Abstract

Public Authorities are responsible for setting speed limits on roads. It is obvious that the modification of speed limits affect travel time. Also, there are many academic studies highlighting the relationship between vehicle speed and other particular isolated social costs, such as speed and accidents, speed and pollution or speed and fuel consumption. However, there are very few comprehensive studies on the subject of optimum speed limits. Furthermore, when Public Authorities modify speed limits usually they justify the measure to achieve a particular goal. The aim of this paper is to develop a comprehensive methodology that relies on cost-benefit analyses to determine the optimum speed limit for a particular road. The methodology is then applied to two recent case studies in Spain. In the first one, the Authorities decreased speed limits on national highways from 120 to 110 km per hour to save fuel. In the second case, the Authorities also reduced speed limits on the M − 30 ring road from 90 to 70 km per hour on specific days to reduce pollution. It seems that the Authorities might not always perform a technical analysis of these measures before implementing these policies.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-27:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 27.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 26 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 10.
  • The number of mentions in news outlets: 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

Project objectives

El presente estudio persigue los siguientes objetivos: analizar la relación entre los límites de velocidad y sus costos sociales asociados; desarrollar una metodología integral basada en análisis de coste-beneficio para determinar el límite de velocidad óptimo en una vía; aplicar dicha metodología a dos casos recientes en España, uno relacionado con la reducción del límite de velocidad en autopistas nacionales de 120 a 110 km/h para ahorrar combustible y otro con la disminución de 90 a 70 km/h en la M-30 para reducir la contaminación; evaluar si las autoridades públicas realizan análisis técnicos previos a la implementación de estas medidas; y caracterizar el impacto de las modificaciones de límites de velocidad en el tiempo de viaje y en objetivos específicos de política pública.

Most relevant results

El estudio presenta una metodología integral basada en análisis coste-beneficio para determinar el límite de velocidad óptimo en carreteras. Los resultados más relevantes son: se aplicó la metodología a dos casos recientes en España; en el primero, la reducción del límite de 120 a 110 km/h en autopistas nacionales buscaba ahorro de combustible; en el segundo, la disminución de 90 a 70 km/h en la M-30 en días específicos pretendía reducir la contaminación; se evidencia que las autoridades no siempre realizan análisis técnicos previos a la implementación de estas medidas; finalmente, se destaca la importancia de evaluar integralmente los efectos sociales y económicos antes de modificar límites de velocidad.
