Abstract
A roadway information system is disclosed with components generating and using vehicle signatures for vehicles passing near sensor pods located on or near lanes. Means and/or processors for matching incoming and outgoing vehicle signatures are disclosed creating an in-out vehicle match table used to generate a vehicle movement estimate or its components including a travel time and/or vehicle count.
Claims32
Apparatus, comprising a generating processor (60) configured to access
- a list (25) of incoming vehicle signatures (26) based upon sensor readings (22) of a first sensor pod (20) of incoming vehicles (6),
- a list of outgoing vehicle signatures based upon said sensor readings of a second sensor pod of outgoing vehicles
- to create an in-out vehicle match table 32 to estimate a travel time (82) between said first and said second sensor pod and
- a vehicle count (84) of said vehicles passing between said first and said second sensor pod;
- and
- wherein said apparatus further comprises at least one of
- a server containing an installation package and configured to communicate said installation package to a processor to affect a configuration of said generating processor;
- and
- a computer readable memory configured to affect said configuration of said generating processor.
6 more elements
A method, comprising the step of:
- operating a processor;
- and wherein said method further comprises at least one of the steps of
- operating a server to deliver an installation package for installation on said processor in support of said step of operating said processor;
- and
- using a computer readable memory to support said step of operating said processor;
- wherein the step of operating said processor, comprises at least one of the steps of:
- matching incoming vehicle signatures to outgoing vehicle signatures to create an in-out vehicle match table;
- matching said outgoing vehicle signatures to said incoming vehicle signatures to create said in-out vehicle match table;
- and
- matching all of said incoming vehicle signatures and said outgoing vehicle signatures to create said in-out vehicle match table.
7 more elements
Apparatus, comprising:
- means for matching (110) configured to access
- a list (25) of incoming vehicle signatures (26) based upon sensor readings (22) of a first sensor pod (20) of incoming vehicles (6),
- a list of outgoing vehicle signatures based upon said sensor readings of a second sensor pod of outgoing vehicles
- to create an in-out vehicle match table (32) to estimate a travel time (82) between said first and said second sensor pod and
- a vehicle count (84) of said vehicles passing between said first and said second sensor pod;
- and
- wherein said apparatus further comprises at least one member of the group consisting of
- a server containing an installation package and configured to communicate said installation package to at least partly configure said means for matching;
- and
- a computer readable memory configured to said at least partly configure said means for matching.
