Autonomous and Dependent Data Collection for Traffic Analysis
First Claim
1. A bandwidth efficient method for gathering traffic data over a wireless network, the method comprising the acts of:
- collecting data autonomously at a first one of a plurality of in-traffic probes, wherein the in-traffic probe is associated with a mobile vehicle, comprises a sensor and is configured to autonomously perform actions to;
control the rate and type of data collection;
record collected data, wherein the collected data is uniquely attributable to the traffic probe and sufficient to support a derivation of traffic related data;
derive traffic related data; and
transmit the traffic related data to a central processor;
the first in-traffic probe reporting the traffic data, via a wireless network, to a geographically stationary central control system;
the central control system receiving traffic data reports from the first one of a plurality of in-traffic probes;
the central control system sending, via the wireless network, a control signal to a second one of a plurality of in-traffic probes; and
in response to receiving the control signal, the second in-traffic probe commencing the reporting of traffic data via the wireless network.

Abstract
A central control system operates in conjunction with multiple mobile traffic probes to analyze and characterize traffic in a particular region or area. The traffic probes operate autonomously to collect traffic related data and report the collected data to the central control system. The traffic probes can analyze the collected data to identify traffic anomalies, and in response, change the amount and type of data collected, as well as the frequency of reporting the data to the central control system. In addition, the central control system can analyze the received data to identify traffic anomalies or points of interest and force one or more deployed traffic probes to change the amount and type of data collected, as well as the frequency of reporting.

8. A bandwidth efficient method for gathering traffic data over a wireless network, the method comprising the acts of:
-
collecting data autonomously using at least one in-traffic probe, wherein the in-traffic probe resides in a mobile vehicle, comprises a sensor, a data storage and a processor and is configured to autonomously perform the acts of; periodically at a first rate, via the sensor, collecting at least one data type; tracking, via the processor, the collected data; comparing, via the processor, each newly collected datum to previously collected data, wherein an anomaly is identified if a newly collected datum has a value that is determined to be outside an expected deviation from previously collected data; subsequent to identification of an anomaly, recording data collection to the data storage, wherein the collected data is sufficient to support a derivation of traffic related data; deriving traffic related data; characterizing the traffic related data into a traffic conditions report; and transmitting the traffic conditions report, via a wireless network, to a geographically stationary central control system; wherein wireless network bandwidth is only consumed in the event that an anomaly has been identified. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
