Assessment of the Impact Exerted by Closing Road Tunnel on Traffic Conditions on the Example of the DW902 Road in Gliwice (Poland)

Abstract

The article comments upon the impact exerted by closing the tunnel within the DW902 road on traffic conditions in the town of Gliwice. Both the tunnel in question and the town’s road network have been described, and detailed information on the direct vicinity of the tunnel has been provided. The impact of the tunnel closure on traffic conditions has been analysed by comparing traffic parameters and the road situation on the day when the tunnel was closed with those of the preceding day, i.e. when the tunnel was still operational and no significant road network disturbances were observed. For purposes of the analysis of the impact exerted by the tunnel closure on traffic conditions in the town of Gliwice, individual impact zones were defined, radially extending from the tunnel location. In order to achieve the goal of the study, a comprehensive array of available measuring, computational and analytical tools were used at the Office of the Traffic Control Centre of the Municipal Road Administration in Gliwice.
