74 CHAPTER 7  DATA COLLECTION

Figure 7.1 – Data Collection Setup

Step 1: Conﬁgure Data Storage

e Interval (Bin) Size option species the interval of time over which trac variables

like volume, speed, occupancy and classication are aggregated. is type of data is called

interval data. e minimum interval allowed is ve seconds.

By default, the checkbox next to Memory Overwrite is checked. is means that your

study will run indenitely and repeatedly overwrite the ash memory onboard storage.

is means that in order to not lose collected data, you must download it to a log on your

computer before it is overwritten.

Alternatively, you can uncheck the Memory Overwrite checkbox. In this case, the study

will run only until the sensor’s ash memory has been lled with interval data.

Note

Once the ﬂash memory buer is full, it must be erased before it can be reused. Before

you erase the stored data, you will want to download the data to a log ﬁle on your

computer.

e third line under Step 1 displays the Flash Storage Time. is shows the duration of

interval data that a full ash buer holds, calculated for you as a number of days and hours.

Because of the way ash memory is managed, the Flash Storage Time will vary based on

whether or not you have Memory Overwrite enabled.
