Complete guide to implementing and working with the General Traffic Signal Specification (GTSS).
GTSS Overview
Welcome to the comprehensive documentation for the General Traffic Signal Specification. Whether you’re a traffic engineer, system integrator, or city planner, this guide will help you understand and implement GTSS-compliant traffic signal information. GTSS Consits of 4 text (.txt) files each with their own set of parameters seperated by a comma.
agency.txt
agency.txt identifies the agnecy information associated with the traffic signals defined in the other GTSS files. Parameters include the agency ID, name, web address, timezone and email contact.
signals.txt
signals.txt lists signal ID, latitude and longitude information for the center of the intersection, and street names associated with each direction.
phases.txt
phases.txt defines phases and the lane and movement type through the intersection, number of lanes, compass bearing of the approach and the posted speed limit.
detectors.txt
detectors.txt defines channels associated with phases for a specific signal, where these detection areas are in relation to stop bar and size, and expected objects are detected.
