Urban arterial streets are characterized by intersections and efficient progression of platooned vehicles along signalized corridors in urban areas facilitates faster transportation systems in cities. Achieving this goal often relies on the platoon-based coordination of signalized corridors, which aims to facilitate the smooth movement of platooned vehicles through a signalized corridor by minimizing delay and maximizing traffic flow. However, urban road networks in developing countries like India face unique challenges. These challenges include a diverse mix of vehicles, lack of strict lane discipline, and the presence of various roadside frictions like bus stops, on-street parking, pedestrians, etc., which disrupt platoon movement and reduce road capacity. Unlike well-established platoon dispersion models developed for lane-disciplined homogeneous traffic, India’s road conditions are characterized by heterogeneity and lack of lane discipline. Hence, it is important to understand platoon dispersion on signalized corridors under the impact of roadside frictions. This study uses various speed variability measures such as speed profiles, standard deviation, relative standard deviation, and relative speed difference for assessing platoon dispersion patterns along the downstream of traffic signal for identifying areas of initial and higher platoon dispersion on signalized urban arterials under heterogeneous traffic conditions, under the influence of curb-side bus stop. Data were collected using videographic survey technique. Each platoon emerging from the signalized intersection during the green time was analyzed at every 30 m interval up to 420 m downstream of the traffic signal. The analysis revealed the locations where initial and higher platoon dispersion occurs at downstream of traffic signal based on the variations depicted by the measures that quantify speed variability. The results obtained were compared with those obtained in the previous studies, where platoon dispersion was analyzed without any effect of side frictions.

摘要

Urban arterial streets are characterized by intersections and efficient progression of platooned vehicles along signalized corridors in urban areas facilitates faster transportation systems in cities. Achieving this goal often relies on the platoon-based coordination of signalized corridors, which aims to facilitate the smooth movement of platooned vehicles through a signalized corridor by minimizing delay and maximizing traffic flow. However, urban road networks in developing countries like India face unique challenges. These challenges include a diverse mix of vehicles, lack of strict lane discipline, and the presence of various roadside frictions like bus stops, on-street parking, pedestrians, etc., which disrupt platoon movement and reduce road capacity. Unlike well-established platoon dispersion models developed for lane-disciplined homogeneous traffic, India’s road conditions are characterized by heterogeneity and lack of lane discipline. Hence, it is important to understand platoon dispersion on signalized corridors under the impact of roadside frictions. This study uses various speed variability measures such as speed profiles, standard deviation, relative standard deviation, and relative speed difference for assessing platoon dispersion patterns along the downstream of traffic signal for identifying areas of initial and higher platoon dispersion on signalized urban arterials under heterogeneous traffic conditions, under the influence of curb-side bus stop. Data were collected using videographic survey technique. Each platoon emerging from the signalized intersection during the green time was analyzed at every 30 m interval up to 420 m downstream of the traffic signal. The analysis revealed the locations where initial and higher platoon dispersion occurs at downstream of traffic signal based on the variations depicted by the measures that quantify speed variability. The results obtained were compared with those obtained in the previous studies, where platoon dispersion was analyzed without any effect of side frictions.
