Towards transit data accessibility: Large language models and software tools for GTFS
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2027-05-01

Developing a new job accessibility measurement based on crowdsourced traffic data and GTFS
… by using the General Transit Feed Specification (GTFS) dataset. These computed data are used to estimate the utility-based travel impedance functions. Based on the utility-based travel impedance functions estimated by the binary logit choice model, this research refines a job accessibility …

A study of open payment fare systems : system design, fare engine algorithm and GTFS extension
… to the General Transit Feed Specification (GTFS), and develops a generic fare engine design that can be shared across multiple transit systems. These extended designs are studied and tested on the LIRR and Transport for London (TfL) networks. The proposed design appears to accommodate the …

The Role of Phosphorylation in Modulating PC4 Function as a General Cofactor
… devoid of other general transcription factors (GTFs) commonly copurified with TFIIH and RNA polymerase II by traditional approaches, are fully functional in mediating both basal and activated transcription, regardless of whether TBP or TFIID is used as the TATA-binding factor. Interestingly, …

Regulation of transcription in Plasmodium falciparum, the causative agent of severe malaria: initial characterisation of PfTBP and PfTFIIA
… RNAP-II and the general transcription factors (GTFs). Bioinformatics analyses show that the RNAP-II GTFs in P. falciparum have greatly diverged from those studied in other eukaryotes, suggesting the existence of parasite-specific gene regulatory mechanisms, which have so far not been studied. …

The Sumoylation of General Transcription Factors Regulates Transcription in Saccharomyces cerevisiae
… Out of the six general transcription factors (GTFs), we have determined that transcription factor IID (TFIID) and transcription factor IIF (TFIIF) are targets of sumoylation. The functional impacts of GTF sumoylation were assayed using strains with elevated or reduced TFIID or TFIIF …

Accessibility Impacts of Bus Access to Managed Lanes
… to General Transit Feed Specification (GTFS) data through the use of the StopTimesEditor computer program developed for the purpose of this analysis. The methodology is tested on two express bus routes in the Minneapolis - St. Paul region (Twin Cities). The change in operating speed …

Multi-modal public transport modelling under traffic disruptions
… integrating heterogeneous data sources such as GTFS, smart card and incident log data, our framework simulates spatial-temporal impacts of disruptions on traffic states, including delay, travel time, flow and density. Furthermore, a dynamic traffic assignment model captures adaptive mode and …

REGULATORY MECHANISMS OF TRANSCRIPTION AND ASSOCIATED DNA REPAIR
… work has revealed the extensive participation of GTFs in the process. Collectively, results of above studies provide a comprehensive view of transcription and associated process of active genome repair.

ELUCIDATION OF REGULATORY MECHANISMS OF TRANSCRIPTION AND COUPLED mRNA EXPORT
… Our results show that activator and GTFs (general transcription factors) are involved in antisense transcription initiation. However, antisense transcription is initiated independently of the sense transcription. Collectively, the outcomes of my thesis research provide important …

GENOME-WIDE PROTEIN MOLECULAR ARCHITECTURE OF HUMAN PROMOTERS
… that different general transcription factors (GTFs) exhibit specific ChIP exonuclease stop patterns at TATA boxes, which are precisely located 30 bp upstream of genome-wide transcription start sites (TSSs), irrespective of strand orientation. Furthermore, when RNA polymerase II (Pol II) …

Predicting Ridership and Travel Time Impacts of Bus Service Changes Using Sketch Planning Methods
… exporting a General Transit Feed Specification (GTFS) feed of a given bus network scenario, that agencies may have access to through existing transit planning tools. Direct demand models are developed to estimate bus ridership at the level of approximately one-mile route-segments and time-of-day …

Understanding Subway Vibrancy in Live-Work-Play: A Case Study from and for Santiago, Chile
… transactions in the city, and transit data in GTFS format, the results from the Differences-in-Difference model show that new subway infrastructure positively contributes to the number of openings of new amenities – be it in a subway neighborhood or in other neighborhood that benefits from …

Visualizing urban accessibility metrics for incremental bus rapid transit projects
… in the general transit feed specification (GTFS) format, this toolkit is applied to transit performance and accessibility for example projects in two contexts, Boston and Santiago de Chile. Focus groups with transit advocates and planners were conducted in these two settings to evaluate the …

Biomolecular condensation of intrinsically disordered regions in P. falciparum and H. sapiens transcription factors
… the role of the general transcription factors (GTFs) and has not investigated the phenomenon in non-model eukaryotes such as P. falciparum. Here we report on the biochemical purification and functional characterisation of an ensemble of TF-IDR fluorescent protein fusion constructs, using …

An Investigation Into The Role Of Cfia 3' End Processing Complex In The Termination And Initiation/reinitiation Of Transcription
… without a parallel decrease in the level of the GTFs suggested a role for Clp1 in reinitiation of transcription. Third, an increase in 5' initiated antisense divergent transcripts in the Clp1 mutant supports a role for the factor in providing directionality to the promoter-bound polymerase. To …

Data and Information as Our New Transport Infrastructure: An Exploration into How the Modern Transport System Is Being Shaped by Information Communication Technology
… Center of ridesourcing origins in five cities, GTFS data from transit agencies, and the American Community Survey, this study contrasts the supply of TNC ridesourcing and transit systems at different times of day against area demographic profiles to understand their potential geographic consumer …
