| + | === Experiment Notes === | ||
| + | |||
| + | The experiment was conducted in the afternoon on 11/13/2009. Here are the notes: | ||
| + | |||
| + | Three cars, a prius, toyota sedan, and Nissan Murano drove two routes. | ||
| + | |||
| + | The first route was a loop around vassar and albany between mass ave and main street. The idea was to test communication with tall buildings and parallel traveling between tall buildings. For most of the experiment, two cars went one direction, with some stagger, while the third went the opposite. This experiment lasted around 15 minutes. | ||
| + | |||
| + | The second route was in east cambridge. we looped on hurley street and charles strees between snd and 6th. The cars drove in various directions and various lengths of the loop (i.e, turning down earlier side streets.) This route covered three big and two small residential blocks. The housing was mainly 2 - 3 three story double family units. We drove here around 20 minutes. | ||
| + | |||
| + | Lewis' GPS did not cycle data for the first 20 minutes or so (it started recording right before arriving in East Cambridge.) | ||
| + | Because of this the timestamps are all local. | ||
| + | |||
| + | Sam's box went down on two occasions earlier in the experiment, for around 10 - 20 seconds at a time. | ||
| + | |||
| + | === Experiment Data === | ||
| + | |||
| + | The combined data logs are accessible at: | ||
| + | |||
| + | http://people.csail.mit.edu/cnewport/mobilemesh/data/Nov13/ | ||
| + | |||
| + | The logs labelled ''final'' are combined, sorted by time, and logged with position. For entries that do not have corresponding positions, -1 -1 is used as a default. For the Car 2 log the timestamps were manually fixed to real time (in this car, the GPS didn't work for the first 20 minutes, so all log entires had only a local time stamp.) | ||
