What is Ranking and how does it work?
What is Ranking?
Ranking allows you to compare the situation of your street or street segment with other streets. You can compare each street with other streets in your own neighbourhood or, via your own private dashboard, based on your own street profile.
The street profile, which you can define yourself on this site from your dashboard, shows the main characteristics of your street. It is therefore very useful to fill in your "street profile" carefully in order to make the best use of the ranking.
Ranking makes use of the typical traffic data. See article "Network data: observed, typical and relative traffic data" for more info on this type of data.
You can access the ranking in two different ways:
1. On the home page of www.telraam.be.
Click on your street segment, then on "More details" (bottom right of the screen).
This will take you to the page containing all the data collected by your Telraam. And on this page, you will find the Ranking option:
You can also view the ranking via your dashboard:
From your dashboard, you can then refine the comparison of streets with specific filters:
How to use Ranking?
When you arrive on the ranking page, you can select the streets you want to compare your street segment with. You have 6 options:
Comparison with streets that belong to the same network as your street segment
Comparison with streets within a radius of 3 - 5 - 10 - 50 - 250 km
What are the Ranking results?
Once you have selected your option, you will get the ranking results. These results are presented as follows:
1. Ranking of your street based on the average day count (by type of vehicle, here pedestrians (average number of registered vehicles on the abscissa, number of Telraams with the same average on the ordinate) :
On the left side of the screen you have an overview of the average number of pedestrians on your street (here 13) and a conclusion of the comparison with other streets. Here the result is "very high". Other conclusions could be: high, medium, low, very low.
On the right side of your screen, you have two tables:
1. Histogram:
In statistics, a histogram is a type of graph that shows the frequency distribution of data, usually in the form of vertical bars. This type of graph is also called a frequency histogram, and sometimes a bar graph. In a histogram, the height of each bar indicates the number of items in that range of the graph. Histograms in distribution graphs are often considered the most important tool for studying the distribution of data.
Here you can see that your street appears in red on the graph.
2. A barcode plot:
On this graph, the data for each of the streets included in the equation are sorted by size. Your street is again shown in red but you can see the results for other specific streets by moving your mouse over the graph.
You will of course get these data for all types of vehicles (pedestrians, cyclists, cars, large vehicles):
2. Speed results
Further on the screen, you can see the results of the equations related to the speed of vehicles (through the same type of presentation as above):
2.1. The V-85 data (To learn more about the V-85, click here):
On the histogram (top graph in blue), you will find the average speeds recorded on the x-axis (horizontal) and the number of Telraam-devices that recorded this average speed on the y-axis (vertical).
2.2. Results by speed interval (30-50 km/h, 50-70 km/h, 70+ km/h):
On these histograms, you will find on the x-axis (horizontal) the percentage of vehicles recorded for the given speed interval and on the y-axis (vertical) the number of road segments that recorded the same percentage.
3. Modal split results
Here you get the percentage of registered vehicles by modality type (percentage on the x-axis, number of Telraams on the y-axis):
