Simplified planning of schedules and duty rosters

Rhein-Neckar AVLC with TETRA-Motorola Digital Radio System

The AVLC of the Rhein-Neckar-Verkehr GmbH facilitates the joint planning of schedules and duty rosters for the cities of Mannheim, Ludwigshafen, Heidelberg and Weinheim as well as the regions of Rhein-Neckar, Rhein-Pfalz, Bad Dürkheim and Bergstrasse. The central control centre in Mannheim coordinates all routes and is based on a TETRA-Motorola digital radio system.

The system was implemented in two stages. The first stage involved upgrading and installing 20 vehicles with IBISplus on-board computers and commissioning the digital radio system. Stage two dealt with the introduction of AVLC system LIO, complete refitting of the vehicle fleet, digital passenger information, duty planning and the interface to driver scheduling.
