Dedicated bus lane network design under demand diversion and dynamic traffic congestion: An aggregated network and continuous approximation model approach

Nikolaos Geroliminis, Mehmet Yildirimoglu

This paper proposes an integrated methodological framework to design a spatially heterogeneous bus route network and time-dependent service headways to serve travel demand that varies over time and space. Travelers choose to use either the transit mode or ...

Hierarchical Management of Heterogeneous Large-Scale Urban Networks via Path Assignment and Regional Route Guidance

Nikolaos Geroliminis, Mehmet Yildirimoglu, Isik Ilber Sirmatel

High level of detail renders microscopic traffic models impractical for control purposes and local control schemes cannot coordinate actions over the whole city. Thus, development of efficient modeling and control methods for large-scale urban road network ...

Investigating empirical implications of hysteresis in day-to-day travel time variability

Nikolaos Geroliminis, Mehmet Yildirimoglu, Ypatia Stefania Limniati

Day-to-day travel time variability plays a significant role in travel time reliability. Nowadays, travelers not only seek to minimize their travel time on average, but also value its variation. The variation in the mean and the variance of travel time (acr ...

Traffic modeling, forecasting and assignment in large-scale networks

Mehmet Yildirimoglu

Today, the development and evaluation of traffic management strategies heavily relies on microscopic traffic simulation models. In case detailed input (i.e. od matrix, signal timings, etc.) is extracted and incorporated in these simulators, they can provid ...

Multiple Concentric Gating Traffic Control in Large-Scale Urban Networks

Nikolaos Geroliminis, Mehdi Keyvan Ekbatani, Mehmet Yildirimoglu

A new gating strategy for concentric cities based on the notion of the macroscopic or network fundamental diagram and the feedback-based gating concept is introduced and successfully tested. Different regions of large-scale urban networks may experience co ...
