Method of monitoring vehicular traffic and of providing information to drivers and system for carring out the method
TLDR
In this article, road and traffic conditions are detected with roadside traffic sensing equipment, and the conditions are displayed over luminescent elements with signal lamps distributed at intervals along the road and combined into chains of lamps.Abstract:
An arrangement for monitoring vehicular traffic and providing information and warnings to drivers of traffic disruptions, driver error, dangerous road conditions, and severe weather. Road and traffic conditions are detected with roadside traffic sensing equipment, and the conditions are displayed over luminescent elements with signal lamps distributed at intervals along the road and combined into chains of lamps. The luminescent elements are illuminated simultaneously or in sequence for providing continuous traffic information. A processor network and a signal network are combined through a communication network to regulate the luminescent elements by processing, if necessary, under real time controlled conditions.read more

Method for traffic determination in a routing and information system for individual motor vehicle traffic
TL;DR: In this article, a routing and information system for individual motor vehicle traffic is used, in which by way of stationary routing station poles, route information and local information are transmitted to the passing vehicles.
Patent
Vehicle pacer system and a method of spacing moving vehicles along a traffic lane of a roadway
TL;DR: In this paper, a series of means are disposed along the traffic lane to display a pacing signal, and each means is adapted to selectively display a signal or indicator which is timed with respect to the other means so as to provide a "''continuous signal'' corresponding to a vehicular speed of, for example, 60 miles per hour along the lane.
