Origin-destination

What is Origin-Destination?

Origin-Destination (OD) studies are used to determine travel patterns of traffic in an area of interest for a period of time. While OD data are useful in different traffic planning projects, traditional data collection methods such as road-surveys or license plate matching are expensive and inefficient. Fortunately, SMATS provides a cost-effective and efficient solution.

How it Works?

By setting up a network of SMATS Bluetooth and Wi-Fi sensors around the OD points of interest, iNode uses MAC address tracking and matching to determine individual trip patterns and the origin-destination matrix. The combination of Bluetooth and Wi-Fi detections also improves the sample size of the data, which is an important factor in OD studies.

Inputs

Sensors/Zones Selection

Nodes: Origin (entry) and destination (exit) points which form the OD matrix. A trip starts from an Origin and ends at a Destination sensor.

Include: Sensors that should be optionally included in the list of trips between nodes. These are the waypoints between an origin and a destination point.

Must Include: The sensor(s) that must always present in the list of the trips.

Must Exclude: The sensor(s) used to exclude the trips including this sensor.

Time and Date Selection

Select days and hours for OD analysis. Multiple days and time slices can be selected. Multiple days selection are aggregated and the generated reports are reported separately for each time slice such as AM and PM peaks.

Outputs

Raw Trips Data

The raw trips report includes the list of all trips discovered between the origin and destination points. Each trip data include the vehicle’s unique ID (such as MAC address) or trip ID, the origin point, selected waypoints, and the destination point. The travel time between each two sensors and the total trip travel time are also reported.

Average Trips Data

The discovered trips list data are aggregated to generate trip average data including, the number of vehicles taking the same trip route, average, minimum, maximum, and 95th percentile travel time for a certain route.

OD Matrix

The OD matrix report includes the number of trips between each origin and destination pair, average travel time, and trip percentages (distribution)
