“…Nesheli and Ceder (2014) enhanced the simulation model by introducing the concept of skip-a-segment in addition to skip-a-stop. Recently, Sun and Schonfeld (2016) proposed a vehicle holding method for intermodal freight operations by considering decision risks and correlations among vehicle arrivals.…”

We propose a robust schedule coordination scheme which combines timetable planning with a semiflexible departure delayed control strategy in case of disruptions. The flexibility is provided by allowing holding for the late incoming bus within a safety control margin (SCM). In this way, the stochastic travel time is addressed by the integration of real-time control and slacks at the planning phase. The schedule coordination problem then jointly optimises the planning headways and slack times in the timetable subject to SCM. Analytical formulations of costs functions are derived for three types of operating modes: uncoordinated operation, departure punctual control and departure delayed control. The problem is formulated as a stochastic mixed integer programming model and solved by a branch-and-bound algorithm. Numerical results provide an insight into the interaction between SCM and slack times, and demonstrate that the proposed model leads to cost saving and higher efficiency when SCM is considered. Compared to the conventional operating modes, the proposed method also presents advantages in transfer reliability and robustness to delay and demand variation.

“…Making obligation is necessary when a vehicle is ready and when a new vehicle arrival forecast is available. Figure 3 shows a simplified case where two incoming trucks arrive at the specified transfer terminal and depending on the arrival time of the vehicle, need to determine the start or hold of the outbound train [14].…”

For the sustainability of future logistics systems, Physical Internet is one of the most determined idea. Initial solutions and ideas exist, but the development in this area is far from complete. In our opinion, vehicle technology trends such as interconnected, autonomous vehicles and the platooning system are an important opportunity for the development of logistics network. This research aims to investigate how these new types of processes can be modelled using the results of a freight holding problem. The article surveys the possibility of reconfiguration of the platoons in the Physical Internet system by creating a virtual transfer point.

“…To handle with this intractable issue, researchers have proposed many control methods. With the advent of new technologies, some holding strategies have been proposed to take advantage of real-time information so as to reduce passengers' waiting times [3][4][5][6]. Using real-time information, many headway-based holding strategies have been proposed to adaptively control the system [7][8][9][10][11][12][13].…”

The headway-based control method is usually used to regulate the bus headways to improve the bus operation. However, these control methods only focus on equalizing bus headways, neglecting analysis for STD (standard deviation) of passengers on the buses. Therefore, in order to fix this gap, this paper analyzed performance of the control method in terms of regulating bus headways and number of passengers on the buses under variable number of buses on the route. First, as an enhanced version of headways-based control method, a coordinated control method based on the self-equalizing bus headways concept involving bus holding and stop-skipping is proposed. A discrete system is formulated to describe the bus operation, and the coordinated control method is imbedded into it. In order to reflect the performance in regulating bus headways and the number of passengers, two indexes are formulated, respectively. Finally, a set of numerical analysis was conducted. The test results showed that the regulated bus headways can make the number of passengers on buses equalized. As a by-product, the headway-based control method can make the bus capacity be well utilized by equalizing bus headways on the bus route.
