The on-time performance overlay helps users see the signal in the noise, compare areas, and guide smarter decisions. An hexbin map, also known as a hexagonal bin map, divides a spatial area into hexagons and uses colour to represent data aggregated within each hexagon.
By default, Early on time performance is selected (1). Toggle these chips on/off to allow you to quickly identify where the problems are in the network (early, late, not detected) so that a deeper exploration can start. Hover over hexbins to view a summary of performance for stops in that hexbin (2).
Please refer to the FAQs for more information on the categories of on time performance.
How OTP is visualised
-
OTP appears as hexbins on the map, coloured by their corresponding category (Red = Early; Green = On time; Orange = Late; Grey = Not detected)
-
Each hexbin contains a number of stops which determines the hexbin colour. Each hexbin is coloured by the predominant EOL* of the stops inside the hexbin.
-
Single and multiple selection of EOL chips, renders different colours.
-
When multiple EOL chips are selected, the map shows solid colours, each colour corresponding to the selected category.
-
When a single EOL chip is selected, the map shows a single colour dispersed through a range of values, from lighter colour representing lower numbers, to darker colour representing larger numbers.
-
*Please refer to the FAQs for more information on how EOL is defined.
Interactive Features
-
Hover over a hexbin: Get an instant pop-up showing key information, including:
-
Number of stops inside the hexbin.
-
Number of actual visits compared to the scheduled visits to the stops.
-
OTP bar showing the aggregation of all the stops' on-time performance percentages.
-
-
Click on a hexbin: Clicking on a hexbin opens a side panel (1), that provides a detailed breakdown of the on-time performance for all stops within that hexbin. This helps you move from high-level hotspot detection to stop-level diagnosis in just one click. The side panel includes:
-
Aggregated OTP bar for the selected hexbin, showing the overall percentage breakdown of Early, On time, Late and Not detected stop visits.
-
Scheduled vs. actual stop visits count, giving you visibility into data completeness and reliability.
-
A list of stops within the selected hexbin, sorted by the highest percentage of the dominant EOL category (e.g. sorted by Early %, if early is the leading issue
-
Additional Tips
-
You can filter the visualisation to a number of services (2). In this case, the hexbins will only be shown covering the stops used for the selected services.
