USING REAL-TIME TRAFFIC INFORMATION IN THE NAVIGATION SYSTEM FOR DETERMINING VEHICLE ROUTE

摘要

entrThis study presents approaches for identifying a route and selecting alternative routes by changing the followed route in accordance with traffic density, which is a huge problem for especially big cities, and according to information on this density. Normally, navigation devices identify the route by selecting the shortest way from the departure point to the destination point in accordance with the spatial data they obtain from the satellite. Instant traffic information is not considered in this selection. The most important attribute of this study is that the most suitable route will be selected by including the instant traffic information received in certain intervals and it will have the flexibility to change this selected route due to traffic on that route. With a study to be carried out with Ba?arsoft that provides substantial GIS (Geographic Information System) data to many navigation companies, it is aimed that the most suitable route is identified with a simulation where both GPS (Global Positioning System) and instant traffic data will be used. Thus, the impact of instant traffic data on identification of the route will be analysed.Bu ?al??mada, ?zellikle büyük ?ehirler i?in büyük bir sorun olan trafik yo?unlu?unun ve bu yo?unluk bilgisinin gidilecek rotan?n belirlenmesi veya takip edilmekte olan rotan?n de?i?tirilerek alternatif güzergahlar?n se?ilmesine ili?kin yakla??mlar sunulmaktad?r. Normalde navigasyon cihazlar? güzergah?, uydudan ald?klar? konum bilgisine g?re harekete ba?lama noktas?ndan gidilecek hedef noktas?na en k?sa yolu se?erek belirlerler. Bu se?imde anl?k trafik bilgileri dikkate al?nmamaktad?r. Bu ?al??man?n en ?nemli ?zelli?i, belirli zaman aral?klar?nda gelen anl?k trafik bilgilerinin sisteme dahil edilerek en uygun rotan?n se?ilmesi ve se?ilen bu rotan?n rota üzerinde trafikten kaynaklanan sebeplerden dolay? de?i?tirilebilme esnekli?ine sahip olacak olmas?d?r. Bir?ok navigasyon ?irketine zengin GIS (Geographic Information System) verisi sunan Ba?arsoft ile yap?lacak bir ?al??ma ile hem GPS (Global Positioning System) hem de anl?k trafik verilerinin kullan?laca?? bir benzetim ile en uygun güzergah?n tespitinin yap?lmas? hedeflenmektedir. B?ylece anl?k trafik verilerinin güzergah?n belirlenmesine etkisi irdelenmi? olacakt?r.
