Maximizing space-time accessibility in multi-modal transit networks: an activity-based approach

Abstract

Maximizing space-time accessibility in multi-modal transit networks: an activity-based approachOver the past decades, the impact of transport operating strategy improvements on space-time accessibility, which is an important research area for network design problem, has not been explicitly investigated particularly with the use of activity-based approach. In this paper, a novel activity-based space-time accessibility measure is introduced for considering individuals' accessibility to various activities and travels in a unified super-network framework. A bi-level programming model is proposed for optimizing time-dependent transit line headways and fares in a multi-modal transit network from the activity-based space-time accessibility perspective. In the upper level, transit line headways and fares are optimized by time of day to maximize the network-wide activity-based space-time accessibility. At the lower level, an activity-based network equilibrium model is adapted to provide the resultant activity-travel patterns as reactions to the upper level decision. A simplified network in Hong Kong selected area is used to illustrate the application of the proposed model.

Bimodal transit design with heterogeneous demand elasticity under different fare structures

“…Third, the research emphasises rail, BRT, and ordinary bus transit modes, while there are other different ones. In the future study, some potential extensions could be explored, including (i) inclusion of personalized and customized transit mode in the joint design (Nuzzolo and Lam, 2017;Daganzo and Ouyang, 2019;Guo et al, 2019;Jiang and Ceder, 2021;Dou et al, 2021); (ii) investigation of the interrelations between bimodal transit design and other fare structures, e.g., time differentiated fares, discount fares, and special fares for particular passenger groups (Tang et al, 2020;Fu et al, 2020;Guo and Szeto, 2020); (iii) consideration of a polycentric network topology (Park et al, 2020;Cats and Birch, 2021;Huai et al, 2021);…”

Assessing Travel Time Performance of Multimodal Transportation Systems Using Fuzzy-AHP: A Case Study of Bhopal City

“…The activity-based method looks at accessibility from a broader angle, which can help transportation planners and lawmakers make better choices. By planning for both land use and transportation together, we can make multi-modal transit networks that are more efficient, last longer, and are easier for everyone to use [31]. SteadieSeifi et al said that it has many benefits, such as being more efficient, lowering shipping costs, and being more environmentally friendly.…”

Understanding User Equilibrium States of Road Networks Using Big Trajectory Data

“…UE is widely used in various transport planning applications, such as transport network designs, disaster evacuating planning, etc. (Sheffi, 1985;Yang and Bell, 1998;Chen et al, 2012;Fu et al, 2022).…”
