Abstract
En este artículo se evalúa la vulnerabilidad de la red de carreteras del sur del municipio de Murcia ante la inserción del trazado ferroviario de la línea de Alta Velocidad, determinando las variaciones de tiempo en los desplazamientos con origen en los barrios y pedanías situados al sur de la vía ferroviaria hacia los lugares de mayor interés de la ciudad de Murcia. En la metodología se emplean Sistemas de Información Geográfica (SIG) para generar modelos de la red de transporte del municipio de Murcia referidos al escenario previo a la integración de la alta velocidad, escenario de inserción en superficie y escenario de inserción soterrada, para dos tipos de movilidad: a pie y mediante vehículo motorizado. Los costes de tiempo de desplazamiento obtenidos de cada modelo se analizan y comparan estadísticamente obteniendo las variaciones. Los resultados revelan que la inserción en superficie implicaría un incremento de coste en los desplazamientos, mientras que la inserción soterrada reduciría los tiempos de desplazamiento y mejoraría la accesibilidad.
This article assesses the vulnerability of the road network in the south of the municipality of Murcia to the insertion of the railway line of the High-Speed line, determining the time variations in movements originating in the neighborhoods and districts located south of the railway to the places of greatest interest in the city of Murcia. In the methodology, Geographic Information Systems (GIS) are used to generate models of the transport network of the municipality of Murcia referring to the scenario prior to the integration of high speed, scenario of surface insertion and scenario of underground insertion, for two types mobility: on foot and by motorized vehicle. The travel time costs obtained from each model are statistically analyzed and compared obtaining the variations. The results reveal that surface insertion would imply an increase in travel costs, while underground insertion would reduce travel times and improve accessibility.
