# Abstract
|
||||||
|
|
||||||
|
This project implements an R-based application for the retrieval, processing, and statistical analysis of aircraft trajectories. Flight data is obtained from the OpenSky Network API, transformed into analyzable trajectory objects using the `trajr` package, and subsequently characterized using established movement ecology metrics. The methodology enables quantitative comparison of flight paths through parameters such as path length, straightness index, and fractal dimension.
|
||||||
|
|
||||||
|
# Introduction
|
||||||
|
|
||||||
|
## Background
|
||||||
|
|
||||||
|
The analysis of movement trajectories constitutes a fundamental aspect of spatial data science, with applications ranging from animal behavior studies to transportation network optimization. In the context of aviation, trajectory analysis provides insights into flight efficiency, airspace utilization, and routing patterns.
|
||||||
|
|
||||||
|
## Objectives
|
||||||
|
|
||||||
|
The primary objectives of this project are:
|
||||||
|
|
||||||
|
1. **Data Acquisition**: Implement robust methods for retrieving real-time flight trajectory data from the OpenSky Network
|
||||||
|
2. **Trajectory Characterization**: Apply established metrics from movement ecology to quantify flight path properties
|
||||||
|
3. **Statistical Analysis**: Perform comparative analysis across multiple flights to identify patterns and distributions
|
||||||
|
|
||||||
|
## Theoretical Framework
|
||||||
|
|
||||||
|
The `trajr` package, originally developed for animal movement analysis, provides a comprehensive toolkit for trajectory characterization. Key metrics employed in this analysis include:
|
||||||
|
|
||||||
|
- **Path Length**: Total distance traveled along the trajectory
|
||||||
|
- **Diffusion Distance**: Euclidean displacement from origin to destination
|
||||||
|
- **Straightness Index**: Ratio of diffusion distance to path length (range 0-1)
|
||||||
|
- **Fractal Dimension**: Measure of path complexity (1 = straight line, approaching 2 = space-filling curve)
|
||||||
|
|
||||||
|
# Methodology
|
||||||
|
|
||||||
|
## Data Source
|
||||||
|
|
||||||
|
Flight trajectory data is obtained from the OpenSky Network, a community-based receiver network providing open access to air traffic surveillance data. The API provides:
|
||||||
|
|
||||||
|
- Aircraft state vectors (position, velocity, heading)
|
||||||
|
- Historical flight tracks
|
||||||
|
- Airport departure and arrival information
|
||||||
|
|
||||||
|
## Data Processing Pipeline
|
||||||
|
|
||||||
|
The analysis workflow consists of the following stages:
|
||||||
|
|
||||||
|
1. **Authentication**: Establish connection to OpenSky API using credentials
|
||||||
|
2. **Query Execution**: Retrieve departure information for specified airport and time window
|
||||||
|
3. **Track Retrieval**: Obtain detailed waypoint data for individual flights
|
||||||
|
4. **Coordinate Transformation**: Convert geographic coordinates to metric distances
|
||||||
|
5. **Trajectory Construction**: Create `trajr` trajectory objects for analysis
|
||||||
|
6. **Statistical Computation**: Calculate trajectory metrics and aggregate statistics
|
||||||
|
|
||||||
|
# Implementation
|
||||||
|
|
||||||
|
The following section will demonstrate the implementation of the methodology using R code snippets.
|
||||||
|
The full analysis is also available in the GUI-based Shiny application.
|
||||||
|
|
||||||
|
## Step 1: API Authentication
|
||||||
|
|
||||||
|
The `getCredentials()` function retrieves API credentials from environment variables, ensuring secure credential management.
|
||||||
|
|
||||||
|
```r
|
||||||
|
creds <- getCredentials(
|
||||||
|
client_id = Sys.getenv("OPENSKY_CLIENT_ID"),
|
||||||
|
client_secret = Sys.getenv("OPENSKY_CLIENT_SECRET")
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 2: Data Acquisition
|
||||||
|
|
||||||
|
Recent departures from Frankfurt Airport (ICAO: EDDF) are queried for a two-hour time window. This airport was selected due to its high traffic volume, ensuring sufficient data availability.
|
||||||
|
|
||||||
|
```{r demo-departures}
|
||||||
|
time_now <- Sys.time()
|
||||||
|
departures <- getAirportDepartures(
|
||||||
|
airport = "EDDF",
|
||||||
|
startTime = time_now - hours(2),
|
||||||
|
endTime = time_now - hours(1),
|
||||||
|
credentials = creds
|
||||||
|
)
|
||||||
|
cat("Departures retrieved:", length(departures), "\n")
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 3: Track Data Retrieval
|
||||||
|
|
||||||
|
The `getAircraftTrack()` function retrieves detailed waypoint data for individual aircraft. The function iterates through available departures until valid track data is obtained.
