  2. nike experiment using GPS…

  3. USING CELLPHONE ACTIVITY TO DESCRIBE CITIES A PROJECT IN MILAN (ITALY)

  4. in spring 2004 the lab started a joint venture with one of the leading european cell phone companies. the research goal: use location data from cell phones to map the city [CONFIDENTIAL]

  5. location based services / lbs are a set of applications that exploit the knowledge of the geographical positions of a mobile device in order to provide services based on that information

  6. individual users as beneficiaries • navigation aids • routing and multi-modal routing • yellow pages • education Services • distributed chats • friend tracking • traffic Services • urban showcase (urban tapestries) • public safety and security • family security • business safety • commercial and information services • location sensitive billing groups of users as beneficiaries third parties as beneficiaries

  7. LBS have not yet been used at an aggregated level to describe cities

  8. DATA BASE:absolute values(ERLANG) SITE: signal coverage area all around a base station (about 500m) 232 sites = 1071 cells (sectors)

  9. /1 antenna activity /2 traces of the city

  10. /1 antenna activity /2 traces of the city

  11. CELL ACTIVITY – ABSOLUTE VALUES (ERLANG) T R A F F I C U N I T : E R L A N G- the hourly average occupation of the radio channels 1ERLANG OF TRAFFIC=1 CALL x 60 MIN =2CALLS x 30 MIN =120 CALLS x ½ MIN 19th April 2004 – Milan Metropolitan Area

  12. DATA BASE: relative values normalized respect to: ROWS:SITE id - average of activity during the day (the totality of hours) COLUMNS:HOURS of the day - average of activity for the whole region (the totality of cells)

  13. CELL ACTIVITY – group of cells with prevalence of activity during the office hours CRITERIA: respect to the daily average, the gap of activity from 9 am to 1 pm and from 2 pm to 6 pm is more than +20% The graphic below is based on relative values normalized respect to: the average of activity during the day (the totality of hours) for each cell the average of activity for the whole region (the totality of cells) for each hour of the day 19th April 2004 – Milan Metropolitan Area

  14. CELL ACTIVITY – group of cells with prevalence of activity during the evening and night time CRITERIA: respect to the daily average, the gap of activity from 8 pm to 8 am is more than +60% The graphic below is based on relative values normalized respect to: the average of activity during the day (the totality of hours) for each cell the average of activity for the whole region (the totality of cells) for each hour of the day 19th April 2004 – Milan Metropolitan Area

  15. CLASSIFIED CELLS CRITERIA: the intensity of activity (respect to the average) during different hours of the day - activities are classified in: 1 WORKING HOURS HIGH ACTIVE 0 UNCERTAIN -1 WORKING HOURS LOW ACTIVE WORKING HOURS = from 9 am to 1 pm and from 2 pm to 6 pm CLASS id = 1 if the gap is > 10% and -1 if the gap is < - 10%

  39. iSPOTS How Wireless Technology Is Changing Life On The MIT Campus CUPUM05, London, UK >MIT SENSEable City Laboratory Andres Sevtsuk; Carlo Ratti team:Xiongjiu Liao; Jia Lou;David Lee; Daniel A Gutierrez; Sonya web.mit.edu Context / Test environment / Data/ Preliminary data interpretation / Conclusion

  40. >MIT campus Location: Boston, MA Area: 168 acres People: 10, 320 students and 9, 414 total employees Buildings: over 190 Context / Test environment/ Data/ Preliminary data interpretation / Conclusion

  41. >wireless on MIT campus - projected date of 100% wireless coverage on campus: October 30, 2005 - number of current wireless access points: circa 2300 - number of access points monitored by the iSPOTS project: 1614 948 APs in academic buildings, 124 in service buildings and 326 in residences. - number of different buildings monitored: 104 Context / Test environment/ Data/ Preliminary data interpretation / Conclusion

  42. Context / Test environment/ Data/ Preliminary data interpretation / Conclusion
