Accident Diagnosis and Evaluation System in Parking Lots Using Multisource Data Based on Bayesian Networks

Table 8

Library of focused attention on controllable variables and corresponding measures.

Variable classification	Variable	Focused attention	Countermeasure
Environment (natural)	Time	High-risk period warning sign	Equip electronic flashing warning signs that can automatically identify high-risk periods and flash to remind drivers to drive carefully
	Light condition	Illumination system	Intelligent adaptive lighting system; induction lighting system installed on the roads around the parking lot; complete emergency lighting system
	Weather condition	Real-time monitoring of hazardous weather	Dynamic collection of dynamic weather changes; timely flashing of active warning signals in adverse weather conditions; adaptive fog light system and ground moisture warning signs
	Day of week	Peak time management	Real-time monitoring of parking lot activity, automatic identification of peak hours, strengthening equipment monitoring; safety management during peak hours
People	Total number of people involved	Crowd management	Combine facial recognition and crowd counting for crowd management; focus on the number of people in the car; control the number of vehicles entering the parking lot at one time during high-risk hours
Vehicle	Maximum speed limit	Speed limit regulation setting	Automatic speed measurements; periodic check speed limit settings; set dynamic speed limit policies if necessary
	Vehicle movement	Vehicle route guidance	Installation of dynamic guidance algorithms to avoid potential vehicle congestion and collisions; equip automatic guidance systems for dynamic traffic flow and indications of safe uncongested roadways; installation of permanent warning signs for lane changes and entry with night-time reflective material
	Vehicle speed	Speed monitoring and warning	Real-time speed detection; dynamic information alert and overspeed warning; corresponding penalty measures
	Vehicle use and type	Vehicle type identification	Automatic identification of vehicle types and sizes at the entrance; separate parking for different vehicle types; exclusive management of high-risk vehicles
