Interstate highways encourage long distance trips.)Comfort – Involves the physical characteristics of vehicles and roadwaysConvenience – The ease of making trips and the ability of transport systems to accommodate all travel needsEconomy – Try to provide the best possible systems for the moneyEnvironmental compatibility – Provide sustainable transport systems8Ethical Aspects – traffic engineers deal with the public as well as engineering topicsBe honestAvoid “cutting corners”Avoid tailoring the results to please the clientAvoid manipulating dataKnow what’s in the analysis models and softwareEngineers Code of Ethics (example)9Responsibility & LiabilityWe deal with people and goods.Safety is the utmost importance in this profession. Tort liability – Public agencies may be sued for negligenceProvide for the public safety through positive programs, good practice, knowledge, and proper procedure.Avoid liability problems[Read the right column, page 2]101.4 Elements of traffic engineeringTraffic studies and characteristicsPerformance evaluationFacility designTraffic controlTraffic operationsTransportation systems managementIntegration of ITS technologies111.2 Transportation Systems and their Function“Transportation systems are a major component of the U.S. economy and have an enormous impact on the shape of the society and the efficiency of the economy in general.” (For year 2009 stats click the link.)http://www-fars.nhtsa.dot.gov/Main/index.aspxhttp://en.wikipedia.org/wiki/List_of_countries_by_traffic-related_death_ratehttp://en.wikipedia.org/wiki/List_of_countries_by_population1213Figure 1.1 Public Highway Mileage and Annual Vehicle-Miles Traveled in the United States, 1920–2007 (Source: Highway Statistics 2007, Federal Highway Administration, U.S. Department of Transportation, Washington DC, 2008, Table VMT 421.)141.2.1 The Nature of Transportation Demand“This circular, self-reinforcing characteristics of traffic demand creates a central dilemma: building additional transportation capacity invariably leads to incrementally increased travel demands.
