Methods and systems for determining information relating to the operation of traffic control signals
First Claim
1. A method for determining information relating to the operation of at least one traffic control signal, the traffic control signal being operable to transition between different phases in use, the method comprising:
- obtaining data indicative of the durations of multiple instances of at least one phase of the traffic control signal;
using the obtained data to determine, by a processing device, for the or each phase, data indicative of a distribution of the durations of the multiple instances of the phase;
using the determined distribution data to obtain, by the processing device, data indicative of a probability of the traffic control signal having a given phase at one or more future times; and
using the data indicative of the probability of the traffic control signal having a given phase at one or more future times to determine and output one or more of;
a route, a travel time, a speed recommendation, an expected waiting time, and an expected queue time.

Abstract
Data indicative of the durations of multiple instances of different phases of a traffic control signal in a given time period is determined. The data is used to obtain data indicative of a distribution of the durations of each phase. The distribution data is used to obtain data indicative of a probability of the traffic control signal having a given phase at one or more future time. The probability data may be used to provide an expected waiting time when arriving at the signal at a future time and/or a speed recommendation for a vehicle approaching the signal.

16. A system for determining information relating to the operation of at least one traffic control signal, the traffic control signal being operable to transition between different phases in use, the system comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:
-
obtain data indicative of the durations of multiple instances of at least one phase of the traffic control signal; use the obtained data to determine, for the or each phase, data indicative of a distribution of the durations of the multiple instances of the phase; use the determined distribution data to obtain data indicative of a probability of the traffic control signal having a given phase at one or more future times; and use the data indicative of the probability of the traffic control signal having a given phase at one or more future times to determine and output one or more of;
a route, a travel time, a speed recommendation, an expected waiting time, and an expected queue time.
