Point Evaluation

Point Evaluation lets you evaluate traffic data at specific count points. The evaluation compares intensities between an analysis period and a reference period and calculates KPI scores.

Evaluation overview

The page consists of:

1. Title bar: At the top, the title bar shows the project name and template name (separated by ·)
2. Configuration panel: Select periods and time windows
3. Map or KPI table: Shows point objects and KPI colours per time window
4. Charts: Daily patterns, time-window analyses, and comparisons

KPI calculation

The KPI is calculated as the percentage of intensity in the analysis period relative to the reference period.

Formula: KPI = (Analysis period average / Reference period average) × 100

Calculation process:

1. Daily pattern calculation:

   • For each object a daily pattern is calculated for both the analysis and reference period
   • The daily pattern contains for each time interval the average number of vehicles over all days in the period

2. Average calculation per time window:

   • Analysis period average: From all time intervals within the selected time window, the average (median) number of vehicles is calculated over all days in the analysis period
   • Reference period average: In the same way the average (median) is calculated for the reference period

3. KPI percentage per time window:

   • The KPI percentage is calculated per time window by dividing the analysis period average by the reference period average and multiplying by 100
   • If either average is missing, the KPI cannot be calculated and the colour score is grey

Example calculation:

• Analysis period: 1–7 January 2024
• Reference period: 1–7 January 2023
• Time window: 07:00 – 09:00 (morning peak)

Step 1: Daily pattern calculation

• Analysis period: Average per time interval over 7 days
• Reference period: Average per time interval over 7 days

Step 2: Average per time window

• Analysis period average (07:00–09:00): 1200 vehicles
• Reference period average (07:00–09:00): 1000 vehicles

Step 3: KPI calculation per time window

• KPI = (1200 / 1000) × 100 = 120%

Interpretation of KPI values:

• KPI = 100%: The intensity in the analysis period is exactly equal to the reference period
• KPI > 100%: The intensity is higher than the reference period (for example 120% means 20% more traffic)
• KPI < 100%: The intensity is lower than the reference period (for example 80% means 20% less traffic)

Colour coding:

• Green: KPI ≤ lower limit — Intensity is significantly lower than reference
• Blue: lower limit < KPI ≤ upper limit — Intensity is between the limits, comparable intensity
• Orange: KPI > upper limit — Intensity is higher than reference

Adjusting evaluation

An analysis and reference period are already preconfigured by the project owner. If more periods are configured, you can switch between them via the left configuration panel. That way other periods can be compared with each other for more insight.

Analysis period

Select the period you want to analyse:

• Choose from configured project periods
• Or use the button to configure a custom period (see below)
• The analysis period is used as the period under test for the evaluation

Reference period

Select the reference period for comparison:

• Choose from configured project periods
• Or use the button to configure a custom period (see below)
• The reference period serves as the reference for the KPI calculation

Configure custom period

1. Click the calendar button next to the period selection
2. Choose a static or dynamic period
3. Choose which days within this period are included (specific weekdays or the same weekday as the selected date)
4. Save the custom period

The custom period now appears as Custom in the dropdown menu. You can switch between the preconfigured periods and this custom period.

See period type for more information on setting up periods.

Timeslot selection

Select the time window you want to evaluate:

• Choose one of the configured time windows
• The time window determines which time window is analysed

KPI set selection

Select the KPI set you want to use for the evaluation:

• Choose one of the configured KPI sets
• The KPI set determines the limits (lower and upper limit) for the KPI colour score
• Each KPI set has its own limit values that determine when a KPI score is shown as green, blue, or orange
• You can switch between different KPI sets to view the evaluation with different limit values

Day selection

Select a specific day for additional functionality:

• Dynamic periods: When using a dynamic period, the selected day determines the reference point for the period calculation

• Chart comparison: The selected day is (optionally) additionally shown in the following charts:

  • Daily patterns (24 hours): The selected day is shown as an extra line, so you can compare a specific day with the averages of the analysis and reference period.
  • Vehicles per time window: The selected day is shown as an extra data point alongside the averages of the analysis and reference period.
  • Same weekday: The 6 weekdays in this chart are determined by the 5 same weekdays preceding the selected day (e.g. if you select Monday, all Mondays are compared).
  • Last 4 weeks: The days in this chart are determined by the 4 weeks preceding the selected day.

Open selection in Analysis

When the Analysis module is available for the project, the configuration panel shows the Open selection in Analysis button.

• First select a point object on the map or in the KPI table
• Click Open selection in Analysis to open Analysis in a new tab
• The linked measurement locations of the selected object are prefilled in the Analysis selection list
• The button is disabled when there is no suitable selection (for example when no object is selected yet, or for data that Analysis does not support)

See From Monitor or Evaluation for what happens in Analysis.

View results

The evaluation results based on the settings are made clear via the map, the KPI Table, and various charts. These are explained below.

Map view

The map shows:

• Point objects: Locations of the configured count points
• Colour coding: KPI scores displayed visually for the selected time window
• Popup: Hovering a point object shows the object name, selected time window, average intensity for the analysis and reference period, and the KPI ratio
• Selection: Click an object to view the charts for that object

KPI table

The KPI table shows for each point object:

• Object name: Name of the point object
• KPI score: Calculated score (colour and percentage) per time window based on the comparison
• Tooltip: A tooltip when hovering the colour score containing the average intensity for the relevant time window for the analysis and reference period

The table is sorted from high to low based on the KPI Score for the selected time window. By selecting a different time window the sorting can be adjusted.

Charts

Daily patterns (24 hours)

This chart shows the daily patterns for the selected object:

• Analysis period: Average intensity per time interval over all days in the analysis period
• Reference period: Average intensity per time interval over all days in the reference period
• (optional) Day (date): The data of the day selected in the configuration panel. This allows a specific day to be compared with the other periods. This line can be toggled on/off by clicking the day in the legend.
• Time window: A shaded area in the chart indicating the time window (unless Full day is selected)

Use this chart to identify patterns and see differences between periods.

Vehicles per timeslot

Shows the number of vehicles for each time window for the selected object:

• Total number of vehicles per time window for the average analysis period
• The same for the reference period
• (optional) Day (date): The data of the day selected in the configuration panel. This allows a specific day to be compared with the other periods. This can be toggled on/off by clicking the day in the legend.
• On the x-axis the KPI colour score per time window is shown. This corresponds to the scores in the KPI Table.

Vehicles within timeslot (tabs)

Two tabs with totals per time window:

1. Same weekday: Compares the selected time window for the same weekday (e.g. all Mondays) based on and ending on the selected day in the configuration panel. Days without data remain visible on the x-axis without a bar.
2. Last 4 weeks: Shows the last 4 calendar weeks for the selected time window ending on the selected day in the configuration panel. Days without data remain visible on the x-axis without a bar.
