Abstract
Urban mobility is a key aspect of sustainable transportation, with growing attention to integrating local public transport with shared mobility options such as bikes, scooters, mopeds and cars. This integration can significantly improve first-mile and last-mile connectivity, making urban mobility more efficient. A crucial element in this integration is the development of mobility hubs, physical locations designed to facilitate seamless connections between different transportation modes. While shared mobility and mobility hubs are now studied from different points of view at the international level, research on this topic in the Italian context remains limited.
To address this gap, we are conducting a survey on mobility habits and patterns in 12 major Italian cities. This study will analyse urban commuting behaviour and assess interest in mobility hubs, including their optimal design. Our questionnaire examines key factors influencing the projected use of mobility hubs, including individual socio-demographics, travel preferences, and attitudes toward public transport and micromobility. By applying discrete choice modelling techniques, we aim to understand the relationship between public transportation and shared micromobility within an integrated multimodal network.
This research is the first in Italy to systematically explore the intersection of shared mobility, mobility hubs and user characteristics on a national scale. The collected data will provide insights into the conditions that encourage shared mobility adoption, and on the factors that can enhance mobility hub usage. Additionally, the dataset – encompassing socio-economic indicators, travel behaviour and user preferences – will be stored in a open data platform for future research and policy development.

Abstract
This paper investigates the effects of a temporary reduction in road supply on traffic congestion and commuter behavior, using a natural experiment in São Paulo, Brazil. The unexpected closure of a 5 km section of the city’s most important road—a ring road encircling the CBD—in 2018 provides an opportunity to assess short- and long-term traffic adjustments. Using a differences-in-differences (DiD) approach and a high-frequency dataset of identified vehicle counts from more than 1,000 traffic sensors, I show that the affected area lost approximately 5% of vehicles during the period when the overpass was blocked.
I then investigate the possible mechanisms of traffic adjustment and commuter behavior following the reduction in road supply, building on Downs (1962). The road closure led to increased congestion and traffic dispersion to alternative routes (route shifting), with little evidence of departure time adjustments (scheduling shifting) or changes in mode choice—public transportation and cycling (mode shifting).
When the affected road segment reopened, traffic did not fully return to its previous levels, indicating a persistent decline in vehicle flow. This effect is particularly strong on alternative routes, suggesting some degree of stickiness or commuters learning and adopting new routes.
These findings contribute to urban transport policy discussions, highlighting that reductions in road supply, such as street pedestrianization, may not be an effective policy to reduce car dependence. Moreover, such policies can disperse traffic to other areas, and this dispersion effect should be carefully considered in policy design.

Sustainable mobility and small villages: the case of Cilento area (Southern Italy)

Abstract
The work aims to draw guidelines for national and regional public and private stakeholders to design policies and mechanisms for sustainable mobility. The pursuit of these objectives envisages an integrated policy and system approach, both of instruments (strategies, plans and programmes) and of actors (planners, private actors, youth network, civil society). The methodological approach envisages an observation of the sustainable mobility mechanisms of case studies of the Campania region's territory in southern Italy in order to then define guidelines that can have a general impact; starting from the particular in order to favour the general with an approach similar to that of laboratory experimentation. The observation and analysis will start from territorial case studies of intermediate and peripheral areas south of Salerno and in particular in the Cilento area.The analysis of existing spatial planning at different levels, including those related to mobility (Sustainable Urban Mobility Plans; Regional Strategies for Sustainable Development; National Strategy for Inner Areas; National Strategy for Sustainable Development and related sets of indicators; slow mobility paths of walking and/or cycling routes; school mobility commuting to work, mobility of the elderly and differently abled) will aim to provide the essential elements for verifying their strengths and weaknesses and to direct policy makers to favour the involvement of young people and civil society in the process of defining needs and related resolutions for the implementation of sustainable mobility, at different levels and territorial dimensions.

Abstract
In this paper we aim to compare the travel times of cars and bikes in Bari, Italy, which is a car-oriented and car-dominated urban area. Using 2023 OD bike commuting trips data and distance-optimizing corresponding simulated car trips on real-world speed network, we aim to calculate travel time differences between the two modes based on distance classes, age, gender. By using Value of Time (VOT) for Italian car commuting trips we aim to provide an estimate of the Value of Travel Time Savings (VTTS) derived by using the fastest mode. In this way, we aim to provide evidence of wheter and for what types of trips bike is a valid substitute for car. By calculating differences in Value of Time, we can provide economic justification in terms of travel time cost to the choice of one mode over the other for specific trips.
