August 2011 Navigating the Enterprise: A Universal Need for Traffic Speeds and Travel Times By Nick Cohn A Universal Need for Traffic Speeds and Travel Times June 2011 Drawing a New Generation of Surveyors By Don Talend for Enterprise GIS By Ross Smith and Rupen Mehta 26 ountries and people worldwide are affected by increasing car ownership and traffic vol- umes, which lead to increasingly intensifying congestion problems on the global road network. In the world of business, traffic congestion is responsible for the loss of billions in productivity. Its impact on the environment, in terms of additional CO2 emissions and increased fuel consumption, also is huge. The traffic congestion issue isn't a secret. There are more cars and more demand than road capacity, but traffic congestion can't be solved by just building more roads. And although there have been attempts to help reduce cars on the road, better use of the existing road network must be part of the solution. Because traffic congestion has a negative impact on the economy and environment, the topic is being given a high profile for attention at relevant regional and national government agencies. Addressing the causes is time consuming and expensive; detailed and reliable decision-making support tools are required so experts and policymakers can make timely and GEO W ORLD / AUGUST 2O11 cost-effective decisions that lead to positive changes to local traffic-management programs.

In addition to government organizations, traffic data also are valuable for commercial organizations. Property developers, market-research firms, outdoor advertising agencies, planning and engineering firms, and others always are in search of reliable information about what's happening on the road network.

According to a professor who teaches land- surveying skills as part of broader curricula there, the ongoing infusion of technology into the field is what currently generates so much interest—from him and students alike. Like many universities, UT Knoxville has expanded its agricultural engineering curriculum. According to Robert S. Freeland, agricultural engineering professor in 6/14/2011 11:04:41 AM Education
