Highways England Condition Indicators
About the PIT Condition Indicator
Horizons combines condition parameters from survey data to calculate the HECI is calculated based on asset groups, weighted condition families, and thresholds. It outputs a score between 0 (Good Condition) and 240 (Very Poor Condition), classifying network sections into red, amber, and green bands to quickly identify lengths in poor condition.
Horizons also presents the severity of TRACS defects through the NPC Indicator. See About the Network Pavement Condition Indicator.
You can view the HECI output in Layers and Reports, and create Works Plan strategies to reduce the HECI red quantity over time. Horizons updates the HECI with each data refresh. See Viewing the HECI.
The following components combine to formulate the HECI:
- Asset Groups - Horizons first divides your network into asset groups. These fundamental road types define weighting tables to configure the HECI.
- Condition Families - survey condition parameters are divided into three condition families.
- Thresholds - parameters are measured against pre-configured rating curves, and classified into different thresholds.
See Components Used to Calculate the HECI and How PIT Calculates the HECI.
When Horizons encounters an asset with an unknown age, the HECI can be used to determine a notional age for asset valuation. The output of asset valuation is a report in Horizons detailing the Total Depreciated Replacement Cost (DRC) and Gross Replacement Cost (GRC) of the pavement asset.
