PROPOSAL DEFENCEAUTOMATIC ACCIDENT LOCATION DETECTION SYSTEM

1OVERVIEW2INTRODUCTIONAutomatic Accident Location Detection System - with an automatic notification to the emergency service with the accident locationThe system is being separated into two parts: vehicle accident detector and website location system. Finding the suitable algorithm for the shortest path and enhancement to the website location system

3PROBLEM STATEMENTIt takes time for the authorities to reach where the accident has taken place.

No such system for locating or identifying where and when accident is taking place and responding to the emergency medical team. 4RESEARCH QUESTIONSWhat is the current method of locating road accidents?How long has the accident happened?How is it possible to report the situation when an accident has happened?What is the best algorithm in finding the shortest and nearest path between hospital and accidental scene?

5OBJECTIVETo study for finding the shortest path and route the ambulance to scene.To create a web based system where reported information can be accessed and displaying the exact location of the accident on the map.To test the system for performance and efficiency.

6LITERATURE REVIEWEarths True ShapeAccording to (Cook, 2009), the Earths polar diameter is about 43 kilometres shorter than its equatorial diameter, a difference of about 0.3% and this is due to the equatorial bulge caused by the Earths rotation.7LITERATURE REVIEWThe Great Circle or orthodromic distance is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere. According to (Admiralty, 1967), the great circle is important in navigation because it gives the shortest distance between two points along the surface of a sphere. D = 1.852 * 60 * ARCOS ( SIN(L1) * SIN(L2) + COS(L1) * COS(L2) * COS(DG))8LITERATURE REVIEWVincentys formula is developed by Thaddeus Vincenty in 1975 which are to calculate the distance between two points in the surface of a spheroid.

9LITERATURE REVIEWDue to the high floating point precision needed in the previous algorithm, Haversine formula is recommended as it does not generate serious rounding errors for distance larger than a few meters (Goh, 2013). 6371*2*Atan2(sqrt(1-(SIN((lat2-lat1)/2)^2+COS(lat1)*COS(lat2)*SIN((lon2-lon1)/2)^2)),sqrt(SIN((lat2-lat1)/2)^2+COS(lat1)*COS(lat2)*SIN((lon2-lon1)/2)^2))

10LITERATURE REVIEWModified Harversine Formula was proposed by Eddy Goh as alternative formula to calculate the distance between two points. According to (Goh, 2013), the formula recorded an increase of speed of the execution by 99% and result in 0.0458 seconds of average speed with same accuracy as the original Haversine Formula.D = 6371 * ACOS(COS(LAT1)*COS(LAT2)*COS(LON2-LON1)+SIN(LAT1)*SIN(LAT2))

11RESEARCH METHODOLOGY12PLANNINGRequirement Gathering Gathering information on tools required, software needed, hardwares and etc.

Feasibility Study :- Technical feasibility: Not a very complex system which requires very high technical skills to accomplish- Economical feasibility: If system is customized, would be expensive. However in long run, it will be beneficial.- Organizational feasibility : Majority of hospitals are showing high interest in purchasing the system.13DATA GATHERING & ANALYSISResearch - Research on other identical projects and algorithmsQualitative Interview Technique Finding out the existing methods used.Algorithm Comparison comparison of all the researched algorithm in choosing the suitable algorithm for finding the shortest distance
