Methods, systems, and computer program products for determining transit routes through crowd-sourcing, for determining an estimated time of arrival (ETA) of a vehicle of the transit route at a given location, and for providing predictive reminders to a user for catching a vehicle of the transit route. A server receives signal source information about wireless signal sources detected by user devices, including information about a first wireless signal source detected by some devices. The server determines that the first wireless signal source is moving. The server determines that the first wireless signal source is associated with a public transit route upon determining that the signal source information satisfies one or more selection criteria. The server stores information associating the first wireless signal source with the public transit route as transit movement data corresponding to the public transit route.

Embodiments are directed to a system for implementing a restricted-operation region. The system includes an instruction development module configured to be utilized in the development of a set of instructions that implement an operation policy of the restricted-operation region. The set of instructions is configured to, when interpreted, implement the operation policy by controlling at least one function of a vehicle that attempts to operate within the restricted-operation region. The system further includes a first transmitter configured to transmit the set of instructions to the vehicle, wherein a processor of the vehicle is configured to interpret the set of instructions based at least in part on a determination that the vehicle is attempting to operate within the restricted-operation region.

Biometric monitoring devices, including various technologies that may be implemented in such devices, are discussed herein. Additionally, techniques, systems, and apparatuses are discussed herein for providing power-conserving techniques and systems for efficiently utilizing a GPS receiver are described. The positional fix frequency of the GPS receiver may, according to some implementations, be modified or adjusted between various levels according to data from one or more non-GPS sensors. Such non-GPS sensors may include, for example, ambient light intensity or spectrum sensors, accelerometers, gyroscopes, magnetometers, heart rate sensors, galvanic skin response sensors, infrared sensors, etc.
