You are requested to design a local road system in a residential area located in a mountainous terrain in New Nablus Suburban area. Area is restricted but need to have two traffic lanes and a parking lane in addition to the sidewalks. -Specify the design criteria for values of design speed, min and max. grades, min. radius, superelevation, cross slope, and sight distance. - What is the minimal and preferred dimensions for the cross section elements? -Specify the right of way and the dimensions and distribution of the elements you propose within the ROW. Draw your design. - If some of the roads are designed as cul-de-sac roads, suggest two design alternatives (one circular and the other rectangular) with proper design. Draw your design. 2. A collector road located in a rural area with rolling nature is to be rehabilitated. A new design will be prepared. Current volumes reach an ADT of 1460 vpd, and there exists two lanes. Traffic is expected to increase by 3% per year for the design period of 20 years. To perform design you are requested to do the following: - Recommend the min. and our preferred design speeds. - Design the crest and sag vertical curves for cases of max. upward grade followed by min. downward design for the crest curve and vice versa crest and sag curve. - Determine the width of the major elements comprising the ROW. What ROW do you recommend if the cross section lies in a cut rocky section with height of cut of 4 m. -Draw your design of the dimensioned cross section.
