- H2020 Project from 2020 to 2023
- Six living labs with different innovative logistics concepts
- Lyon, The Hague, Madrid, Budapest, Porto, Oslo
- One partner for implementation and one for research each
- Development of a generic modeling library for last-mile logistics scenario simulation and analysis
Lyon Living Lab
- Peninsula Confluence between Saône and Rhône
- Interesting use case as there are limited access points
- Implementation of an urban consolidation center (UCC) to collect the flow of goods and organize last-mile distribution
- using cargo-bikes
- using electric robots
- and others
- Analysis and modeling through
- Flow estimation through cameras
- Simulation of future scenarios
- Focus on parcel deliveries due to data availability
Modeling methodology
- Main question: What is the impact on traffic and population of implementing an Urban Consolidation Center in Confluence?

Iterative proportional fitting (IFP)
- Based on synthetic population, find average number of purchases delivered to a household defined by socioprofesional class, age of the reference person and household size per day.
\mu_{a,h,s} = d_{s} \cdot \frac{w_{a,h,s}}{365}

Maximum entropy approach
- We now the average number of parcels, but we do not now the distribution of the number of parcels for a household on an average day.
- We know it must be non-negative, and we know the mean.
- Without additional data, we assume maximum entropy distribution, which is Exponential in this case.
F(N \leq n) = \text{Pois}(\mu)

Minimization of a
Vehicle routing and fleet composition problem
to select among a class of vehicles and their routes
(Currently, simple heuristic approach)
Scaling up: City-wide baseline
- Allows us to cut out a better baseline scenario for Confluence
First main result: Estimate of the total distance driven for parcel deliveries in Lyon (by the most frequent operators).
Scaling up: City-wide baseline
Coming up: KPI Calculation
GHG/PM Emissions: Simulation based on Hbefa database with detailed driving conditions (cold start, current speed, ...)
(Alternative in LEAD: COPERT)
Noise Emissions: Simulation simulates noise emissions and emissions to arrive at exposure values
Coming up: Scenario dashboard
Caution: Current test results to exemplify the methodology. Model needs to be improved in multiple stages (see slide after).
