ALMAGuide LLC has received approval for patents that describe technology that takes information from centralized traffic management control centers, conditions the data, and uses proprietary algorithms and propriety data structures to tell the vehicle (either with driver or driverless) the best lane to be in on the highway, based on traffic flow several miles ahead of the vehicle, and the most appropriate speed for the vehicle. ALMA also applies and adapts the lane guidance technology for trucks.
ALMA (Advanced Lane Management Assist) technology is an improvement over what drivers currently do, or what driverless cars are moving towards in the near future, because lane changes performed without using advanced lane management techniques being based on the immediate environment as compared with the prospective environment over which they soon will be traveling.
As a result, many lane changes on highways are unnecessary; they are done under the misconception that the other lane is moving faster. Studies have shown that this is often not the case, which the driver learns after the unnecessary lane change is made. Unnecessary lane changes result in additional accidents (about 4% of crashes result from lane changes) and needless driver stress. Unless driverless technologies are coupled with strategic lane choices based on what is happening in each lane several miles ahead of the vehicle on the highway they do not change the sub-optimal decision-making framework for making lane changes.
ALMA Management Center (ALMAMC)
The ALMAMC obtains lane based traffic data from traffic management centers (TMCs) or other sources, conditions it and develops parameters and other information in a reference frame that is specifically formulated to address lane selection requirements. This information will be used by the vehicle application software.
Guidance Assist Vehicle Module (GAVM)
Using ALMAMC data, the GAVM accepts information from the vehicle operator expressing his driving preferences and other information. It also accepts information from the vehicle (position, speed, and destination). It provides lane choice and target speed recommendations using cellular based technology or other communication techniques.
ALMA Truck Vehicle Module (ALMATR)
Trucks require a different set of algorithms for optimal lane choice and target speed selection. Lane changes for trucks on freeways should be limited to situations that can provide a minimum threshold of time savings. Using this information as well as information supplied by the truck and truck operator, ALMATR provides the recommended lane and target speed for the truck.