|
||||||
|
|
||||||
|
```{r demo-track}
|
||||||
|
route_df <- NULL
|
||||||
|
icao <- "N/A"
|
||||||
|
|
||||||
|
if (length(departures) > 0) {
|
||||||
|
for (i in seq_along(departures)) {
|
||||||
|
icao <- departures[[i]][["ICAO24"]]
|
||||||
|
dep_time <- departures[[i]][["departure_time"]]
|
||||||
|
route_df <- getAircraftTrack(icao, dep_time, creds)
|
||||||
|
if (!is.null(route_df) && nrow(route_df) >= 3) {
|
||||||
|
cat("Aircraft ICAO24:", icao, "\n")
|
||||||
|
cat("Track points acquired:", nrow(route_df), "\n")
|
||||||
|
break
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
if (is.null(route_df)) {
|
||||||
|
cat("No valid track data available\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 4: Spatial Visualization
|
||||||
|
|
||||||
|
The geographic trajectory is visualized on an interactive map with leaflet using the `createInteractiveMap()` function. Green and red markers indicate departure and current/final position, respectively.
|
||||||
|
|
||||||
|
```{r demo-route-plot, fig.width=7, fig.height=5}
|
||||||
|
if (!is.null(route_df)) {
|
||||||
|
createInteractiveMap(route_df)
|
||||||
|
} else {
|
||||||
|
cat("Insufficient data for visualization\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 5: Vertical Profile Analysis
|
||||||
|
|
||||||
|
The altitude profile reveals distinct flight phases: climb, cruise, and descent. This temporal representation provides insight into vertical movement patterns.
|
||||||
|
|
||||||
|
```{r demo-altitude-plot, fig.width=7, fig.height=4}
|
||||||
|
if (!is.null(route_df)) {
|
||||||
|
time_minutes <- (route_df$time - route_df$time[1]) / 60
|
||||||
|
plot(time_minutes, route_df$alt, type = "l", col = "red", lwd = 2,
|
||||||
|
main = paste("Altitude Profile -", icao),
|
||||||
|
xlab = "Elapsed Time (min)", ylab = "Barometric Altitude (m)")
|
||||||
|
grid()
|
||||||
|
} else {
|
||||||
|
cat("Insufficient data for altitude analysis\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 6: Trajectory Object Construction
|
||||||
|
|
||||||
|
The `getTrajFromRoute()` function transforms geographic coordinates into a metric coordinate system and constructs a `trajr` trajectory object. This transformation is necessary for accurate distance calculations.
|
||||||
|
|
||||||
|
```{r demo-trajectory-plot, fig.width=7, fig.height=5}
|
||||||
|
if (!is.null(route_df)) {
|
||||||
|
trj <- getTrajFromRoute(route_df)
|
||||||
|
plot(trj, main = paste("Metric Trajectory -", icao))
|
||||||
|
cat("Trajectory object created with", nrow(trj), "waypoints\n")
|
||||||
|
} else {
|
||||||
|
cat("Insufficient data for trajectory construction\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 7: Single Flight Characterization
|
||||||
|
|
||||||
|
The `calculateTrajectoryStats()` function computes comprehensive trajectory metrics. The table format provides a clear overview of individual flight characteristics.
|
||||||
|
|
||||||
|
```{r demo-stats-table}
|
||||||
|
if (!is.null(route_df)) {
|
||||||
|
stats_table <- calculateTrajectoryStats(route_df, icao = icao, format = "table")
|
||||||
|
knitr::kable(stats_table, caption = paste("Trajectory Metrics for Aircraft", icao))
|
||||||
|
} else {
|
||||||
|
cat("Insufficient data for statistical analysis\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Step 8: Multi-Flight Data Collection
|
||||||
|
|
||||||
|
To enable statistical inference, trajectory data is collected for multiple flights. The algorithm attempts to retrieve valid track data for up to five departures in this example.
|
||||||
|
|
||||||
|
```{r demo-multiple-tracks}
|
||||||
|
flight_data <- list()
|
||||||
|
successful_flights <- 0
|
||||||
|
|
||||||
|
if (length(departures) > 0) {
|
||||||
|
max_attempts <- min(10, length(departures))
|
||||||
|
|
||||||
|
for (i in seq_len(max_attempts)) {
|
||||||
|
icao_temp <- departures[[i]][["ICAO24"]]
|
||||||
|
dep_time_temp <- departures[[i]][["departure_time"]]
|
||||||
|
|
||||||
|
route_df_temp <- getAircraftTrack(icao_temp, dep_time_temp, creds)
|
||||||
|
|
||||||
|
if (!is.null(route_df_temp) && nrow(route_df_temp) >= 3) {
|
||||||
|
stats <- calculateTrajectoryStats(route_df_temp, icao = icao_temp, format = "row")
|
||||||
|
if (!is.null(stats)) {
|
||||||
|
flight_data[[length(flight_data) + 1]] <- stats
|
||||||
|
successful_flights <- successful_flights + 1
|
||||||
|
cat("Flight", successful_flights, "| ICAO:", icao_temp,
|
||||||
|
"| Waypoints:", nrow(route_df_temp), "\n")
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
if (successful_flights >= 5) break
|
||||||
|
}
|
||||||
|
|
||||||
|
if (length(flight_data) > 0) {
|
||||||
|
all_flights_stats <- do.call(rbind, flight_data)
|
||||||
|
cat("\nSample size (n):", nrow(all_flights_stats), "flights\n")
|
||||||
|
} else {
|
||||||
|
all_flights_stats <- NULL
|
||||||
|
cat("No valid trajectories obtained\n")
|
||||||
|
}
|
||||||
|
} else {
|
||||||
|
all_flights_stats <- NULL
|
||||||
|
cat("No departure data available\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

## Individual Flight Metrics
|
||||||
|
|
||||||
|

|
||||||
|
|

```{r demo-all-stats-table}
|

if (!is.null(all_flights_stats)) {
|

## Descriptive Statistics
|
||||||
|
|
||||||
|
The `calculateStatsSummary()` function computes central tendency and dispersion measures for each trajectory parameter.
