Abstract

Abstract: This research explored the integrated effect that several mobility scenarios had on traffic performance, conflicts, global and local pollutants, and emission-related costs on a University Campus. Emphasis was given to the campus parking areas. It was hypothesized that the implementation of a new direct access to the campus without any capacity restriction may be worse for the overall network performance. A well-calibrated and validated modeling platform of traffic, emissions and safety was used to examine different traffic scenarios in the University of Aveiro, Portugal. These included the replacement of traffic lights by roundabouts, a new direct access to campus and some parking areas, increasing campus walkability and introduction of speed humps on main crosswalks. The analysis was performed both link-by-link and in the overall study area. Mobility scenarios with a new direct access to the campus yielded average reductions up to 9% in both costs and local pollutants (carbon monoxide, nitrogen oxides and hydrocarbons), and 36% and 32% for the number of stops and traffic conflicts, respectively. Nonetheless, additional traffic conflicts can be expected within campus after the implementation of those scenarios compared to the existing situation when no traffic capacity restrictions are assumed.
