Designing the new network and its capacity
Sub project C
Description
Removing 50% of the motor-vehicle lane miles requires to convert many roads into one-way streets for motor vehicles, to add dead end roads for motor vehicles, to find design solutions for service and emergency vehicles and to rethink junction design with busses and cycles in mind. It also requires a network, which accommodates the much larger flow of cycles and the possibility of cycle congestion.
The project will develop algorithms for the optimal design of the one-way-street networks for motorized vehicles. The algorithm will be enriched to allow for the overlay of the cycle and vehicle network and the adaptive change for emergency and service vehicles. The objective will be formulated as either multi-modal capacity optimization or as travel distance minimization to keep the environmental impacts under control.
The reallocation of the space allows us to rethink the urban space for all of its users, including cyclists, pedestrians and delivery/emergency vehicles. Respecting, but also rethinking the safety concerns of the existing design standards, this step will develop standards for the most important types of roads and junctions. It will verify that these types are compatible with the network design developed earlier and if necessary reoptimize the network.
Using MATSim, Sumo or an MFD-based simulation, the network will be assessed using an initial cost-benefit analysis using stylized results for the expected modal change. It will calculate the changes in travel time and in the required environmental indicators to provide an initial assessment of the new network and its design. The current Swiss norms will be employed to calculate all the relevant environmental impacts, e.g. CO2, NOx, small particles, noise, etc.
