First Claim
Patent Images
1. A parking management system, comprising:
- a roadside unit having a vehicle occupancy sensor with a zone of detection that corresponds to an individual parking space;
a first RF transceiver having a first antenna configured to substantially radiate towards the individual parking space that is configured to communicate with an in-vehicle transceiver;
a second antenna configured to substantially radiate in a direction of one or more gateways, cellular towers, or parking meters, the direction supporting communication between the second antenna and the one or more of gateways, cellular towers, servers, or parking meters; and
a guidance display indicating a number of parking spaces available in a given zone or direction, wherein the guidance display is updated based on occupancy information for each individual parking space collected by the roadside unit.

Abstract
A parking management system that facilitates motorist guidance, payment, violation detection, and enforcement using highly accurate space occupancy detection, unique vehicle identification and guidance displays is described. The system enables reduced time to find parking, congestion mitigation, accurate violation detection, and easier enforcement, and increased payment and enforcement revenues to cities. A system facilitating intersection management is also described having applicability to road intersections and railway crossings.

11. An intersection traffic management system, comprising:
-
at least one first radar sensor, comprising a time of flight or FMCW radar sensor, positioned upstream of an approach to an intersection near locations where vehicle queues can form to detect the vehicle queue length of queues and clearance time of the detection includes one or more of vehicle count, vehicle type, and vehicle classification data; an intersection controller wirelessly coupled with the at least one first radar sensor, either directly or through a gateway, to receive information regarding the vehicle queue to calculate a clearance time based on the received information, and the intersection controller being configured to control a status of one or more signals at the intersection and sequence the one or more signals using the information provided by the at least one radar sensor to optimally route traffic through the intersection. - View Dependent Claims (12, 13, 14, 15, 16)

17. A system for railway crossing intersection management, comprising:
-
a first sensor, comprising a time of flight, FMCW, or Doppler radar sensor, configured to detect a train approaching a railway crossing intersection, the first sensor being installed in a location corresponding to at least one direction of train travel on a railway track; a second sensor, comprising a time of flight or FMCW radar, optical, infrared, or thermal sensor, configured to detect vehicles, persons, or objects at the intersection; a processor, that is configured to receive information from the first sensor and the second sensor, and that is further configured to calculate a potential access conflict or a collision possibility; and one or more signals, located at the intersection, comprising at least one of a auditory signal and a visual signal, that is directed towards the railway crossing intersection. - View Dependent Claims (18, 19, 20)
