PT is a green replacement for driving, or is it? (a case for on-demand PT)

by saeidadliData visualisation, maps and graphs, Public Transport, Python December 23, 2022April 13, 2023No Comments

Abstract PT has been generally accepted as a green replacement for driving in many cities worldwide. While average GHG emissions for buses are much less than for driving, its distribution shows that some bus routes emit more GHG than cars. Exploring the spatial distribution of bus emissions is important because it can justify alternative PT, …

The main difference of transit accessibility is in its schedule. While travel time to/from transport and in-vehicle time is common between car and transit, the real test of freedom in transit relies on its spontaneity. Frequency has …

Fixing the reliability issue of public transport in Auckland: A short term solution.

by saeidadliData visualisation, maps and graphs, Public Transport, Python, Working Paper September 28, 2020February 8, 2023No Comments

Introduction Bus service, especially in busy urban areas, is facing the challenge to enhance its reliability. Studies have revealed that unreliability can seriously undermine the attractiveness of bus service (Lin et al., 2008). Hence, most transit agencies have monitored service reliability as one of the key performance measures for their bus operations (Benn and Barton-Aschman, 1995). …
