The TrafficRadar is designed and optimized for Smart City applications:
- Temporary or periodic counting
- Permanent counting
- Traffic information systems
The TrafficRadar unit allows for the collection of traffic data without the need for in-road sensors. The product can monitor two lanes of traffic travelling in the same or opposite direction, monitoring each lane separately. The advanced embedded algorithms ensure that the vehicle length measurement is highly accurate, allowing for Vehicle By Vehicle (VBV) classification.
The device can either be battery powered for short term surveys or can be solar powered for permanent installations. Units comes with a 3G/4G modem and users can specify the way data is collected. It can record either VBV or binned data and can log the data both historically and in real-time. In historical mode the TrafficRadar waits for the user to collect the data, in real-time mode it sends the data automatically to the server at user configurable time periods.
The TrafficRadar can be used in numerous applications:
- Ad Hoc traffic surveys, annual or otherwise
On demand traffic surveys with the rapidly deployable TrafficRadar to cover two lanes of road traffic by simply mounting the device on existing street furniture.
- Road safety audits
Individual vehicle speeds are recorded along with time stamps and lane designation to allow for gap analysis (time in seconds between vehicles) to be reported against speed limit violations to quickly identify dangerous driving behaviour on the road network.
Mounting a radar to traffic signals also allows for ‘speed on green’ data to be captured, once again highlighting road user behaviour in a covert manner.
- One way street surveys
The TrafficRadar will flag reverse direction vehicles to highlight vehicle disciplines on one-way streets. Reports can easily be generated to report on the number of violations and the time of day that they are taking place.
- HGV zone restriction surveys
If there are concerns HGVs are using roads with weight restrictions, the Radar can be rapidly deployed to capture vehicle length data to easily report how many large vehicles are using the route.
The configurable length filters available with the VDA applications means that all vehicles under a certain length can be removed from the data set to easily present all the violations for the duration of the survey.
- Traffic adaptive lighting projects
Permanently installed Radars can provide real-time data feeds for use cases beyond simply capturing traffic data. Streaming this data to street lighting providers allows for decisions to be made on whether to lower lighting levels on certain roads based on live traffic flow information for energy saving purposes.
Alternatively, if a route becomes much busier due to an unforeseen route diversion, street lights can be brightened to illuminate the roads better for a safer road network.
- Speed & flow congestion monitoring
Live traffic data streamed from the TrafficRadars to the VDA-Net platform allows for live speed and flow data to be monitored and alerts raised on the SmartMap when abnormal flow conditions are detected on the network.
Using this data to feed third party live traffic modelling applications, then allows for green light optimisation to take place in an attempt to alleviate congestion and reduce emissions.
- Annual growth reports
Long term collection or sampling of data enables transport planners to see yearly growth on the road network, AADT (annual average daily total) and AAWT (annual average weekday total) are calculated and tracked by VDA to instantly report 5 and 7 days annual growth % for each site.
- Road network demand
Is the road now approaching a point of maximum capacity? When vehicle flows reach a certain point, does the average speed start to dwindle? Has the annual growth attributed to this? By combining flow and average speed reports historically, it is simple to understand if the site is still coping with demand.
- Non-invasive alternative to inductive loop installations
Rather than requiring in-ground sensors, TrafficRadars require no additional sensors to be able to detect road traffic. The Radars will record volume, speed & length data which will give an indication of vehicle classification, however if detailed chassis based classification is required inductive loop technology is the only alternative option.
- Transport planning & road modelling
Using a culmination of all the above data reports, to allow transport planners and road modellers to carry out their jobs.
Transport planning is defined as planning required in the operation, provision and management of facilities and services for the modes of transport to achieve safer, faster, comfortable, convenient, economical and environment-friendly movement of people and goods.
Benchmark: Radar vs Loops
With the advancements of the TagMaster TrafficRadar, which utilises the latest radar technology, it is now possible to detect and record two individual lanes of traffic travelling in the same direction, for example half a dual carriageway with an individual channel per lane. In light of this we feel it’s important to measure the performance against a conventional inductive loop site. There are almost always obscuration issues when dealing with Radar Outstations due to high sided near side traffic, however thanks to state-of-the-art platoon splitting algorithms the majority of far side traffic can now be correctly resolved. Due to the advances in technology and hardware developments for dual carriageway operation, the TrafficRadar has also inherited advanced single carriageway performance.
