Estudio de tránsito y propuesta de mejora de la intersección av calle 80-conexión Lisboa en la ciudad de Bogotá

Abstract

The implementation of Bogotá's first Land Development Plan (POT), established under Decreto 619 of 2000 and fully enacted in 2004, introduced stringent land-use restrictions. These regulations restricted industrial development and high-environmental-impact zones within the city's central areas, progressively driving the relocation of warehouses, distribution centers, and manufacturing plants toward the western periphery—such as the Fontibón Free Trade Zone—and adjacent municipalities of the Bogotá Savanna (including Funza, Mosquera, and Cota). While this regional industrialization has stimulated the labor market for both suburban residents and capital commuters, it has simultaneously caused operational demand on Avenida Calle 80 to severely outstrip its service capacity during peak hours. As a primary western arterial exit, Calle 80 provides a critical cross-city connection, intersecting high-capacity corridors such as Avenida NQS, Avenida 68 (currently undergoing intervention for a new TransMilenio trunk line), Avenida Boyacá, and Avenida Ciudad de Cali. Additionally, it features exclusive Bus Rapid Transit (BRT) lanes that converge at Portal 80, an intermodal hub facilitating commuter bus routes to the surrounding Savanna municipalities. In this context, critical traffic flows are observed during the morning peak from 6:00 a. m. to 8:00 a. m., a window where vehicular demand exceeds the infrastructure's design capacity. This bottleneck is further exacerbated by a roadway bottleneck that narrows the layout from four to two lanes, resulting in a deficient Level of Service (LOS) that is highly vulnerable to traffic incidents or mechanical failures. The direct impact of this bottleneck is reflected in disproportionately prolonged travel times: whereas a trip under free-flow conditions between Portal 80 and the Siberia roundabout takes approximately 15 minutes, historical Google Maps server metrics indicate that during critical operational windows, travel times escalate to between 60 and 90 minutes. Consequently, this research paper proposes the development of two geometric design alternatives aimed at optimizing traffic circulation and operational capacity along the corridor. These alternatives will be formulated based on a traffic diagnosis of current conditions and subsequently evaluated against projected traffic volumes using traffic micro-simulation. The methodological objective is to contrast their operational performance to select the technically optimal solution that addresses the mobility requirements for users at the Avenida Calle 80 - Transversal 120 (Lisboa connection) intersection.
