Abstract: Methods and systems for creating an approach map for a traffic signal preemption controller. A road map is displayed, and in response to user input for instantiating a first segment of an approach map, a first instance of a graphical object overlaying one of the plurality of roads is displayed. The one road represents an approach road to an intersection having the preemption controller. First segment location data that describes a first geographical area bounded by the first segment are determined from size and placement of the first instance of the graphical object on the road map and from location data associated with the one road. The first segment location data are stored in association with the approach map for the preemption controller. The preemption controller, once configured with the first segment location data, initiates traffic signal preemption in response to a preemption request transmitted from within the first geographical area described by the first segment location data.
Abstract: Mobile systems are provided for charging electronic toll collection accounts for parking fees. The systems are configured to wirelessly request and receive tag data from an electronic toll device. Some embodiments include a vehicle and a boom, some embodiments include a handheld device, and other embodiments include combinations thereof. Methods of charging an electronic toll payment system are also provided. A mobile scan system wirelessly requests and receives tag data from an electronic toll device on a customer's vehicle which is checked for validity, and then an electronic toll collection account is charged a fee for parking.

Abstract: LED traffic light 30 having a housing 39 that holds at least three different signal lights 32, 34, and 36. The three lights 32, 34, and 36 are each embedded in an opening 50 of housing 39. The LEDs for traffic signal lights 32, 34, and 36 are arranged in symbolic shapes (i.e. universal symbols or words) that further represent one of the traffic signals. Red signal light 32 has red LEDs 31 arranged in an octagon shape (i.e. stop sign shape), and yellow or amber signal light 34 has yellow LEDs 33 arranged in a triangle shape (i.e. caution sign shape). Green signal light 36 has green LEDs 35 arranged in a circular shape. The preferred embodiment is a single lens traffic light 40 having a housing 49 that provides at least three signal lights 42, 44, and 46. The three signal lights 42, 44, and 46 are all embedded in a single opening 50 of housing 49.
