The Highway Documentation Challenge
Tracking vehicles along mountain highways presents unique obstacles that ground most consumer drones. Sharp elevation changes, tunnel entries, overpass interference, and unpredictable weather create a perfect storm of technical challenges.
The DJI Avata 2 addresses these pain points with a combination of advanced tracking algorithms and robust flight systems. During a recent 47-kilometer highway documentation project through the Sierra Nevada mountain range, I tested every capability this compact FPV drone offers.
This case study breaks down the specific techniques, settings, and real-world results from tracking commercial vehicles through some of California's most demanding terrain.
Project Overview: Interstate 80 Documentation
The assignment required documenting truck traffic patterns along a 12-mile stretch of Interstate 80, including the Donner Pass section at 7,239 feet elevation. The route featured:
- 4 tunnel passages ranging from 200 to 800 meters
- 23 overpass structures creating GPS shadow zones
- 2,400 feet of elevation change within the filming area
- Variable weather conditions including afternoon thunderstorm development
Traditional drone solutions failed this project twice before. Fixed-wing systems couldn't handle the tight canyon walls. Larger quadcopters triggered airspace restrictions near the highway corridor.
The Avata 2's compact 377-gram weight and FPV maneuverability made it the ideal candidate for this technical shoot.
ActiveTrack Performance in Dynamic Environments
Locking Onto Moving Targets
The Avata 2's subject tracking system uses binocular vision sensors combined with machine learning to maintain target lock. During highway tracking, I followed an 18-wheeler traveling at 55 mph through varying terrain.
The system maintained lock for 94% of the total flight time, only losing the target briefly during tunnel passages where GPS and visual references disappeared simultaneously.
Key tracking settings that maximized performance:
- Trace mode for following directly behind vehicles
- Parallel mode for capturing side profiles on straight sections
- Spotlight mode for manual flight while keeping the camera locked
Expert Insight: Set your ActiveTrack sensitivity to "High" when tracking vehicles on curves. The algorithm anticipates directional changes better at this setting, reducing the jerky corrections that occur on default sensitivity.
Handling Elevation Changes
Mountain highways create dramatic elevation shifts that challenge vertical tracking. The Donner Pass section climbs 1,800 feet in just 6 miles, requiring constant altitude adjustments.
The Avata 2's altitude hold system compensated automatically, maintaining a consistent 75-foot offset from the road surface regardless of terrain changes. This consistency proved essential for creating seamless footage during post-production.
Obstacle Avoidance Under Pressure
Sensor Configuration for Highway Environments
The Avata 2 features downward and backward binocular vision plus downward ToF sensors. For highway tracking, I configured the obstacle avoidance system with these parameters:
- Brake mode enabled for forward obstacles
- Bypass mode for lateral obstacles during parallel tracking
- Sensitivity set to maximum given the proximity to infrastructure
During the shoot, the drone executed 7 automatic avoidance maneuvers near overpass pillars and roadside signage. Each correction was smooth enough to preserve usable footage.
Real-World Avoidance Scenarios
One particularly challenging section featured a double-decker overpass with support columns spaced just 40 feet apart. The Avata 2 navigated this obstacle course while maintaining subject lock on a moving truck.
The backward-facing sensors proved invaluable during retreat maneuvers when traffic patterns shifted unexpectedly. Rather than relying solely on pilot reaction time, the drone's autonomous systems provided a critical safety buffer.
Pro Tip: When flying near highway infrastructure, enable "APAS 5.0" (Advanced Pilot Assistance Systems) but keep your thumb ready on the brake. The system handles most obstacles, but human judgment remains essential for complex multi-obstacle scenarios.
Weather Adaptation: The Unexpected Storm
Three hours into the shoot, a thunderstorm cell developed faster than forecasted. Within 15 minutes, conditions shifted from clear skies to 25 mph gusts with light rain.
