I'm very proud and happy that this work was the result of my master's degree.

I strongly believe that it is possible to implement new ways of evaluating changes in the transport network and redesigning/optimizing networks based on this new indicator.

Super glad to share we have a new paper out! I'm particularly excited & proud of this one for a few reasons: 🧵👇

O Gov federal anunciou hoje um pacote de R$ 10,6 bi para renovação de 5 mil ônibus, sendo ~ 2.500 ônibus elétricos. A intenção é boa, mas deve vai gerar um problemão em poucos anos. Por que? https://t.co/c25v5T18qc

Excited to have been involved in this paper. Take a look! :)

Chuffed to see our paper online. Here we intoduce the new time interval cumulative accessibility measure, which mitigates the impact of arbitrary choices of trip duration on cmltv accessibility analyses

This is one of the most exciting accessibility research projects I've been involved in recently.

Perhaps of interested to a few tweeps @papa_enrica @liuluyu0378 @ahmedelgeneidy @Ehab__Diab @humantransit @AlexKarner @turleyvoulgaris @trnsprtst @FarberSteven @KManaugh @yinglingfan

[João Lucas 🚎🚲🗺 @_jaolucs]

@humantransit @UrbanDemog That would be great! We are thinking a lot about applications of this indicator for network design. I particularly believe that this indicator can support network intervention decisions.

[João Lucas 🚎🚲🗺 @_jaolucs]

Excited to share the pre-print of the paper I wrote for my master's dissertation:
“A novel route-based accessibility measure and its association with transit ridership”, co-authored with Francisco Moraes and @UrbanDemog
Link: https://t.co/Q0yME9F8Uj
Thread (1/n):

[João Lucas 🚎🚲🗺 @_jaolucs]

Here's the link to the preprint again. https://t.co/Q0yME9F8Uj. Any feedback is much appreciated!

[João Lucas 🚎🚲🗺 @_jaolucs]

A robust route-based access metric could help practitioners incorporate accessibility analysis into transit system redesign projects & help them anticipate what accessibility impacts & subsequent changes in transit ridership could be expected from route-level service changes 13/n

[João Lucas 🚎🚲🗺 @_jaolucs]

The proposed route-based accessibility measure contributes to a growing body of literature that tries to understand the influence of accessibility on transit ridership. Moreover, it could help transport planners incorporate accessibility analysis into day-do-day practice 12/n

[João Lucas 🚎🚲🗺 @_jaolucs]

Our proposed indicator outperforms the others because it is the only one capable of capturing how the access conferred by a route results from its operational and connectivity characteristics, as well as the land use and population patterns along its path 11/n

[João Lucas 🚎🚲🗺 @_jaolucs]

In all tests, we find that the proposed indicator captures much stronger association btwn transit ridership & accessibility. This is regardless of using cumulative or gravity decay functions, or if we look separately for different types of transit routes (feeder, trunk) 10/n

[João Lucas 🚎🚲🗺 @_jaolucs]

Drawing on data from Fortaleza, we compare the proposed metric Vs two other route-based accessibility metrics from the literature. We examine how strong is the association btwn route-level ridership & these accessibility measures using correlation & multvar regression models 9/n

[João Lucas 🚎🚲🗺 @_jaolucs]

We then propose a Directed Acyclic Graph (DAG) mapping the causal paths of key variables that influence ridership at the route level, including accessibility & its components (land use, transportation, people). This informs how we model the association btwn access & ridership 8/n

[João Lucas 🚎🚲🗺 @_jaolucs]

If accessibility is one of the main benefits of transit systems, and if transit ridership reflects the direct utility people derive from transit services, we should expect that the accessibility provided by a transit route should be a good predictor of its passenger demand 7/n
