on any topic and get answers from the experts in that field. Till recently it was mostly used by people in the IT field,

especially those in Silicon Valley. So it became more of a networking forum and a way to increase one's own visibility among

potential venture capitalists for startups. For some users, the site is a way to highlight their resume by giving out detailed answers to

show their skills.

In fact, most of the questions seem to revolve around startups, which is among the most popular categories on the site. This is one

of the site's main drawbacks. It has a very narrow focus and hardly covers matters that are not connected to Silicon Valley in some

way. Quora's challenge is to expand on to other fields without alienating its original user base and to keep the quality of its answers

high. Right now, several Silicon Valley executives answer the questions, disclosing their full name and a short job profile. This has

resulted in the site having a high creditability among its followers.

Street Bump – Boston’s Pothole Crowdsourching Street Bump is a crowd-sourcing project that helps residents improves their neighborhood streets. Volunteers use the Street Bump

mobile app to collect road condition data while they drive. The data provides governments with real-time information to fix

problems and plan long term investments.

Volunteers use Street Bump to record "bumps” which are identified using the device's accelerometer and located using its GPS. Bumps are uploaded to the server for analysis. Likely road problems are submitted to the City Government, so they get fixed (e.g. potholes) or classified as known obstacles (e.g. speed bumps).

This Android app uses the accelerometers and GPS technology in users’ phones to register when and where the user’s car has

experienced a pothole. Ultimately, the city’s goal is to use Street Bump data to determine where potholes and other dangerous

street features are located so that steps can be taken to address them quickly.
