The study was conducted on an urban roadway segment in Lima, Peru, characterized by high levels of traffic congestion. The objective was to evaluate the implementation of a road diet strategy with the incorporation of micromobility corridors. Unlike previous studies, the roadway serves a dual urban and interurban function, connecting Lima with cities in the central region of the country, resulting in more complex operating conditions and critical Level of Service (LOS F) conditions. Initially, the existing conditions were modeled, and subsequently, a geometric redistribution of the roadway was proposed. The intervention does not involve the conventional lane reduction (4 to 3 lanes), but rather a functional reconfiguration that increases operational performance, increasing from 4 to 5 effective lanes and incorporating 2 exclusive side lanes for micromobility. Both scenarios were microsimulated in PTV Vissim, with calibration using the Wiedemann 74 car-following model and validation through metrics such as MAPE and GEH. The results showed improvements in Level of Service from F to D, as well as reductions in travel time, although queue delay increased, exceeding the results reported in previous studies. The road diet significantly improved roadway performance under high congestion and complex functional characteristics.
