Road Safety Audit (RSA) is a formal procedure for assessing accident potential and safety performance of new and existing roads. RSA is an efficient, cost effective and proactive approach to improve road safety. It is proved that RSA has the potential to save lives. RSA appears to be an ideal tool for improving road safety in India, as basic and accurate data on accidents have yet to be collected. The study aims to evaluate Road Safety Audit of a section of four - lane Madurai - Chennai, National Highway (NH) - 45 and will focus on evaluating the benefits of the proposed actions that have emanated from deficiencies identified through the audit process. After conducting RSA, it is found that trucks are parked on highway which reduces the effective width of carriageway and creating traffic hazards to high speed moving traffics. Unauthorized median openings were found which should be immediately closed. Missing road and median markings to be done and speed signs should match with speed. Access and service lanes are also in deficit which requires immediate improvement. The most Vulnerable Road User (VRU) i.e. pedestrians and cyclists facilities near habitations are lacking and needs to be facilitated on priority.

Comparative Comparison of Qualitative Criteria for Locating Art Street from the Perspective of Citizens and Experts
The public space in the city is the platform for the manifestation of cultural values. Locating and improving the quality of these spaces creates interaction between citizens and space. In the meantime, identifying and classifying the main spatial qualities under the title of Art Street is an effective step to locate and improve the quality of urban spaces. Such a street is organized with the focus on art and provides the possibility of two-way communication between people and art, or in other words, urban interactive art (public art). The result is the role of citizens as creators of Art works and increasing their belonging to the environment. The present study seeks to achieve the qualitative components affecting the locating of Art Street and tries to interpret the concept of street art, physical, social and perceptual criteria for the locating and organizing of Art Street. For this purpose, by studying the relevant theoretical foundations, the components and criteria of Art Street were collected and classified from the perspective of experts. From their viewpoint the components of environmental quality affecting the desirability of Art Street are classified into four dimensions: physical, traffic, socio-cultural and environmental. In the next step, based on theoretical foundations, a questionnaire was distributed among the citizens in three selected sequences, including a part of the three axes of Valiasr Street, Enghelab and North Kargar street and the qualitative dimensions and locating criteria of Art Street were extracted from their point of view and classified Then, a comparative comparison of the locating criteria of Art Street from the perspective of citizens and experts was performed. According to the research findings, the criterion for the existence of uses related to art and leisure and the continuity and flexibility of sidewalks is one of the main criteria for locating Art Street. the presence of activists such as artists and art students and functions such as art galleries, colleges and art and craft markets is the main factor in the successful location of Art Street. Also, the physical integration in the components, the cohesion of functional nodes, and the ability to diversity and fluidity of functions are the main criteria representing Art Street.
