Efficent information provision in the event of delays 


You, of course, put together travel schedules and information booklets with the greatest of care. And you always strive for an optimum connection between the various journeys. But unexpected events can upset these schedules. An overhead wire struck by lightening or a bus caught up in a crash can easily cause delays and lead to grumbling passengers. What people find the most annoying about this is often not so much the delay itself but the fact that they do not know whether and when they can continue their journey. EDS T&T Solutions has developed various solutions that can help in these situations. Two examples are IVIS and RIVIS.


The information manager has an essential role in the information process relating to incidents. First of all, he (or she) keeps a constant lookout to see if, when and where incidents occur. With the help of IVIS and RIVIS he then collects all the relevant information on the incidents and organises it. Other staff within the organisation determine what has to be done to minimise the consequences of the incident. The information manager then collects and organises this information - again using IVIS and RIVIS - regarding the measures taken and the desired travel advice. The next step in the process is to inform the passengers and personnel. For this IVIS and RIVIS, respectively, can also be used. In this way the information manager is able to concentrate fully on his key task, which is to collect as much relevant information as possible.

Optimum information for passengers

With IVIS the transport company is able to inform passengers and other 'external' parties on the consequences of the incident. This is general information such as "There is no Intercity connection between Amsterdam and Abcoude. The railway company is deploying buses.'  This information can be sent via Teletext, SMS, WAP and e-mail. The system automatically generates the appropriate layout for the chosen medium.

The information manager enters all the information relating to the incident in the system. This is stored in a database, which also contains information on previous incidents, timetables and routes. Based on this, the system determines which parts of the journey are affected by the incident. As the system warns the information manager when certain messages have to be sent, no message will escape his attention. IVIS also ‘knows’ if information has already previously been given about the incident and therefore whether the message should be in the form of a 'follow-up' message. Using previously entered contracts and information profiles, IVIS also determines which information goes to which party.



And one's own personnel

RIVIS in theory does the same as IVIS, but is intended to keep your staff optimally informed. This leads to a number of important differences. RIVIS is, for example, region-oriented, knows the daily planning and so can calculate which trains are running in the region concerned between now and an hour's time. The program generates point-by-point technical information on individual trains in certain regions. These messages are put together automatically and cannot be modified. RIVIS sends fax messages, SMS messages and messages to maxers. RIVIS also communicates with a system that knows the GSM numbers of the various trains, so that messages can be sent to the personnel on the train as well.

Ease of navigation

Both IVIS and RIVIS use a tree structure (as used in Windows Explorer) in order to be able to navigate easily through the possibilities. With IVIS the information manager sees three different 'rooms'. In the 'Emergency Room' in addition to the tree structure he also sees whether and when a similar incident has occurred before as well as a summary of the entered information on the current incident. The 'Control Room' is for putting together messages based on all the collected information. Often the messages have already been generated by the system and so the information manager can go straight to the 'Post Room' to send the messages. RIVIS also makes use of rooms, but these are not seen by the users. They mainly make a distinction between minor train delays and serious disruptions.

A big advantage of using IVIS and RIVIS is therefore that the information manager can concentrate fully on his own task - collecting and organising relevant information. In addition, IVIS and RIVIS ensure that the messages to the passengers and staff are always correct, up-to-date and of the highest quality.
