Table I: Strengths and Weakness Comparison of Detector Types[6] Type of the Detector Detector Methods Comparison Working Mechanism Strengths Weaknesses Inductive loop Detects thevehicle by sensing theloop • Flexible design to fulfill a great variety of applications. • Unresponsive to bad weather. • Offers accuratecount data. • Traffic disruptions while installation andmaintenance • Prone to damage by heavy vehicular movements and duringroad repairs h Microwave radar Transmitssignals in the recognitionregions and captures the echoed signalsfrom vehicles • Unresponsive to bad weather. • Speed is measureddirectly. • Multiple laneoperation. • Continuous-wave Doppler sensors are incapable of sensing immobile vehicles. Acoustic Detect audiblesounds produced by vehicular traffic. Using them vehicle presence and speed are measured. • Unresponsive to precipitation. • Multiple laneoperation. • Vehicle count accuracy may be affected by cold temperature. Magnetic Detects the presence of a vehicle by measuring the perturbation inthe Earth's magnetic field • Applicable where loops are not likely. • Insensitive to badweather. • Installation of some models does not require a pavement cut. • Less prone than inductive loops to pressures of vehicles. • Installation needs a boring under the road. • Incapable of sensing immobile vehicles. Ultrasonic Transmits ultrasonic waves and again collect the echoed waves from an object. • Monitors multiplelanes. • Proficient in detecting over - height vehicles. • Performance is affected by environmental circumstances. • Occupancy measurement on freeways may be degraded with large pulse repetition periods. VIP (Video image processor) This system normally consists of a camera, processor, andsoftware. • Monitors multiplelanes. • Simple to add and change detection areas. • Offers broad-areadetection. • Installation and maintenance require lane closure. • Performance is sensitive to bad weather, vehicle shadows, and dust onthe camera lens. Type of the Detector Detector Methods Comparison Working Mechanism Strengths Weaknesses • Requires specific camera mounting height for finest vehicle presence detection and speedmeasurement. Light Detection and Ranging (LIDAR) This is a remote sensing method that uses a pulsed laser to measure ranges of variable distances. • Monitors multiple lanes. • Simple to add and change detection areas. • Insensitive to bad weather. • Offers broad-area detection. • Traffic disruptions while installation andmaintenance. © 2023 Global Journals Global Journal of Computer Science and Technology Volume XXIII Issue II Version I 41 ( )D Year 2023 Traffic Flow Forecast based on Vehicle Count
