Your assessment


To start with your assessment you will first have to provide some information about your project or scenario.
This will include defining if your project is on cycling, walking or both, which time and geophraphic scale should be applied, if you wish to assess one specific situation or compare two cases and which impacts you wish to assess.
This information will determine your specific "use case" and the related methodology and assumptions that the tool applies for your assessment.

Active travel modes

You can assess the impacts of walking, cycling, or both.
*Required field.

Geographic scale

*Required field.

Comparison and time scale

In a "single case" assessment, you only provide data on the so called "reference case". This is then compared to a hypothetical scenario of "no walking or cycling".
In a "two case" assessment you have to provide data on both cases, the so called "reference case" and the "comparison case." Typical examples are "before and after" an intervention, or comparisons of alternative "scenarios A and B".
In a single case assessment, by default impacts are calculated for 10 year. In a two case comparison, by default impacts are calculated for the time difference between your reference and comparison case. If you would like to assess benefits for a different number of years, specify it below (e.g. 10 or 30).


Motorized modes

If you do not have data for motorized travel modes, the assessment will be based on default values. If you have data on motorized modes in more refined categories, select "refined" (this will improve the accuracy of calculated impacts).

Data input

Introduction to data inputs

To enter your data on travel modes you will have to specify the unit, the actual amount, and the type of population it applies to.
The amount must be per person and day.
The population data (age range and number of subjects) typically refers to the general population - but you can specify whether your data refers to cyclists or pedestrians only (e.g. from automated counters).

If you specified earlier to compare two cases you will have to provide two sets of inputs for each selected mode (one for each comparison case).

Volume data active modes

To enter your data on the active travel modes selected earlier, please choose your unit, provide the actual amount and the type of population it applies to.
*Required fields

Volume data motorized modes

To enter your data on the motorized travel modes choose your unit, provide the actual amount, and the type of population it applies to.
*Required fields

Population data

The impact calculation by default excludes children and elderly because the underlying evidence and assumptions are not adequate for these age groups. Older persons benefit more from the same amount of active travel due to their higher mortality risk. If the walking or cycling assessed is predominantely done by younger or older subjects, select the age range accordingly.
The population figure must correspond to the population type selected before, i.e. the general population or cyclists or pedestrians only. The population figure should reflect the "total population" and not just the size of a study sample that may have been surveyed to derive volume estimates. In national and city level assessments this is the respective number of inhabitants, or the total number of cyclists or pedestrians. These figures need to be adjusted to the age range assessed (e.g. exlude children).

Data adjustment

Introduction to data adjustment

Now you will be asked to provide additional information on the active mode(s) that you are assessing. Answer each question for the mode(s) listed.
This information is needed to adjust your data for the selected impact calculations.

General adjustments

Proportion excluded
Exclude walking or cycling due to factors unrelated to your assessed intervention or scenario here.
Temporal & spatial adjustment
Adjust your data as necessary to reflect longterm averages.
Take-up time for travel demand
Specify how many years it takes until maximum volume of active travel is reached.

Contrast characteristics

Proportion of new trips
What proportion is due to entirely new trips?
Proportion of reassigned trips
Exclude walking or cycling trips that previously used a different route.
Proportion for transport
What proportion is for transport (vs. recreation)?
Proportion shifted from walking
Proportion shifted from cycling
Proportion shifted from running
Proportion shifted from e-biking
Proportion shifted from bike sharing
Proportion shifted from driving
Proportion shifted from public transport
Proportion shifted from car (as driver)
Proportion shifted from car (as passenger)
Proportion shifted from motorcycle
Proportion shifted from local bus
Proportion shifted from light rail
Proportion shifted from train

Other adjustments

Proportion “in traffic”
What proportion takes place in traffic (vs. away from major roads, in parks etc.)?
Traffic conditions
What are the local traffic conditions?
Change in crash risk
Would you like to specify a change in crash risk between the reference and the counterfactual case?
Substitution of physical activity
Is some of the active travel (in the reference case) replacing other forms of physical activity?

Investment costs

Investment costs
To calculate a benefit-cost ratio, provide a cost estimate for investments that led to the assessed active travel (in Euros).

Parameter review

Introduction to parameter review

In this section you can review all parameters used for your assessment. If you would like, you can edit default values to better reflect your local settings. The tool also uses background values which are cannot be changed.

Calculation parameters

The table below provides an overview of the default values used for your assessment. If you would like to use other values, you can edit column "Editable value".
The table below shows the background values that the tool uses for your assessment. These cannot be modified.


Introduction to results

HEAT provides several options for results viewing. On the next page you will see the overall results, or “grand totals”. These sum up the impacts for all active modes and all impact pathways assessed combined. Thereafter you have the option to select, which detailed results displays you would like to see. Results can be summed up by active modes and by pathways, or both.
