DEPLOYMENT AND UTILISATION OF SMART INFRASTRUCTURE PERFORMANCE ANALYSER (SIPA)- VERIFICATION OF REPLICABILITY IN INTRICATE INTERSECTIONS

The development of Smart Infrastructure Performance Analyzer (SIPA) is a commendable effort for an evaluation of Intelligent Transportation Systems (ITS) implementations, particularly where the focus has been put on the impact by ETC or AHS operations. The paper explores SIPA as vital tool for highlighting the potential competency of ITS roadwork. Further, it delineates outcomes of the verification tests juxtaposing the replicated traffic and vicinity environment with what has happened in the real-world using a structurally intricate intersection. The major features of SIPA are described as follows: (1) enables replications of each maneuvering behavior of individual vehicles; (2) enables replications of each behavior of vehicles which are operating along intricate road alignments; and (3) enables a bird's eye view of the state of affairs of roads and roving vehicles. The project evaluation, if anything, carries more weight due to the fact that a higher efficiency and effectiveness in roadwork projects are being sought in Japan. More importantly, the roadwork projects which are now planned or having been completed are sturdily and rigorously subjected to pre- and post-evaluations. Additionally, the use of a public involvement (PI) approach, which convenes participants from the community, boosts transparency and accountability for the roadwork projects. Both needs and effectiveness derived from the project are proclaimed to road users. In this respect, the competency of SIPA is envisaged not only as a salient tool of pre-evaluation but also a proactive tool to proclaim project efficacy. SIPA has an edge particularly when replicating the reconstruction work for a structurally intricate intersection. The inherent difficulty of simulation of vehicle maneuvering behavior at such intricate intersections encapsulates the advantageous features offered by SIPA.
