An MVP has been defined during the first quarter of 2022, the web version began by focusing on:
- Targeted at consulting firms helping cities (not countries)
- Focused on GHG estimation for BAU (First sheet, 1A)
- Focused on passengers (no freight)
With the following features:
- Select country/city and reference year
- Create used accounts to specify profile type, save and track data
- Proper presentation of the tool
- A welcome page, with description of the tool, its goals and its relation to MYC
- Compute GHG emissions (using the ASIF methodology) with the following parameters:
- Vehicules-kilometers travelled (vkt)
- Occupancy and average trip length per vehicle type
- Vkt per fuel type
- Average energy consumption and energy efficiency
- CO2 impact of electricity
- Improve the way data is filled
- Progress bar to track data collection journey
- Help in the choice of category of transport
- Guide users in their inputs
- Add a contact email or a way of reaching the MYC team
- Predict emissions increase based on economic and travel growth between now and 2050 if nothing is done (Business As Usual)
- Visualize output data as graphs
- Ease the understanding of computations
In 2023, the version MVP2 was released, complementing the scope to match the functionalities of the excel spreadsheet. The following features were included:
- Complete rework of the Inventory & BAU steps described in the first MVP. A project is now divided in three steps
- An inventory, focused only on the reference year. This is where vehicles and fuels are defined
- A Business as Usual (BAU) scenario, built on top of the inventory
- One or more Climate scenarios, to be compared to the BAU
- Each step includes a small results page, to identify potential problems in data
- Full rework of the User Interface
- Match the features of the latest version of the offline tool (excel)
- This includes an update on computation methods, filling option, new types of fuels such as hydrogen and an update of default emission factors
- Creation of an educational path based on the MYC guides and notes from the Excel tool, including:
- Explanatory and illustrated texts of various calculation methods
- Description of the required data for each step
- Detailed tooltips for each parameter
- Concise formulas for intermediate calculations
- Guidance on how data can be filled
- Addition of a source entry and management system for each data point
- Addition of a note-taking field on each page, providing a space to summarize assumptions and back-of-the-envelope calculations
- Unlike MVP1, the tool now supports the input of climate scenarios, with or without prior calculations
- Addition of a page for comparing different scenarios
- This page contains a set of configurable graphs, exportable as PNG images or CSV files
- It also includes a summary of the sources used in the project
- Finally, it allows for downloading all data entered into the tool in CSV format. This export facilitates the transition from the online tool to Excel if necessary
- Similar to MVP1, a project can be "validated", making it visible to other users
- Unlike MVP1, population and GDP data have been removed since they are not used in emissions calculations
2023 also includes the release of the version 2.1 - Community Edition, built with volunteer work from various contributors
- Redesign of the tool's introduction page, now more visually appealing
- Addition of new illustrations, icons, and a typeface in line with the MYC graphic design
- Significant work has been done to standardize all interface pages, accompanied by various visual enhancements
- For example, uniform cell sizes in tables and improved handling of text and number overflows have been implemented
- These improvements affect all visible pages, as well as dynamic elements like tooltips and popups
- In addition to numerous interface changes, a few bugs have been fixed:
- Added support for HTTPS for a more secure browsing experience
- Fixed a bug that prevented project creation under certain conditions
- Corrected an incorrect vkt calculation based on the order of inventory filling in "fleet" mode
- Fixed project deletion
- Branding
- Made MYC name & logo more visible
- Colorize partner logos
- UI
- Fix text being cut short on required information fields on introduction pages
- Fix invisible scrollbar on chrome (at least on unix)
- Fix scrolling when choosing between default vehicle categories in inventory
- UX
- Display well to wheel results by default on inventory results page
- Prevent users from adding special characters and letters in number fields, also convert commas to dot automatically.
- Design rework on the welcome page
- New feature: New vehicles and fuels can be added at the start of BAU & Climate scenarios, instead of having to go back to inventory and redoing all the steps
- This is done at the first step of both BAU & Climate, using the button "Click here to edit vehicles and fuels"
- Overall, the system is way more resilient to this kind of after-the-fact changes.
- New feature: Climate scenarios can now be deleted if more than one is present
