“…On the other hand, optimising at the same time the size of the vehicles used along with their routes and schedules increases the complexity of the optimisation problem, and suitable solution techniques are needed in order to produce good‐quality solutions in a reasonable time, as pointed out by Wang et al.

The growing number and complexity of modern megalopolises, where several millions of inhabitants request efficient transport services, pose colossal challenges to urban mobility. To capture the ever‐increasing demand for mobility without further deteriorating the traffic congestion, it is essential that the resources available are used as efficiently as possible. Besides, the traditional means of transport (train, metro, bus, taxi), each responds to a particular segment of the global demand for mobility. Nowadays, transport planners can take advantage of the progress in information technologies and optimisation methods to design modern services that integrate and coordinate different means of transport. These services are potentially capable of capturing additional segments of mobility demand and, as an outcome, reduce the usage of private vehicles. Building upon these general ideas, a growing number of researchers have studied various forms of transport flexibility as well as the integration among different means of transport. This survey provides an overview of the trends emerging from contributions from the operational research literature on urban passenger transportation. We have analysed the literature according to the dimensions of flexibility and integration of the transport service studied. For each of the application areas identified, we convey the main trends studied, summarise the most relevant solution approaches and outline some open research directions that deserve particular attention.

“…Chandra and Quadrifoglio [28] extended this model [18], using a gravity-based accessibility model to evaluate the accessibility impacts for first-/last-mile transport connectivity in the case of fixed-route transit and DRT, although using the same uniform demand across space. Other issues investigated through analytical models were fleet sizing based on a given quality of service for users [10], route design [20,29], and the choice between different flexible transit strategies to accommodate a variable demand level [30], or estimating how user and operator costs vary according to the demand density, the service area [31], and the fleet size [32].…”

Feeder transport services are fundamental as first and last-mile connectors of mass rapid transit (MRT). They are especially beneficial in low-demand areas where private transport is usually the main transport mode. Besides, the rapid spread of new technologies such as vehicle automation and the shared mobility paradigm gave rise to new mobility-on-demand modes that can dynamically match demand with service supply. In this context, the new generation of real-time demand-responsive transport services can act as on-demand feeders of MRT, but their performance needs to be compared with conventional fixed-route fixed-schedule feeders. This article aims at presenting an agent-based model able to simulate different feeder services and explore the conditions that make a demand-responsive feeder (DRF) service more or less attractive than a fixed-route fixed-schedule feeder (FRF). The parametric simulation environment creates realistic constraints and parameters that are usually not included in analytical models because of high computational complexity. First, we identified the critical demand density representing a switching point between the two services. Once the demand density is fixed, exploratory scenarios are tested by changing the demand spatial distribution and patterns, service area, and service configurations. Main results suggest that the DRF is to be preferred when the demand is spatially concentrated close to the MRT station (e.g., in a TOD-like land-use area) or when station spacing is quite high (e.g., a regional railway service), whereas the FRF performs better when the demand is mainly originated at the MRT station to any other destinations in the service area (e.g., during peak hours). Besides, automated vehicles could play a role in reducing the operator cost if the service is performed with many small vehicles rather than higher-capacity vehicles, even if this would not imply a major benefit gain for the users.

“…Pan et al [4] optimized irregular service areas and optimal routes with the objectives of maximizing the number of passengers served and minimizing operating costs. Wang et al [3] designed a highdegree-of-freedom responsive transit system and proposed an optimization method for vehicle routing, scheduling and service area. ey also constructed the model by considering factors such as vehicle capacity constraints.…”

The flexible-route bus system is a type of dynamic public transit service. Routes and timetables are not fixed during the operation process, and driving routes are planned according to passengers’ reservation needs. This study develops a model that considers inter-regional travel demands. The optimal network layout is determined by minimizing an objective function that comprises operator and user costs. Then, two cases with and without loop-line buses are analyzed. In the case of the joint optimal solution, the parameter values of region side width, region angle, and cost components are compared. Results indicate that regional flexible transit is suitable for operation in areas with low demand density. Within certain ranges, increases in vehicle capacity and in the number of circle layers result in additional average total costs. Furthermore, adopting a mode with a loop is better when numerous inter-regional demands exist. The findings derived from numerical and sensitivity analyses can be used as planning guides for designing flexible-route bus systems.
