Another great project has been accomplished, among other things, thanks to DataFromSky analysis! DataFromSky has made a traffic study of a corridor in the city of Fairfield in Connecticut, U.S.. The data were used for an extensive Safety analysis of the whole corridor called Black Rock Turnpike. The study, created by The Connecticut Metropolitan Council of Governments (MetroCOG) and FHI, identifies strategies to create a safe and attractive pedestrian environment, a robust infrastructure for bicyclists, and linkages between residential areas and the shops, businesses and restaurants along Black Rock Turnpike.
Black Rock Turnpike is a major arterial that serves one of the city’s largest business and commercial districts. According to the estimates, approximately 20,000 vehicles utilize this corridor every day. As the results of the analysis show – although Black Rock Turnpike has a posted speed limit of 50 km/h (30 miles/h), the average speeds are between 55 – 65 km/h (35-40 miles/h). The road widths, speed, high traffic volume and numerous curb cuts create an unsafe and uninviting pedestrian environment. Click on this link to read more about the whole project.
However, what is truly remarkable about this analysis is the method how the data were recorded and analyzed. To be able to cover the whole corridor, which is roughly 1,3 km in length, up to 8 drones recording at the same time were needed! This allowed us to analyze the corridor as a complex scene, obtain the complete trajectories of vehicles for the whole analyzed route and create the detailed Origin-destination statistics! What were the key conditions for the successful analysis?
- top-down view position (bird’s eye perspective)
- space overlap – at least 10 % of overlap in the analyzed area from each side
- time overlap – all the drones started filming at the exact same time
Take a look at the video of raw output of 8 drone videos merged together:
New video analysis comes from Czech Republic and measures the speeding!
In this demonstration survey, we tracked 204 vehicles which traveled 114 kilometers in total, averaging 555 m per vehicle. The average speed was 34,5 kph.
The video is displaying the sections with maximal speed allowed and highlights vehicles that have exceeded this speed. In the DataFromSky Viewer, you can create such a measured area simply using a polygon, where you can define the conditions under which the alert should appear (e.g. to which categories of vehicles does the rule apply, speed range etc.).

When carrying out a complex traffic study, it may be difficult to map the entire traffic situation, especially with traditional methods. Using a solution in form of traffic research from air with a drone and DataFromSky software, all movements are recorded down and analyzed to the smallest detail for unlimited data. In addition to junctions and road sections, the system is also suitable for parking areas, events, station environments or terminals.
The benefits of traffic research from the aerial video:
- accurate data about traffic flow (counts), turning movements, speed, acceleration, travel time, stationary time (queing time) and many other traffic parameters
- reliable, detailed research without influencing traffic behavior (inconspicuous solution)
- full traffic research, almost without a human intervention
- tool to improve traffic safety
- perfect communication tool for organizations, citizens and politics
Simple insight into all data
The knowledge in form of a aerial video with exact traffic parameters, speed measurements and identification of inappropriate or dangerous behavior is a very powerful communication tool for organizations, citizens and politicians alike. Moreover, it is fairly easy to evaluate, or use the results immediately in programs for traffic simulation models such as VISSIM.
Our partner in the BENELUX region – Roelofs – has recently carried out such complex traffic analysis accross the Netherlands using the drones to analyse the crossroads – especially roundabouts and signalized intersections.
Speed-based trajectories in the analyzed area
The results obtained thanks to DataFromSky were further used to create a simulation model in VISSIM, using the real data about: vehicle categories, speed and acceleration in crossroad, intensities on each lane, vehicle gap time and origin destination statistics. This is the most accurate simulation you can achieve by using real world data! If you want to get more detailed information about the analysis results, click here .
