Please clarify the scope of 23-FH2 innovation
There are already many commercial solutions available that detect vehicle types/classes, counts, speed, etc. using legacy computations or AI detection from piezo loops, fiber optic sensors, camera images/video, and other WIM stations. Many of the available solutions also provide edge IoT devices that can be powered by solar batteries. It is NOT clear what new innovation this topic is about? Will the innovation be in detection and classification from various sensor/camera data, in deploying algorithms on the edge devices to process big streams of data, in communicating data to the cloud? All of these have already been developed in commercial solutions. Please clarify what I am missing here.

Traffic monitoring is not new. All these devices listed by you are in existence. However, none of them has the ability to fulfill the full spectrum needs of highway travel data collection in terms of vehicle counts, vehicle classification, speed, presence of fogging/smoking travel environment, and the presence of icy and wet pavement condition. The goal of this call of innovation is to devise a sensor or sensor package where all the travel data needs can be gathered and transmitted effectively to different decision makers. Broad capability, on-site and immediate (in-situ) data processing, minimum demand on data transmission are the ultimate goal of this new traffic monitoring device. By the way, none of the current sensors has the high reliability to differentiate electric vehicles from regular gas or diesel powered vehicles. In addition, on the micro mobility front, there is a significant lack of sensors or devices to differentiate electric bicycles, electric scooters from conventional bicycles and scooters.

I am also unclear as to the key innovation needed here. The topic sometimes sounds as though it wants to "add-on" to existing infrastructure, but the approach desired would probably be better served by new cameras with the edge computation capability installed from the start. The latter is of course much more expensive.
