Panasonic introduced the P2 recording format in 2003, which used solid-state memory for recording either SD or HD digital video and audio, and had the advantage of containing no moving parts. The recorder used up to five Secure Digital flash memory plug-in cards. Signals were recorded with DV or DVCPRO compression. P2 was available as a camcorder and studio recorder. Both supported MXF file transfer (see later section) and were intended to be part of an integrated system for managing digital content.

P2 is a solid-state recording device similar to the Flash memory used by digital still cameras. The P2 uses the PC-card footprint so it can be taken from the camera and plugged into a laptop for immediate editing in the field. In 2006, the cards were 4-GB and 8-GB capacity and, being expensive, they have to be reused. The source files are archived on some other medium.

We calibrate users’ utility (Equation (7)) to fit observed user-route matches. For this purpose, we divide the data into a training dataset (first 80% rides (213 commuting periods)) and a test dataset (remaining 20% rides (remaining 22 periods)). The calibration consists of two steps. The first step consists of estimating the value of in-vehicle travel time (VOT). The estimated VOT can then be used to estimate users’ generalized travel costs. The second step consists of calibrating the users’ utility values to fit observed user-route matches (i.e. user-used route pair) over the studied period. We use the commercial solver intlinprog of MATLAB to solve the P1 and P2 problems based on a Dell Latitude E5470 laptop with win64 OS, Intel i5-6300U CPU, 2 Cores and 8GB memory.
