Re: [ipwave] Protocols and Architectures for Traffic Lights

[Alexandre Petrescu <[e-mail]>]

Traffic Light EXchange platform (TLEX) is a protocol about which people 
in countries like Netherlands and Finland talk, together with the 
acronyms iVRI and IVERA.

Manufacturers: SWARCO, Dynniq, Siemens.