|
||||||
|
|
||||||
|
```{r demo-summary-stats}
|
||||||
|
if (!is.null(all_flights_stats) && nrow(all_flights_stats) >= 2) {
|
||||||
|
summary_stats <- calculateStatsSummary(all_flights_stats)
|
||||||
|
knitr::kable(summary_stats, caption = "Descriptive Statistics Summary")
|
||||||
|
} else {
|
||||||
|
cat("Minimum sample size (n >= 2) not met\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Distribution Analysis: Boxplots
|
||||||
|
|
||||||
|
Boxplots provide a robust visualization of parameter distributions, displaying median, interquartile range, and potential outliers. The red diamond indicates the arithmetic mean.
|
||||||
|
|
||||||
|
```{r demo-boxplots, fig.width=10, fig.height=8}
|
||||||
|
if (!is.null(all_flights_stats) && nrow(all_flights_stats) >= 2) {
|
||||||
|
createBoxplots(all_flights_stats)
|
||||||
|
} else {
|
||||||
|
cat("Minimum sample size (n >= 2) not met\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Distribution Analysis: Kernel Density Estimation
|
||||||
|
|
||||||
|
Density plots employ kernel density estimation to approximate the probability distribution of each parameter. Vertical lines indicate mean (red, dashed) and median (green, dotted).
|
||||||
|
|
||||||
|
```{r demo-density, fig.width=10, fig.height=8}
|
||||||
|
if (!is.null(all_flights_stats) && nrow(all_flights_stats) >= 3) {
|
||||||
|
createDensityPlots(all_flights_stats)
|
||||||
|
} else {
|
||||||
|
cat("Minimum sample size (n >= 3) not met for density estimation\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Distribution Analysis: Histograms
|
||||||
|
|
||||||
|
Histograms with overlaid density curves provide an alternative visualization of parameter distributions.
|
||||||
|
|
||||||
|
```{r demo-histograms, fig.width=10, fig.height=8}
|
||||||
|
if (!is.null(all_flights_stats) && nrow(all_flights_stats) >= 3) {
|
||||||
|
createHistograms(all_flights_stats)
|
||||||
|
} else {
|
||||||
|
cat("Minimum sample size (n >= 3) not met for histogram analysis\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Parameter Interpretation
|
||||||
|
|
||||||
|
The `generateInterpretation()` function provides contextual analysis of the computed trajectory metrics.
|
||||||
|
|
||||||
|
```{r demo-interpretation}
|
||||||
|
if (!is.null(all_flights_stats) && nrow(all_flights_stats) >= 2) {
|
||||||
|
interpretation <- generateInterpretation(all_flights_stats)
|
||||||
|
cat(interpretation)
|
||||||
|
} else {
|
||||||
|
cat("Minimum sample size (n >= 2) not met for interpretation\n")
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
# Discussion
|
||||||
|
|
||||||
|
## Key Findings
|
||||||
|
|
||||||
|
The trajectory analysis reveals several characteristics typical of commercial aviation:
|
||||||
|
|
||||||
|
1. **High Straightness Values**: Commercial flights generally exhibit straightness indices approaching 1.0, indicating efficient direct routing between waypoints.
|
||||||
|
|
||||||
|
2. **Low Fractal Dimension**: Values close to 1.0 confirm that flight paths approximate straight lines, consistent with fuel-efficient routing principles.
|
||||||
|
|
||||||
|
3. **Velocity Patterns**: Mean velocities below typical cruise speeds (800-900 km/h) reflect the inclusion of departure and arrival phases in the trajectory data.
|
||||||
|
|
||||||
|
## Limitations
|
||||||
|
|
||||||
|
- **Temporal Resolution**: Track data granularity varies based on ADS-B receiver coverage
|
||||||
|
- **Sample Size**: Statistical inference is limited by the number of available flights with complete track data
|
||||||
|
|
||||||
|
# Conclusion
|
||||||
|
|
||||||
|
This project demonstrates the successful application of movement ecology metrics to aviation trajectory analysis. The implemented R framework provides a reproducible methodology for flight path characterization and statistical comparison. The `trajr` package proves suitable for aircraft trajectory analysis, offering robust metrics originally developed for biological movement studies.
