Dispensing system for marking a transportation corridor

A system for dispensing a fast curing epoxy traffic marking composition to a transportation corridor includes a plurality of bins positioned on a transportation corridor marking dispensing apparatus. A first bin contains an epoxy coating which is applied by the dispensing apparatus on a transportation corridor. A second bin contains at least one curing agent which is coated on a carrier such as glass beads or porous silica. These carriers are dropped onto the epoxy coating by the dispensing apparatus and promote rapid curing of the top layer of the epoxy coating while the bottom layer is given additional time to adhere to the roadway surface. This enables the application contractor to open a marked roadway in a quicker manner with less motorist disruption. An optional third bin contains retroreflective beads which are applied to the epoxy coating by the dispenser apparatus to improve visibility of the line marking.

An autonomous vehicle (AV) can process a live sensor view to autonomously operate acceleration, braking, and steering systems of the AV along a given route. While traveling along the given route, the AV can identify an encoded road stripe in the live sensor view, and decode the encoded road stripe to determine location data corresponding to the encoded road stripe.

Road Marking Scan and Transfer System
20170191233 · 2017-07-06 · ·

A system for applying roadway markings to roadways, including at least one imager for acquiring image data of original roadway markings on an original roadway surface. A first vehicle marking controller receives and stores the image data in combination with acquired location data associated with the original roadway markings. One or more milling tools mill the original roadway surface and create a milled surface. The one or more milling tools are positioned behind the at least one imager relative to a direction of travel. A first vehicle marking module is responsive to the first vehicle marking controller for applying roadway markings based on the location data of the original roadway markings and the image data, the first vehicle marking module positioned behind the one or more milling tools relative to a direction of travel.

ROAD SURFACE MARKING DETERIORATION ANALYSIS APPARATUS, METHOD, AND COMPUTER-READABLE MEDIUM

A road surface marking detection means detects a road surface marking on a road, based on sensor information acquired by sensing a road. An interruption detection means detects a portion where the road surface marking is interrupted, based on a detection result of the road surface marking. A factor determination unit determines a factor for which the road surface marking is interrupted with respect to a portion where a matter that the road surface marking is interrupted is detected.
