Benefits of technology
[0122]Preferably, the data structure also includes a module for indexing a list of one or more authorization levels for each remote monitoring recipient. These authorization levels may be used to impose conditions on the managed object values being conveyed to the recipient. Some recipients may be entitled to all of the managed object values, others to only some of the them, and still other requesting entities (those not in the list) entitled to none at all.
Problems solved by technology
However, these systems are relatively expensive to operate.
The operating platforms tested thus far by CARB have been relatively cumbersome and have limited capability to be used for other data exchange needs in the future.
Vehicular traffic has become a major problem for urban planners.
It is also known that the actual volume of traffic handled by a thoroughfare plummets when traffic becomes congested.

Embodiment Construction
[0147]Described herein below is a system and method which implements a peer-to-peer Internet-based protocol stack for vehicular diagnostic telemetry. This stack is intended to reside in on-board vehicular embedded systems and to enable remote PC workstations to interact with these systems using standard communications API's such as Winsock.
[0148]The Session and Presentation layers of the stack are labeled the Automotive Telemetry Protocol (ATP). ATP addresses the need for a clear specification of the message formats, protocol procedures, security mechanisms and external interfaces by which software can be developed for implementation of OBD-III1 on different mobile and fixed computing platforms in an inter-operable fashion. 1On-Board Diagnostics III. Proposed legislation, spearheaded by the California Air Resources Board (CARB) requiring emissions-related diagnostic information from Engine Control Modules (ECM's) in vehicles to lend itself to retrieval over mobile communications net...

Abstract
Disclosed is a method of conveying vehicle operation data from a vehicle to a remote monitoring recipient, comprising the steps of establishing a data link between the vehicle and the remote monitoring recipient; collecting vehicle operation data from data sources in the vehicle; packaging the vehicle operation data in a data packet using protocol derived from SNMP; and conveying the data packet over the data link.
