BLUECITY AI VS. RADAR TECHNOLOGY

The popularity of radar for traffic operations is being challenged by a new technology. How does lidar technology compare with radar?

Traffic data collection is an important tool for cities and towns when decisions need to be made about road systems, and many options for collecting traffic data exist. Radar is a popular choice for traffic operations departments who plan and control the movement of vehicles over streets and highways, and whose mandate it is to make sure this is done efficiently and safely. Radar can detect the presence of vehicles allowing traffic operations departments to communicate and make changes to the timing of traffic light signals.

While radar has been used reliably to collect traffic information over many years, there are still some drawbacks to the use of radar. These include:

As the presence of other road users, such as cyclists, on the road continues to increase, vehicles must share the road with cyclists in a safe and efficient manner. The availability of data regarding pedestrians and cyclists is becoming a priority when choosing a method for traffic data collection. Lidar is a multimodal technology that offers reliable traffic data about all road users.

Radar is an excellent option for 24/7 vehicle detection, as it is able to reliably detect vehicles in poor lighting and bad weather. Radar can be used when detailed information about types of road users or safety metrics are not required.

Bluecity AI is an ideal cost-effective solution that can be used by multiple municipal departments, including transport planners, city engineers, and operations and road safety departments. It is an excellent choice when multimodal traffic data collection in all weather and lighting conditions is required.

Lidar sensors capture data anonymously, effectively eliminating concerns regarding private data being collected and stored. What’s more, Bluecity iQ platforms uses artificial intelligence to power advanced safety analytics and offers better visualization of the data captured as well as automated traffic signal performance measures.

PRIVACY QUESTIONS

Short answer: No

Radar is a method that is used by traffic operations departments to guide decisions about road systems. It cannot provide the type of information required by traffic planners to define future policies, goals, investments, and planning designs for future needs. Radar cannot provide multimodal data or advanced safety metrics.

Short answer: No

Radar can only detect the presence of a vehicle. It is not able to distinguish between types of vehicles, for example, buses, trucks or motorcycles, nor can it detect the presence of cyclists and pedestrians.

Short answer: Yes

The hardware costs of installing radar at intersections can be expensive because more than one sensor is needed. Furthermore, to install radar, the ground must be dug up so the wires can be installed. This necessitates the closure of roads which becomes an inconvenience to road users.

Short answer: Yes

Like lidar sensors, radar is able to provide reliable traffic data 24/7, regardless of the lighting and weather conditions.

RADAR

REVIEW SUMMARY

Pros

Radar installed at intersections is a great choice because it detects the presence of vehicles in all types of lighting and weather conditions. When it detects the presence of vehicles at an intersection, traffic light timing can be optimized.

Cons

Radar can be an expensive choice because roads need to be dug up in order to install the required wiring, and this causes road closures. More than one sensor is needed for each intersection. Radar is also not able to distinguish between the different types of road users.

Best Alternative

Bluecity’s solution is a unique, cost-effective solution that allows planners to capture multimodal traffic data in real-time 24/7. Its lidar sensors are easy to install and maintain and most intersections require only one sensor. It leverages artificial intelligence to power advanced safety analytics that help identify dangerous intersections and improve road safety.

Bluecity is a modern solution for traffic data collection, traffic actuation and safety analytics.
