Trafik Yönetiminde Şerit Kontrol Sistemlerinin Etkinliğinin İncelenmesi

Öz

Trafik kaza-olayları otoyollardaki trafik sıkışıklığının önemli nedenlerindendir ve esnek trafik kontrol yöntemleri gerektirmektedir. Şerit kontrol sistemleri (ŞKS), otoyollardaki şerit kullanımını yönetmek için kullanılan trafik yönetim teknolojisidir. Bu teknolojide, her şerit üzerinde şerite özel bir elektronik tanıtı ile sürücülere Değişken Hız Sınırı (DHS) veya şerit kapatılması bilgisi iletilerek trafik yönetimi yapılmaktadır. Bu çalışmada, D100 Karayolu´nda bulunan bir yol ağında tek bir şeridin kaza sonucu kapanması durumunda, 141 senaryoda, farklı uyum, talep ve konumlarda ayrı ayrı ve birlikte ŞKS ve DHS uygulamalarının mikroskobik olarak etkinliği ölçülmüştür. ŞKS´nin tek başına uygulandığı en iyi senaryoda ortalama seyahat süresi %16.76 azalırken, ortalama seyahat hızı %20.19 artmıştır.

The Investigation of The Effect of Lane Control Systems on Traffic Management

Öz

Traffic incidents are one of the major causes of traffic congestion requiring flexible traffic control methods. Lane control sistems (LCSs) are a form of traffic management technology for managing lane use on freeways. This is accomplished by posting speed limits or notices to vacate/change a lane on an electronic sign above each lane. In this study, the effectiveness of LCS and speed limit implementations is tested using 141 scenarios including different compliance rates, traffic demands and LCS locations in a single-blocked-lane incident case on a microsimulation model of a network in D100 Highway in Istanbul. The best scenario (LCS implementation only) decreased the average travel time by 16.76%, and increased the average speed by 20.19%.
