The Traffic Pyramid

 

There are four different levels of traffic data. Each provides a different depth of understanding of an area’s roadways. When put together, they provide a picture of the transportation flow. MetroTech aggregates all area of transportation info, including intersection visual and sensor data to analyze and understanding every road, lane, signal and more.

The more detailed and current the data, the more it is worth to users

1. Mapping Data

Mapping data is the basic framework from which all other data sources are derived (names of roads and distances). It provides MetroTech a general understanding of the roadways. These include:

  • Street names
  • Distances
  • Intersections
  • Highways and ramps
2. Static Data

This information provides a more detailed interpretation of each street, including:

  • Number of lanes
  • Speed limits
  • Direction of travel
  • Signs
  • Signals
3. Dynamic Data

A roadway changes from minute to minute. Dynamic data reports semi-predictable events. Currently, this data is reported within 15 to 30 minutes.

  • Roadwork
  • Rush hour
  • Spontaneous Bottlenecks
  • Detours
  • Traffic Accidents
4. Real-Time Data

Unlike any other system, MetroTech is able to accomplish this top level of the pyramid through the use of live camera feeds. They are able to see exactly what is going on at the lane level. Prior to MetroTech, Dynamic Data was thought to be as close to real-time as possible. Real-time data can report:

  • Lane hazards
  • Stalls
  • Smaller incidents
  • Immediate situations
  • Pedestrians and crosswalks
  • Wrong way driver alerts
