October 10, 2017
Project ID: CTEDD-017-11
Author(s): Suyun Ham, University of Texas at Arlington
CTEDD Grant Cycle: 2017 General RFP
The research objectives of this project are the maintenance of transportation infrastructure: i) to develop and improve the reference-free crack measurement (RACM) hardware system for field applications, ii) to develop a post-processing diagnostic framework, iii) to develop monitoring system based on internet of things. In the research category, the reference-free crack measurement system is an innovative technique to improve system efficiency and better maintenance of existing infrastructure.

Evaluation of Pavement Performance Using Remote Sensing Techniques

October 10, 2017
Project ID: CTEDD 017-10
Author(s): Anand J. Puppala, University of Texas at Arlington
CTEDD Grant Cycle: 2017 General RFP
Annually, transportation agencies spend several millions of dollars of expenditures for their rehabilitation works due to the problematic soils underneath the infrastructure assets. The soils in Dallas-Fort Worth region have high tendency to undergo swell-shrink behavior that contributes to the premature failure of pavements. The proposed research focused on conducting the laboratory tests on the field collected samples and validating their field performance using innovative data collection technologies.

Overcoming Local Barriers to Regional Transportation: Understanding Transit System Fragmentation from an Institutionalist Framework

October 10, 2017
Project ID: CTEDD 017-08

CTEDD Grant Cycle: 2017 General RFP
While the federal government spends billions on transit projects each year, many regions have poor coordination of services, with some regions having over 21 transit agencies failing to offer integrated schedules, fares and services, while other regions have large swaths that are completely unserved. Many of these inefficiencies are not due to a lack of technology or funding, but to failing of the local funding and governmental structure.
