Modelling the net traffic congestion impact of bus operations in Melbourne

Public Traffic Congestion Estimation Using an Artificial Neural Network

“…In terms of evaluating the impact of bus priority lane on traffic congestion, several research projects have been undertaken. Agrawal et al [9] examined different strategies that were applied to manage shared-use bus priority lanes in the major congested urban centers of seven cities throughout the world. Based on the application of bi-level programming on bus lane planning and optimization, Yu et al [32] proposed a bi-level model that performed well with regard to the objective of balancing the transport service level among all the bus lines.…”

“…these network optimization models developed in the above-mentioned articles had been usually applied in uncongested road segments.Public traffic condition refers to the traffic volume of the road network and its dynamic spatial-temporal distribution, which can reflect the degree of congestion [8]. Recently, the traffic congestion impacts of bus operations on a road segment or a corridor have been investigated by researchers [9,10]. These congestion effects mainly include the effects of bus stop design, bus travel time, and bus priority options such as exclusive bus lanes or priority signals for buses [9].…”

Understanding these congestion impacts can help operators to identify the effectiveness of transport network optimization in relieving congested areas or congested routes.…”

Development of models for assessing a driver's failure­free operation in a transportation system under conditions of traffic congestion

“…Authors of paper [17] conducted studies related to the formation of traffic jams due to redistribution of passenger traffic from passenger cars to buses and vice versa. On the one hand, they carried out an initial survey to determine the transition from a bus to a car when buses were unavailable.…”

“…The final values of the ratios in a traffic jam will be values of the levels of the driver's failure-free operation on a section of a network immediately after a traffic jam. We calculated the corresponding ratios of probabilities for drivers of twenty and sixty years at different durations of traffic jams for six options of traffic jams (3 to 18 minutes at 3-minute intervals) and different initial values of fatigue before traffic jams for the assessment using model (17).
