There seemed to be no obstacle that they were not willing to partner on and help get the work done.&rdquo;<\/p>\n<h2>Traffic engineering lab<\/h2>\n<p>Econolite also made a generous donation to <abbr>UH<\/abbr> to develop an advanced traffic engineering lab in Holmes Hall. The lab will be equipped with the most advanced traffic control, management and detection devices as well as a modern video wall for data visualization. Ma said the system will be a game changer for the College of Engineering.<\/p>\n<p>&ldquo;It will create unprecedented opportunities in cutting-edge research in traffic mobility and safety, such as vehicle-infrastructure integration, connected vehicle system control, arterial-wide speed harmonization and more,&rdquo; Ma said. &ldquo;The lab will become a mini traffic management center that enables <abbr>UH<\/abbr> researchers to analyze traffic data in real time and help <abbr>HDOT<\/abbr> staff make necessary adjustments to optimize the performance of the traffic system.&rdquo;<\/p>\n<p><strong>Guohui Zhang<\/strong>, a civil engineering associate professor who teaches undergraduate and graduate courses in transportation engineering and a co-principal investigator of the research project commented, &ldquo;This lab will significantly enhance our education program in transportation engineering.
