Abstract: A roadway monitoring camera cleaning system includes one or more cameras for capturing images through respective viewing surfaces, which are exposed to outdoor environmental conditions. A controller coupled to the cameras receives the images and determines whether a predetermined wash threshold has been met based on any of various indicia of image degradation. Responsive to the wash threshold being met, the controller operates a supply valve to connect a wash fluid source to a conduit, and operates at least one delivery tube valve to connect the supply conduit to at least one delivery tube. Wash fluid is delivered under pressure to the dirty viewing surface as a result. Subsequently, the controller may disconnect the wash fluid source and connect a pressurized source of inert dry gas, in order to dry the viewing surface and to purge the delivery tube of wash fluid.

Abstract: A method and system for the electronic payment of unpaid or missed tolls utilizing a web-based system that records information relating to the unpaid or missed tolls and provides access to drivers or customers to a website whereby drivers/customers can electronically arrange for non-cash payment of unpaid or missed tolls. The method and system also allows for the ability to audit various types of information relating to such payments, to remove or delete information relating to violations when payment has been made and to generate various reports for accounting, financial, enforcement and other operational purposes.
