One or more roadside collection stations (RCS) communicate over a short-range, high speed bidirectional microwave communication link with one or more in-vehicle units (IVU) associated with one or more respectively corresponding vehicles in one or more traffic lanes of a highway. At least two up-link
One or more roadside collection stations (RCS) communicate over a short-range, high speed bidirectional microwave communication link with one or more in-vehicle units (IVU) associated with one or more respectively corresponding vehicles in one or more traffic lanes of a highway. At least two up-link (IVU to RCS) communication sessions and at least one downlink (RCS to IVU) communication session are transacted in real time during the limited duration of an RCS communication footprint as the vehicle travels along its lane past a highway toll plaza. Especially efficient data formatting and processing is utilized so as to permit, during this brief interval, computation of the requisite toll amount and a fully verified and cryptographically secured (preferably anonymous) debiting of a smart card containing electronic money. Preferably an untraceable electronic check is communicated in a cryptographically sealed envelope with opener. Transaction linkage data is utilized in each phase of the complete toll payment transaction to facilitate simultaneous multi-lane RCS/IVU operation. A plaza computer local area network and downlink plaza controller is also used to facilitate simultaneous multi-lane transactions.
An automatic highway toll collection system comprising: a roadside collection station disposed in proximity to at least one respectively corresponding highway lane and having a bi-directional electromagnetic data communication link coupled to a predetermined toll collection zone disposed in proximit
An automatic highway toll collection system comprising: a roadside collection station disposed in proximity to at least one respectively corresponding highway lane and having a bi-directional electromagnetic data communication link coupled to a predetermined toll collection zone disposed in proximity to said at least, one respectively corresponding highway lane; an in-vehicle unit disposed in each of plural vehicles passing along the highway and having a bi-directional electromagnetic data communication link coupled to a predetermined vehicular communication zone that moves with the vehicle and intersects said toll collection zone of the roadside collection station for a limited time period as the vehicle passes along said at least one highway lane; said in-vehicle units each including a smart card containing encrypted data representing pre-stored increments of money; and each said roadside collection station and in-vehicle unit including respective data processing circuits connected to its electromagnetic data communication link for effecting at least the following real-time communication and data processing operations during said limited time period: (a) passing first data from an in-vehicle unit to a roadside collection station to initiate payment of a toll; (b) calculating toll data at the roadside collection station which is based on said first data and passing from the roadside collection station to the in-vehicle unit second data, including said toll data and unique linkage data linking said second data to said first data; and (c) debiting the toll from the smart card at the in-vehicle unit and thereafter passing third data from the in-vehicle unit to the roadside collection station including verification data verifying said debiting and unique linkage data linking said third data to said first and second data.
