【Traffic systems on an expressway】

《Varied technologies of the ITS.》

The ETC is an abbreviation of electronic toll collection system,according to what is called ウィキペディア.😃

It's only one cellphone which I have.I have neither PC nor other cellphone,so when coming across a phrase of which abbreviation I'm not sure,I can't research.😚

As you know,the ETC has already turned to practical use in the expressway.To be exact,when driving,we can pass through a tollhouse with the ETC card and the device on a car,but its toll is paid from bank account later.🚌

②AHS is also an abbreviation of automatic helpful system,I'm wondering.😚

The AHS is lane markers which are installed on traffic lines on the expressway.It watches us drivers whether or not we drive on the traffic lines correctly.🚌

When driving,if our cars happen to swerve ずれる from the traffic lines,a sensor detects it,and the device let us know it.😲
