Abstract

Traffic lights signalling equipment at crossroads are very important. To regulate the procedure for placing traffic lights signalling equipment in Indonesia, the Minister of Transportation of the Republic of Indonesia Regulation Number PM 49 of 2014 regarding Traffic signal system is issued. The regulation above does not regulate how far the minimum visibility from the driver to the traffic light is. The limited space in the queue became a problem related to the views of drivers. Researchers conducted a visibility analysis using Digital Human Modelling (DHM) Tecnomatix Jack. Input variable is the type of vehicle, namely motorcycles, sedans and jeeps and the measured output is the distance from traffic light to the vehicle. A traffic light survey was conducted in Denpasar City, Bali, Indonesia. The anthropometric data of the drivers used Indonesian men, around 50% percentiles with ages ranging from 17 to 47 years from the anthropometric data of Indonesians. The testing of waiting distance is using motorcycles, jeeps, and sedans. The traffic lights used are curved type with the visibility of side lights and top lights. The results obtained that the optimal distance for the left side of the traffic light for motorcycles, jeeps, and sedans are 6.57m, 6.77m, and 6.92m, respectively and side lights up to 11.9 m, 7.64 m and 8.74 m. From the survey results, several traffic lights in Denpasar City still do not meet the minimum required distance and some queues require additional lights that are placed in front of the driver so that they can tackle the limited queuing space.
