Learning Outcomes: | Upon successful completion of this course, an attendee will be able to:
-Understand traffic concepts required for highway design, including AADT, Peak Hour Factors, heavy vehicle percentages and Level of Service. Also understand Maintenance and Protection of Traffic parameters.
-Understand advanced Coordinate Geometry and Surveying concepts
-Gain familiarity with PennDOT’s standard typical sections, and basic roadway and roadside elements, including pavement, median, shoulders, curbing, clear zones, roadside barrier, and side slopes.
-Understand Horizontal Alignment and Superelevation features including circular curve layout, spiral curve selection, horizontal sight distance calculation, and traveled way determination.
-Understand Vertical Alignment features.
-Incorporating geometric and MPT requirements into drainage design
-Designing typical and innovative intersections and interchanges, including
Auxiliary Lanes, Diverging Diamonds, Displaced Left Turn, U-turn Intersections, Continuous T intersections, and Roundabouts
-Incorporating other elements affecting geometric design including Community Context,“Placemaking,”“Flexible Design,” Public Involvement, sidewalk criteria, 3-R Criteria, and ADA considerations
-Identification of key highway design elements in DM-2 and the AASHTO Green Book
