Transportation systems are currently experiencing a fundamental transformation of their structures and organization, triggered by new technologies (self-driving cars, on-demand services, artificial intelligence) and the development of the sharing economy. In the past, travel choices usually restrict to private cars or public transportation. Now, we observe an abundance of travel options (biking, car-sharing, car-pooling, on-demand services, regular public transport). While promoting virtuous behaviors like ride-sharing, some options can also lead to increased distance-traveled because of improper management of idle vehicles or large fleet sizes. Competitions between mobility services may also harm the overall mobility and increase congestion, fuel consumption, and emissions. It is the case when ride-hailing services take users from public transportation because they offer more appealing travel options at the individual level. Finally, all mobility systems and services share the same and limited urban space, which give some leverage to local authorities to define how to shape multimodal transportation system and prioritize some mobility offers over other to reach collective goals.

The goal of this Ph.D. is to investigate how dynamic lane allocation policies can improve multimodal transportation network functioning and foster mobility options most in favor of collective optimum, i.e., reducing total travel times, fuel consumptions, and emissions. Several successful implementations of dynamic lane allocation have been developed for urban corridors, e.g., intermittent bus lanes (Chiabaut et al., 2012, 2014), or dynamic car-bus corridors (Anderson and Geroliminis, 2020) or pre-signal strategies (He et al, 2016). The idea is to allow a subset of vehicles in the dedicated bus lanes when no buses are circulating or by keeping the interactions at a minimum. Permanent lane allocation strategies are also used to favor some transportation modes, like bikes or taxis in dedicated bus lanes or high-occupancy lanes. In the future, a larger share of urban space might be dynamically segregated for travelers willing to use specific modes of transport. However, the situation is challenging in practice, when the road infrastructure capacity cannot be easily divided or when critical events may change the transportation priorities, infrastructure accessibility, or demand allocation. Some streets could be reserved, but significant effort is needed to (i) define which users have accessed to specific capacity batches to guaranty an optimal usage of the network, from a collective point of view and (ii) create connected subnetworks of dedicated roads that provides access to crucial parts of the city. It should be mentioned that dynamic lane allocation strategies can be framed in different ways like fully time-based, i.e., the capacity is allocated to only one class of vehicles at a time, or hybrid, i.e., both space and mode allowance can change with time. The connections between lane allocation and intersection control schemes should be investigated to guarantee smooth crossing for prioritized users. Actual traffic signals can commonly provide priority to transit vehicles on the main corridor but the problem becomes much more complex if they have to arbitrate between multiple users with different priority levels coming from multiple directions.

During this Ph.D., we will address the large-scale implementation of dynamic lane allocation policy considering daily demand profiles and different modes of transportation (cars, public transit, e-hailing services, and bikes). The robustness of the design will be tested considering different daily profiles mimicking the annual variations of urban loading patterns. To perform the simulations, we will resort to a new agent-based simulation framework developed in both ERC MAGnUM and METAFEW (Lamotte and Geroliminis, 2018; Mariotte and Leclercq, 2019; Paipuri and Leclercq., 2020). It permits us to consider all trips individually, whatever the transportation mode is while providing fast calculation, which is paramount for assessing the results of different lane allocation strategies and optimizing their parameters. This framework will be extended to better represent the local congestion dynamics related to the considered actual lane allocation schemes. About test cases, we can resort to realistic simulation environment (realistic demand profiles and network settings) implemented by the LICIT laboratory for the city of Lyon. Particular attention will be paid to designs fostering cooperation between complementary modes like on-demand or ride-sharing services and public transportation. For example, dynamic lane allocation could improve the accessibility of major public transportation hubs by on-demand services while not providing a competitive advantage in urban regions where public transportation is well-developed.
