Early detection of exit only and shared lanes using perception technology
First Claim
1. An in-vehicle system for identifying lane types on a roadway, the system comprising:
- one or more detectors that capture data regarding lane markings on the roadway;
a processor and a non-transitory data storage on which is stored computer code which, when executed on the processor, causes the in-vehicle system to;
categorize the lane markings;
identify an exit-only lane in response to detecting lane markings on a side of a vehicle characteristic of exit-only lanes; and
determine whether the identified exit-only lane is a presently occupied lane or a neighboring lane based on a side of the vehicle on which the characteristic lane markings are detected.

Abstract
An in-vehicle system for identifying exit-only lanes and shared exit lanes on a roadway having a first camera for obtaining image data regarding lane markings on the roadway, a second camera for obtaining image data regarding exit signs, a lane marking detection module for detecting lane markings on the roadway, an exit sign detection module for detecting exit signs, and an exit sign analyzer for detecting arrows on the detected exit signs. The in-vehicle system categorizes detected lane markings as one of standard frequency dashed lane markings, high frequency dashed lane markings, and solid lane markings, and identifies an exit-only lane and a shared exit lane in response to the categorizations of the detected lane markings and characteristics of the detected arrows.
