(Dec. 10, 2010)--A survey conducted for the City of San Antonio by Kimley-Horn Associates resulted in traffic signal timing adjustments and reduced travel times at eight intersections near the UTSA Main Campus.
Based on the final report released last summer, signal timing adjustments completed on UTSA Boulevard from Roadrunner Way to Valero Way resulted in travel time reductions up to 26 percent. The timing adjustments also will result in estimated collective savings of $400 per weekday or $100,000 annually, based on 1.2 average vehicle occupancy.
Surveys were done before and after the timing adjustments in morning peak, noon and evening peak periods analyzing eastbound and westbound traffic. UTSA Boulevard signal timing adjustments decreased travel time 11 percent during morning peak, 26 percent during the noon period and 6 percent during afternoon peak.
Based on the survey, traffic signal timing was optimized at eight intersections:
During the morning peak at the Babcock and Hausman intersections, overall travel times were reduced. During the morning peak, a 28-second travel-time increase in lighter westbound traffic was more than offset by a 75-second travel-time decrease in heavier eastbound traffic. Conversely, during the afternoon peak, a 40-second increase in westbound travel time was offset by a 74-second decrease in eastbound travel time.
Before the timing adjustments, the four intersections along UTSA Boulevard (not including the Babcock intersection) ran in coordinated (interconnected and sequenced) mode during morning and afternoon peaks on a 120-second cycle. The three intersections along Hausman also ran in coordinated mode in the same periods on a 140-second cycle. At all other times, however, those seven intersections ran in free mode. The Babcock and UTSA Boulevard intersection ran in free mode at all times. "Free mode" indicates a signal is timed, but also has demand sensors (push-to-walk buttons and pavement sensors) to activate light changes.
In consideration of the survey results, all eight intersections now are on free mode from approximately 6:15 p.m. to 7 a.m. on weekdays and 6:15 p.m. to noon on Saturday and Sunday. At peak times, timing is adjusted to facilitate faster traffic flow.
According to the study, traffic at the eight intersections is above roadway capacity with Babcock at Hausman designated the most critical area. The study recommends upgrading both roadways to two lanes per direction with either four-lane divided or five-lane undivided intersections.
As an interim measure, the study recommends adding left-turn lanes at three intersections (listed in priority order):

The annual Center for Innovation, Technology and Entrepreneurship (CITE) 100K Venture Competition and Exposition will be held on the Main Campus on Dec. 1. Twenty-eight teams from across the university will exhibit their project; six teams will compete for a prize pool of more than $100,000 in funding to launch their new venture / company. More than 650 students have participated in launching new technology ventures.

This concert features 50 community children performing music in the UTSA Downtown String Project Winter Concert. The children, led by UTSA music students studying to be music teachers, will join together in playing the Theme from Batman at their concert. The Batman of San Antonio, a local celebrity figure, will make an appearance at the concert. This event is free.

As touch screens and e-books demand more and more attention from both casual readers and scholars, many people say the handwriting is on the wall for the printed page.
At UTSA, the handwriting is on the wall for a library that doesn't have any printed books.
Since March 2010, the bookless library in the Applied Engineering and Technology Building has given UTSA students an innovative way to read, research and work with each other to solve problems.
With ultra-modern furniture and a décor featuring desktop computers, scanners and LCD screens, the AET Library is designed to engage students in an online format. But it also offers group study niches and study rooms with whiteboards and glass walls on which students can write. The space encourages teamwork, communications and problem solving for the next generation of scientists and professional engineers.
Did you know? The UTSA AET Library is the nation's first completely bookless library on a college or university campus. It served as a model for Bexar County's first-in-the-nation public bookless library system and one of its branches, the Dr. Ricardo Romo BiblioTech.
The University of Texas at San Antonio is dedicated to the advancement of knowledge through research and discovery, teaching and learning, community engagement and public service. As an institution of access and excellence, UTSA embraces multicultural traditions and serves as a center for intellectual and creative resources as well as a catalyst for socioeconomic development and the commercialization of intellectual property - for Texas, the nation and the world.
To be a premier public research university, providing access to educational excellence and preparing citizen leaders for the global environment.
We encourage an environment of dialogue and discovery, where integrity, excellence, inclusiveness, respect, collaboration and innovation are fostered.
