Transit Signal Priority for an Integrated Traffic Signal System

“…Therefore, the various arrival instants of two-way buses at stops must be considered to increase the TSP effect while applying the TSP to near-side stops. Considering this situation, a previous study designed a TSP model using number 1 and number 2 [23]. However, STEP BAND [23] used an average value for the passenger boarding and alighting time, which is actually variable over time because of variations in passenger demand.…”

“…Considering this situation, a previous study designed a TSP model using number 1 and number 2 [23]. However, STEP BAND [23] used an average value for the passenger boarding and alighting time, which is actually variable over time because of variations in passenger demand. By contrast, this study uses a normally distributed stochastic passenger boarding and alighting time to consider this variability.…”

“…In typical studies, a passive TSP is applied to an artery, and a model is developed to ensure the progression of both general and transit vehicles on the main road [17,20,23]. However, side-street users have rarely been considered; one exception is the work of Jeong and Kim [16], who maintained the existing cycle length and green split to satisfy the desired green times of other road users.…”

“…STEP BAND. STEP BAND maximizes the two-way bandwidth in units of stops based on MAXBAND LP2 [23]. The subsystem can be divided into stops, considering the bus halts at the stop.…”

“…To enhance the passive control strategy under dwell-time uncertainty, Kim et al [22] developed bus-based signal coordination, which account for the average dwell time and its variance on arterial roads with heavy bus volumes. Han et al [23] designed STEP BAND, a progression-control-based TSP that follows a uniform arrival distribution. STEP BAND supports nonstop bus movement and reduces delays for general vehicles driving on the main road.…”