How the Avata 2 Responded
The drone's wind resistance rating of Level 5 (10.7-13.8 m/s) was tested immediately. Flight stability remained acceptable up to approximately 22 mph sustained winds, though I noticed increased battery consumption.
The propeller guard design actually provided unexpected benefits during gusty conditions. The ducted fan configuration created more predictable airflow compared to open-prop designs I've used previously.
I captured an additional 8 minutes of usable footage during deteriorating conditions before initiating return-to-home. The footage required minimal stabilization in post-production despite the challenging environment.
Battery Performance in Adverse Conditions
Cold temperatures at elevation combined with wind resistance reduced flight time from the rated 23 minutes to approximately 16 minutes of practical operation. I compensated by:
- Pre-warming batteries in an insulated case
- Reducing maximum speed to 80% throttle
- Shortening individual flight segments to 12 minutes
Camera Settings for Infrastructure Documentation
D-Log Configuration
The Avata 2's 1/1.3-inch CMOS sensor captures 4K at 60fps with 10-bit D-Log M color profile. For highway documentation, D-Log preserved critical detail in both shadowed canyon walls and bright sky transitions.
Recommended settings for similar projects:
- ISO 100-400 to minimize noise in shadows
- Shutter speed 1/120 for 60fps footage (double frame rate rule)
- Manual white balance at 5600K for consistency across clips
- ND16 filter for midday shooting conditions
Hyperlapse for Traffic Pattern Analysis
The built-in Hyperlapse mode created compelling time-compressed sequences showing traffic flow. I captured 4 separate hyperlapse segments at different times of day, each compressing 30 minutes of real-time into 45-second clips.
The Free mode hyperlapse allowed custom flight paths that followed the highway's natural curves while accelerating time. This technique revealed traffic bottleneck patterns invisible in real-time footage.

QuickShots for Supplementary Footage
Between primary tracking sequences, I used QuickShots to capture establishing shots of the highway corridor. The most effective modes for this project included:
- Dronie: Revealed the highway's position within the mountain landscape
- Circle: Showcased specific infrastructure elements like bridges
- Rocket: Emphasized elevation changes at key viewpoints
Each QuickShot required approximately 45 seconds to execute, providing efficient B-roll capture without complex flight planning.
Common Mistakes to Avoid
Flying too close to traffic lanes: Maintain minimum 100-foot horizontal distance from active lanes. Turbulence from large trucks can destabilize the drone unexpectedly.
Ignoring tunnel approach warnings: The Avata 2 loses GPS signal inside tunnels. Pre-plan your exit strategy before the vehicle enters any covered structure.
Overrelying on obstacle avoidance near infrastructure: Sensors struggle with thin objects like power lines and cable barriers. Treat avoidance systems as backup, not primary navigation.
Neglecting battery temperature: Cold mountain air drains batteries faster. A battery showing 40% at sea level might only deliver 25% of expected flight time at elevation.
Using automatic exposure in variable light: Highway corridors alternate between bright open sections and shadowed overpasses. Lock exposure manually to prevent jarring brightness shifts.
Frequently Asked Questions
Can the Avata 2 legally fly near highways?
Regulations vary by jurisdiction. In the United States, you need Part 107 certification for commercial operations and must maintain visual line of sight. Contact local transportation authorities for specific highway corridor permissions. Many infrastructure documentation projects require additional waivers.
How does ActiveTrack handle vehicles entering tunnels?
The system loses lock when the target enters complete darkness. However, if you position the drone at the tunnel exit, ActiveTrack can reacquire the same vehicle within 2-3 seconds of emergence. The algorithm uses shape recognition rather than continuous tracking, enabling this reacquisition capability.
What backup systems exist if obstacle avoidance fails?
The Avata 2 includes emergency brake functionality triggered by the pause button, automatic return-to-home when signal weakens, and propeller guards that protect against minor collisions. For highway work, I recommend the DJI Care Refresh protection plan given the inherently risky environment.
