Traffic Impact Study – Pomezia

General overview and objectives

As part of urban planning and commercial mobility, we have developed a study of the traffic impacts associated with the construction of a new multi-sector shopping centre in Pomezia. The assignment, commissioned by ESCAS S.r.l., was aimed at verifying accessibility and traffic conditions. Furthermore, the analysis was conducted in accordance with regional and national regulations, providing essential technical input for the authorisation procedure.

Territorial analysis, data and surveys

The activities included territorial and transport analysis of the reference area. In particular, we used ISTAT data, socio-economic databases and Floating Car Data (FCD) from black boxes installed in vehicles. In addition, we reconstructed the origin/destination flows, described weekday and holiday traffic levels, measured travel speeds, and identified the main congestion points. At the same time, road surveys were conducted during peak hours on weekdays and days before public holidays in order to validate the entire information framework.

Microsimulation model and scenarios

The transport assessment was carried out by implementing a microsimulation model calibrated to actual traffic conditions. We simulated short- and medium-term scenarios, including up to six different configurations during morning and evening peak hours. This made it possible to estimate journey times, average speeds, delays and service levels at the most critical road junctions.

Results and intervention measures

The analysis made it possible to identify the main critical issues of the proposed configuration. Furthermore, it enabled preliminary design solutions to be defined for the adaptation of the road network. Through this approach, therefore, we have ensured a data-driven assessment that is replicable and consistent with EIA standards. Consequently, the study provides a solid basis for the subsequent phases of urban and infrastructure planning for the new commercial hub in Pomezia.
