Background

Toll-gate is a bottleneck, that normally trigger traffic jam, not only delay passing time, but also increase emissions of CO2. There for, all over the world transportation departments require to adopt non-stop electronic toll collection system (ETC),to stabilize the traffic flow. ETC toll-gate equipped laser detector, for vehicle license plate recognition, using electromagnetic induction lamp technology to confirm vehicles information, also used to detect vehicle model, peccancy, owner's information, balance etc. ETC keeps road clear, reduce passing time and CO2 emissions.

Electronic Toll Collection(ETC) Data Transmission System of Expressway

Requirements

Toll data time ≤0.5s

Toll gate sends system parameter to lane average waiting time≤60s

Lane operation data upload to toll gate database time≤1s

High-reliability, unattended ,MTBF≥10years

High speed data forwarding capability

Solution

Equipped IS2000 switch at toll-gate of expressway, to form redundant ring topology, to ensure at least 2 ways reach to local server from detection node of each vehicle, avoid of link fault effect toll collection system. Each toll-gate uses core IS6000 with multiple GE fiber ports cascade management center, used to upload toll data and to download vehicles update database ,IS2000and IS6000 switches have not only MAC binding, IP binding and ACL strategy technology secure server, and also have QINQ technology to realize expressway VLAN repeat . Primestone switch, ultra short forwarding delay technology between ports, quick response toll request, reduce the toll time, maximum improve throughput rate of Traffic flow .
