Adaptation d’un système de préfeu dans le but de pérenniser les pistes cyclables temporaires. Comment pérenniser la mise en place des pistes cyclables temporaires tout en maintenant un réseau efficace et une congestion acceptable et contrôlée ?

Abstract : This study deals with the possibility to make a success of temporary cycle lanes which have been implemented during the lockdown due to Covid-19. The durability of this kind of infrastructure raises two main problems, the improvement of cycling conditions and the quality of the network for cars. This work studies the optimum of giving place to bicycles and keeping a hight level of quality for cars. First, the implement of the temporary lanes is described. Authorities have been pushed to implement this cycle urban planning. These causes are explained. However, this work shows the drawbacks of this kind of urban planning. There is a diminution of capacity on intersections and it drives to a reduction of the network quality for cars. It could increase the risk of the congestion. What is more, the network quality depends on the management of intersections. Then, the system of pre-signal, already used for improving the traffic conditions for buses is described. An adaptation of this system is realised to the bicycle traffic. This adaptation appears like an alternative to the temporary cycle lanes. It can be a solution to better share the space between bikes and cars. This idea is part of the concept of tactical urban planning which aims the good conditions of lives and a durable city. After, the performance of the three models are tested. In order to help to quantify the performance of the different models, tools are introduced. The total delay and the level of congestions are these tools which help to understand what is going on, during simulations. Car demand are introduced in these three models. The study of the pre-signal parameters drives to the creation of a tool which links car demand, ratio of the pre-signal and the distance between the pre-signal and the traffic signal of the intersection. Several ways to use this tool are given. It could be a good help to foresee the evolution of congestion or to dynamically manage the intersection. Results show that the pre-signal could be a solution in several cases, it improves the bike security for a minimal delay for cars, compared to the temporary cycle lanes. The limits and the ideas to continue this work are presented.
