Use the pre-built snapshot JAR. `java -server -Xmx4g -Xms3g -jar gtfs-validator.jar yourGtfs.zip`\n\n2. Import the services provided and build your own validation.\n\n3. Use the gtfs-validator-json and gtfs-validator-webapp according to the directions in those folders. \n\n==============\nValidatorMain\n\nThe ValidatorMain class logs a number of common GTFS errors to Standard Out on the console when run as a JAR. This includes:\n\n * Problems with route names\n * Bad shape coordinates\n * Unused stops\n * Duplicate stops\n * Missing stop coordinates\n * Missing stop times for trips\n * Stop times out of sequence\n * Duplicated trips (same times)\n * Overlapping trips when block_id is present\n * Missing shapes and shape coordinates\n * “Reversed” shapes with directions that do not agree with stop times.\n * Exhaustively going through the calendar and printing active service IDs and number of trips for that day.\n * Dates with no active service\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fconveyal%2Fgtfs-validator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fconveyal%2Fgtfs-validator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fconveyal%2Fgtfs-validator/lists"}
