US Patent:

D3159990, Apr 9, 1991

Filed:

Dec 12, 1988

Appl. No.:

7/283518

Inventors:

Thomas L. Bauer - Portland OR

US Classification:

D 6567

US Patent:

20230013604, Jan 19, 2023

Filed:

Sep 17, 2022

Appl. No.:

17/947106

Inventors:

- Beaverton OR, US

International Classification:

G08G 1/08
G08G 1/01

Abstract:

Traffic signal timing plans are derived from vehicle trajectory or probe data. The probe data is collected and archived in a datastore over a sample time on the order of weeks or longer. Probe data is corrected for clock drift, geo-fence filtered to a selected intersection, and then stop line crossings in the intersection are identified and analyzed along with related data to determine the timing plans and schedule for the intersection. In this way, access to government agency timing plans is obviated so as to save time and expense.

International Classification:

G01R 29/18
G01R 19/25
G01R 19/175

Abstract:

A method includes performing by a processor: receiving a plurality of power system synchrophasor measurements over a time interval from a plurality of phasor measurement units (PMUs) in a power system, determining a variation in frequency of a power signal generated by the power system based on the plurality of power system synchrophasor measurements, and determining a clock time shift based on the variation in frequency of the power signal.

Inventors:

- BEAVERTON OR, US
Thomas BAUER - Beaverton OR, US

Assignee:

TRAFFIC TECHNOLOGY SERVICES, INC. - BEAVERTON OR

International Classification:

G08G 1/087
G08G 1/01

Abstract:

At a roadway intersection controlled by an electronic traffic signal controller system, a potentially dangerous “dilemma zone” problem arises where a driver must quickly decide whether to stop or continue through the intersection. The problem is mitigated by leveraging data provided by an approaching vehicle itself as the source of detection. Based on the vehicle data itself, an “artificial detection” message is sent to the traffic signal controller to attempt to extend the green time, and thus permit a subject vehicle to safely pass through the intersection.

International Classification:

G08G 1/01
G08G 1/0967
G08G 1/123

Abstract:

Methods and systems to improve the accuracy of traffic signal state change predictions are disclosed. Predictions can be broadcast to vehicle drivers or autonomous systems to improve safety, fuel efficiency and reduce delays. Predictions for fixed-time signals are generated based on their scheduled timing plan and the current clock/time, but these predictions are subject variations, for example, due to traffic signal controller clock drift. Real-time actual, not predicted, data is collected and utilized to correct for these variations. Further, real-time probe data is collected and used to validate correctness of the generated predictions in real time. In one embodiment, GPS data from travelers' devices is utilized to assess validity of the generated predictions, looking particularly at signal stop line crossings relative to predicted green time window. If crossings observed in real time contradict the predicted signal state, the data service providing predictions to users may be suspended.

International Classification:

G08G 1/0967
G08G 1/0962
B60R 1/00
G08G 1/01
G06K 9/00

Abstract:

Computer-implemented predictions of upcoming traffic control signal states or state changes can be used to improve driver convenience, safety, and fuel economy. Such information can be used advantageously by a human operator, or by an autonomous or semi-autonomous vehicle control system. Predictions can be computed with suitable machines installed in a vehicle, in cooperation with a remote back-end server system. The prediction computations in the vehicle may be supported by data communicated to the vehicle computing machinery over various wireless communications, including telecom systems, DSRC, etc.
