When viewing the results of the analysis taking into account changes in public transport linked to the development of the Grand Paris Express (GPE), the application is based on the data made available by the Société du Grand Paris up to the following horizons : 2025, 2030

Thus, when you choose to display the results including the GPE, your employees' journeys by public transport will take into account the following future facts:

• Your employee will live (at his/her current address) close to an GPE station by the selected deadline.
• Its current site will be close to a GPE station by the selected deadline.
• One or more of the landing sites under consideration will be in the vicinity of an GPE station by the selected deadline.
• The routes will use sections that will open by the selected deadline as part of the GPE.

You can find details of the lines and stations concerned on the following sites:

• The interactive map of the Société du Grand Paris website
• The page of data.gouv.fr dedicated to Société du Grand Paris

NB: our data provider for this additional analysis remains TravelTime via their interface Traveltime Search, thus guaranteeing the homogeneity of our calculation approach.

Mode of transport optimizing time: The application proposes the vision of the indicators of the accessibility map and the distribution analyzes by not taking into account the mode of transport imported into the file by the customer, but by calculating the travel time for each of the three modes and in retaining the best of the three.

The difference in optimised mode is calculated by taking the optimised mode of the offer and comparing the travel time to the offer and to the current site, taking this mode into account.

Critical case: An employee is considered a critical case of accessibility for a site if it meets the two following criteria at the same time ...

• its travel time is greater than 60 minutes and
• its travel time increases by more than 20 minutes compared to the current site.

... or if one or more of the following conditions are relevant to its trip:

• its travel time is greater than 180 minutes and / or
• its cumulative pedestrian travel time is greater than 45 minutes and / or
• its cycling travel time¹ is greater than 60 minutes.

Not significant: A collaborator is considered insignificant and excluded from the calculation of your employees commute time analysis if his travel time to go to the current site is greater than 180 minutes and / or involves a cumulative pedestrian walk greater than 45 minutes or a cycling time greater than 60 minutes.

Hardship index: This is a relative index for all buildings considered and all employees. For those who come by car or bike, the index is based on the ratio between time and distance traveled. For those who come by public transport, this is the average of a time-distance index traveled and an index linked to the number of route connections².

Number of correspondences: For employees using public transport, it is the number of times they go from one transport to another, whether it is a change of line or a change of mode of transport.

Telework: The average (time, distance, carbon footprint, hardship index...) calculated when the telework option is selected, is weighted by the number of days worked on site for each employee.

¹ Does not take into account the electric bike.

The table takes into account current data

The CO2 emission of each employee's journey is therefore the sum of the calculations:

Distance travelled x CO2 emission per kilometre for each means of transport used to reach the destination.

The CO2 emission of the journey from the current site/offer:

Without the telework option : is therefore the sum of all CO2 emissions from the journey of all employees.

With the telework option : is the sum of the CO2 emissions of each employee's journey in proportion to their presence on site.

NB: Our data provider for the CO2 emission per kilometre for each means of transport is MOBIGIS.
