Variable Message Signs allow drivers to be alerted about special events happening on the road. For example, there could be traffic congestion or an accident for example. This prepares the driver to take a quick and sensible decision. Another use of variable message sign is to inform drivers about parking and guide the drivers efficiently towards available parking space.
ITS in general has taken the lead in improving numerous frameworks such as for example SCATS, Variable Message Signs, climate stations and various other sensors and information systems.
With the increase in data generation through connected sensors and controllers, there is a need to standardize the data exchange protocols.
Specialists are urging the industry and authorities to agree on open frameworks to improve interoperability and data sharing.
