Study: cell phones adjusted data bus routes in Africa

The search focused “IBM” on the use of mobile phones data to improve the transportation system in the city of Abidjan

Adopted by researchers at IBM’s data on thousands of mobile phones to develop a model to improve the transportation system in urban areas in the Ivory Coast, to what can be provided at time of travel.

The results of the research new ways to allow urban planners to use mobile data – that accommodates spread in Africa – to design and improve infrastructure.

The research focused on the city of Abidjan, the former capital of the Ivory Coast and its largest city, which is an estimated population of 4.5 million people. And employs 539 large buses, minibus and 5000, and 11 thousand taxi.

And launched the “IBM” on its model name AllAboard. He chose from among 65 possible improvement of transportation in Abidjan. The model proposed to add two new destinations, and expand an existing destinations, including contributing to the improvement of the transport system, and provides 10% of travel time for passengers.

The research was based on monitoring of population movements on the study of call records for nearly half a million phones were randomly selected every two weeks, in the period between December 2011 and April 2012.

The data include the time of sending and receiving a call or short message; terms of reservation with communications tower, showing the approximate location of the user within the vicinity of the tower. And when a person moves to another place and conducted site is recorded calls, according to the new tower.

Although the data are similar raw materials, also can not ensure that all passengers have to or use of phones, but it tracks their movements can be drawn through the sequence of communication.

She says, “IBM” that discussed for the first time used mobile data to improve the transport network within the city, while previous studies used the data to infer the travel destinations and demand rates.

It is believed Francisco Calabrese, a researcher at the IBM lab in Dublin and one of the participants in the research, that the availability of contemporary data on population movements, it will lead to more effective results, allowing optimum conversion methods and reduce travel time and wait.

In the opinion of Oliver Vercir, Chief Scientist Research Laboratory IBM in Dublin, that the combined data mobile phones with other can lead to a form more sophisticated: “If we can mix the data connection with data city as tables dates of buses, were we can change the existing network entirely” .

And participates search within the competition organized by the company “Orange” Telecom as the “data for development” Data For Development , and provided a 2.5 billion from data communications to five million mobile phone in the Ivory Coast, which is the most available of this quality of data, and revised so that it can not identification of users.

The competition aims to find innovative ways to meet the requirements of development. And research participation and exposure Search announces the winner at a conference at the Massachusetts Institute of Technology between the first and the third of May.

Considered “IBM” and other research groups involved that the available data accurate enough to demonstrate the movements of the population. It is expected to contribute data to mobile phones in many areas; adopting research groups to discover emerging ethnic conflicts based on the records of the movements of the person and his dealings over the phone, as well as places of refuge predicted the population in the wake of natural disasters.

The data cell phones a valuable opportunity for developing countries; With regard to improving transportation systems, can be based users Alhoutv equipped with global positioning (GPS) applications, such as “Google Maps” and services sensor traffic, while no data are available sites in the regular phones most prevalent in developing countries only by telecommunications companies, and made available only under special arrangements.

The use of developed countries for travelers opinion polls, which exceeds the physical capacity of the developing countries, at a time of increasing use of mobile phones, and can take advantage of their data in research.
