“…This can be seen as a disadvantage because complex methods are required to resemble prevailing conditions. This issue was pointed out by Selekwa et al [19] and Penabaena-Niebles et al [15] which stated that existing methods usually are not based on any optimization procedure and measurements of traffic flow are not optimized. As a result, the need of a more complex mathematical method able to resemble in a more accurate way the existing conditions arises.…”

“…Two approaches have been identified in the literature to address the transition phase: applied methods, which are studies where the transition is attained by a sudden or gradual change of the parameters of the plan, while mathematical methods are based on optimizing operational measures of effectiveness during transition using mathematical models [15,16]. A recent study [15] concluded that most transition articles are focused on applied methods (78.3%) and only a few addressed mathematical methods (21.7%).…”

Signal plan transition is the process of changing from one timing plan to another. It begins when the first intersection starts adjusting signal timing plans and ends when the last intersection completes adjusting signal timing plans. The transition between signal timing plans is required because traffic patterns change during the day. Therefore, it is necessary to modify signal timing parameters offset, phase split, and cycle length for different expectations of traffic volume. This paper presents an alternative and new mathematical model to enhance the performance of traffic signals coordination at intersections during the transition phase. This model is oriented to describe the transition regarding coordination parameters in all intersections of an arterial road for minimizing the social cost during the transition phase expressed in function of costs due to delays, fuel consumption, and air emissions. An ant colony algorithm was designed, coded, and simulated to find the optimal transition parameters using available data. The model was evaluated based on its ability to minimize social costs during the transition period. Results showed that the proposed method performs better than traditional ones.

“…Most studies performed to date on traffic signal transition strategies have been focused on comparing actual transition methods using different scenarios in order to evaluate their potential impact and performance measures on the operation of traffic signals and traffic congestion. In general, most of the transition research articles are focused on applied methods (78.3%), and only a few addressed mathematical methods (21.7%) [14]. Table 1 lists the articles found in the literature that aim to optimise an operational measure of effectiveness in a mathematical model.…”

“…A large amount of funding and effort for collecting traffic count data may be the primary reason that hinders the theoretical methods from being implemented in the field. Regardless of the complexity of a transition method, there is a potential for plan transition to lead to serious disruptions of traffic flow and long-lasting effects [4,11].…”

Four fundamental insights into transition methods are provided from the perspective of traffic engineers. An improved empirical transition method (i.e., Shortest-way) is developed with the goal of reducing the time spent on offset correction and the offset deviations of the coordinated phases during the transition period. Shortest-way operates stepwise and can be activated to correct offset at the scheduled time to switch plans. The maximum amount of adjustment that can be made to a transition cycle length is calculated based on the timing parameters of active phases in the old and new plans. The problem of cycle length distribution is formulated as a nonlinear integer programming problem, aiming at minimizing the sum of the squares of the intersection offset deviations of all the transition cycles. The portion of the cycle length that can be allocated to each phase in a transition cycle is calculated based on its splits in the old and new plans and its potential contribution to the maximum amount of adjustment to the cycle length. The numerical experimental results proved the potential advantage of Shortest-way over CORSIM Shortway and justified the necessity for managing the time to switch plans at the intersection level.
