Abstract

This work describes a combination of image analysis techniques used to identify vehicles travelling on a bridge with a vectorised modal dynamic analysis that can handle efficiently a large number of wheel loads on the deck at each analysis step-time. In the absence of weight-in-motion data, a randomisation of the traffic flow is proposed to define the weight of the vehicles as a function of their identified size. The methodology is applied to real CCTV recording on a conventional road bridge with a large width-to-span ratio in which the deck is modelled with shell elements. The latter is found to be important to capture the significant contribution of local slab modes to the vibrations along the sidewalks. The dynamic analysis of a large number of traffic records indicate that code-based load cases with long truck convoys lead to unrealistically large contributions of high-order modes and to vibrations that are categorised as uncomfortable, whilst the more realistic traffic flows obtained from image analysis satisfy the comfort criteria based on root-mean-square accelerations.

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 2026-04-08:

  • 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: 7.
  • 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: 7 (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: 2.
  • The number of mentions on the social network X (formerly Twitter): 2 (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:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: https://oa.upm.es/84619/

As a result of the publication of the work in the institutional repository, statistical usage data has been obtained that reflects its impact. In terms of dissemination, we can state that, as of
