the speed limits in Town04 #7929

Closed ccconquer closed 6 days ago

ccconquer commented 2 weeks ago

CARLA version: 0.9.15 Platform/OS: ubuntu Problem you have experienced: Regarding the speed limits in Town04, why are the speed limits so high? There are no speed limits for roads after Road_ID52. Is there an issue? Code: xodr_content = self.map.to_opendrive() root = ET.fromstring(xodr_content) speed_limit = None for road in root.iter('road'): print(f"Road ID: {road.attrib['id']}, Name: {road.attrib['name']}, Length: {road.attrib['length']}") for speed in road.iter('speed'): speed_limit = float(speed.attrib['max']) * 3.6 # 转换为 km/h print(f"Speed limit: {speed_limit} km/h") Result: 道路限速

For the roads that have a speed limit, I think the values are already in km/h and not in m/s, so you get the wrong values when multiplying by 3.6.

Hello, as GoodarzMehr says, the speeds in Carla are applied in km/h and not in m/s, by changing this data the speeds should match well
