Summary

This document is a retraction notice issued by the journal *TRANSPORT* regarding an article originally published in 2006 titled "Providing a Decreasing Connection Probability Model for Urban Street Network" by Hasan Ziari, Hamid Behbahani, and Mohammed M. Khabiri. The paper was retracted in September 2009 because the Editorial Board determined it to be a typical example of plagiarism. The notice explicitly states that the authors failed to cite three earlier published works that contained the original ideas and methods presented in the Ziari et al. paper. These original sources include two papers by B. Jiang and C. Claramunt (2002, 2004) regarding structural approaches to urban street network generalization, and a 2000 work by G. Forbes on urban roadway classification. The original article addressed the problem of urban street classification and congestion. It argued that traditional functional classification systems, which focus primarily on motor vehicle mobility and access, ignore other road users and functions. The authors proposed a novel generalization model for selecting characteristic streets in an urban network to decrease travel delay time and improve reliability. The method relied on graph theory, representing named streets as vertices and intersections as links. The model utilized two measures to assess node status: connectivity (a local measure of direct links) and average path length (a global measure of integration). The authors claimed to use probability theory to calculate the reliability of the network and the probability of free flow, aiming to optimize street arrangement to minimize delay. The retraction notice does not present new findings but rather confirms the invalidity of the original publication due to academic misconduct. The Editorial Board, led by Editor-in-Chief Prof. Adolfas Baublys, declared that the paper was produced without citing the initial original references. Consequently, the journal and the publishing house TECHNIKA formally retracted the article. The notice serves as a public apology and a statement of the journal’s stance against plagiarism, ensuring that the scientific record reflects the true origin of the research concepts, which belong to Jiang, Claramunt, and Forbes, rather than Ziari, Behbahani, and Khabiri.
