1996

The impetus for the founding of the ODG came from the German operators of traffic systems and the Federal Highway Research Institute (BASt). The strategy was to create an industry standard together with the German market leaders.

1999

The signal construction companies Dambach, Siemens, Signalbau Huber, Stoye and Stührenberg founded the working group ODG (OCIT Developer Group).

 

The aim of ODG was and is to standardize interfaces for traffic engineering systems.

The name of the interfaces is:

OCIT (Open Communication Interface for Road Traffic Control Systems / Open Traffic Interfaces)

 

Shortly after the founding of ODG, the customers organized

Operator in the OCA (Open Traffic System City Association e.V).

 

From the beginning it was thought to involve the customers / operators in the form of a "round table" in the standardization. The Round Table consisted of ODG, OCA, VIV and BASt.

2002

Appearance of the first OCIT outstations version 1.0

2003

ODG's cooperation with the Round Table was regulated in the form of a Memorandum of Understanding (MOU).

2003

A new member of the roundtable was OTEC, an OCA-based grouping of manufacturers of central facilities, especially engineering workplaces.

2003

In February 2003, an OCIT working group "OCIT-LED" was formed. Standardized is an LED insert for red, yellow and green signal heads. The working group consists of employees of the companies OSRAM, Garufo, IMS, Futurit and the companies organized in the ODG.

2003

Field tests (in particular integration tests) of the OCIT Outstations Version 1.1

2004

July 1, 2004 the interface OCIT-LED Version 1.0 will be released.

2004

July 15, 2004 the interface OCIT-O Version 1.1 is released

2005

The "OCIT-O Profile 2 - Transmission profile for dial-up connections in the fixed network and GSM mobile network" was approved as an OCIT standard.

2008

March 20, 2008 the OCIT-Outstations Version 2.0 for traffic signal controllers is released. OCIT-O Version 2.0 for traffic signal controllers is the further development of the existing OCIT-O version 1.1. The characteristic system functions are the standardized supply path and the standardized process data transfer.

2009

September 15, 2009 the OCIT-O profile 3 - transmission profile Ethernet with DHCP are released.

2010

September 1, 2010 The OCIT-C Version 1.0 new standard for communication between core components is released.

2011

April 11, 2011 the ODG-V2 Tracer is released. The ODG V2 Tracer is used to trace BTPPL telegrams based on OCIT-O V2.0 or OCIT-O V1.1. With the help of this software, the BTPPL communication between field device and central unit can be logged and analyzed.

2012

The OTEC was dissolved in March and the rights to OCIT-I transferred to the ODG.

2012

The "OCTS Harmonization Panel (Open Communication Standards for Traffic Systems / Open Communication Standards for Traffic Systems)" was established as a replacement for the round table. This body aims to promote interface development.

2013

Software maintenance of OCIT-I is discontinued. The contents of OCIT-I are incorporated in OCIT-C.

2013

February 6, 2013 the OCIT-O V2.0 Testsuite MAT is released. The "OCIT-O V2 Testsuite MAT" enables the construction of a test tool for the automatic testing of traffic signal controllers with the OCIT-O V2.0 interface. With the appropriate test tool can be assessed in a short time and without further user intervention, whether a minimum required functionality is present and functional (Minimal Acceptance Test).

2014

November 12, 2014 the new version OCIT-C 1.1 is released.

2015

March 05, 2015 the documentation for OCIT-C V1.1 is available in English

2016

02. April 2016 OCIT-O V3.0 and OCIT-O Car will be presented at Intertraffic Amsterdam. With OCIT-O V3.0 and the corresponding specifications in OCIT-C, the OCIT system integrates with the cooperative radio-based infrastructure in the automotive sector. This makes it possible in the OCIT system to integrate danger reporting, prioritization of public transport vehicles and special vehicles, forecast data, supply of topology information and quality assurance into traffic management.
