A Traffic Observer is responsible for collecting and reporting data on traffic conditions, including volume, speed, and type of vehicles. They may also be responsible for operating traffic control devices, such as traffic lights and signs. Here are some of the key job responsibilities of a Traffic Observer:

1. Collect and report data on traffic conditions

Traffic Observers collect data on traffic conditions, including volume, speed, and type of vehicles. They may use a variety of methods to collect this data, such as visual observation, traffic counters, and speed detectors. This data is used to improve traffic flow and safety.

• Monitor traffic flow and identify congestion
• Count and classify vehicles
• Measure traffic speeds
• Record traffic incidents and accidents

2. Operate traffic control devices

Traffic Observers may also be responsible for operating traffic control devices, such as traffic lights and signs. They ensure that these devices are functioning properly and that they are providing clear and accurate information to drivers.

• Set up and maintain traffic control devices
• Monitor traffic signals and make adjustments as needed
• Respond to traffic incidents and emergencies

3. Enforce traffic laws

Traffic Observers may also be responsible for enforcing traffic laws. They may issue citations to drivers who violate traffic laws, such as speeding, running red lights, or driving under the influence of alcohol.

• Issue citations for traffic violations
• Assist law enforcement officers with traffic investigations

4. Provide customer service

Traffic Observers may also provide customer service to the public. They may answer questions about traffic conditions, directions, and road closures. They may also provide assistance to motorists who are experiencing problems, such as flat tires or dead batteries.

• Answer questions about traffic conditions
• Provide directions and road closure information
• Assist motorists with problems
