VIRTUAL DRIP
Description
In the Netherlands, the term Dynamic Route Information Panel (DRIP) is used for an electronic route information panel. DRIP's are an example of a so-called soft traffic control measure, that is response to the measure is voluntary, not compulsory. Changes in route choice due to the DRIP are believed to be moderate. They are one specific type of electronic sign within the larger group of Variable Message Signs (VMS).
Objectives
The objective of the Virtual DRIP is to provide route information for the road user. In general, SPITS OBU displays information about the length of the queues on different alternative roads, so that the road user can optimize the route.
Inputs
-
SPITS OBU
-
Navigation system with HMI

Mobile communication technology for long range communications
Benefits
-
Communication of the up-to-date travel times for different routes
-
Provides information about the traffic distribution on a defined route along the main road network and on two alternative routes to a specific destination
-
Also provides information about (Obstruction information)road blocks and about (Incident information)localized incidents such as crashes, road works, open bridges, etc.

Project Outcomes
The product with a working HMI and model has been demonstrated for use on the A270 SPITS test location.
-
In practice there often are a few minutes between receiving the data and the (new) text being displayed on the DRIP while travelling
