The demands on a driver to maintain a consistent path is reflected in the driver’s workload. Visual demand, which can be measured using vision occlusion, can be used to quantify driver workload. Vision occlusion blanks out the driver’s vision of the roadway using a visor or other similar device. By measuring the amount of time the driver is viewing the roadway, a measure of the information load...

The US Army Research Laboratory designed, developed and tested a novel switched beam radar system operating at 76 GHz for use in a large autonomous vehicle to detect and identify roadway obstructions including slowly-moving personnel. This paper discusses the performance requirements for the system to operate in an early collision avoidance mode to a range of 150 meters and at speeds of over 20...

Aiming at the surrounding rock failure of heterogeneous and unequal pressure circular roadways, approximate analytical algorithm plastic zone is proposed. Through comparison calculations numerical simulation, shape characteristics evolution law rock’s are studied, relative error two calculation methods analyzed. The results show following: (1) With an increase or decrease in lateral coefficient...

The paper contributes to the detection of driving on the wrong side of the road by addressing in particular multi-lane road situations. We suggest a solution using video data of a single camera only for identifying the current lane of the ego-vehicle. GPS data are used for knowing defined constraints on driving directions for the current road.

In order to overcome the support difficulty of serious floor heave caused by rock burst, with ventilation roadway in Hegang Xing An Coal Mine as engineering background, treatment scheme concrete-filled steel tube corner pile and grouting is put forward. Based on solution slip line field under plane strain condition, mechanical model slip-type established, formula for calculating critical failur...

In order to solve the problem of asymmetric large deformation high-stress soft rock crossing roadway under complex geological conditions in deep mines, taking 2# total return airway 76.2# section Wuyang Coal Mine as engineering background, causes and failure mines were summarized analyzed by means field investigation, theoretical analysis numerical simulation, high-efficiency support technology...
