Transcript of "Sun, Wind, Water, Earth, Life, Living: 3a traffic"

  1. 1. Sun wind water traffic earth life living, legends for design AR2U070 Territory (design) 5ECTSAR0112 Civil engineering for dummies (calculations) 2ECTS Prof.dr.ir. Taeke M. de Jong Prof.dr.ir. C. van den Akker Ir. D. de Bruin Drs. M.J. Moens Prof.dr.ir. C.M. Steenbergen Ir. M.W.M. van den Toorn
  2. 2. Wet networks
  3. 3. Distance between trenchesThe necessary distance L between smallest ditches or drain pipesis determined by precipation q [m/24h], the maximally acceptedheight h [m] of ground water above drainage basis between drainsand by soil characteristics. Soil is characterised by its permeabilityk [m/24h]. A simple formula is L=2√(2kh/q).
  4. 4. Calculating the distance

  34. 34. Measures in traffic Design measures are deduced from the dispersion of actual measures.Normally the 5% largest measures are left aside for design (95 percentile). Dispersion of real car Dispersion of the width of widths in 2004; parking places in 1980; 95 95 percentile is 1.80m percentile is 2.50m

  67. 67. Buchanan (1963)A hexagonal pattern (Figure 12) is very efficient, with economical three-wayintersections, but other polygonal patterns are possible. A rectangular patternrequires very complex intersections.…The function of the distributory network is to canalize the longer movements fromlocality to locality.…This means that they cannot also be used for giving direct access to buildings, oreven to minor roads serving the buildings, because the consequent frequentjunctions would be dangerous and make the road inefficient.It is therefore necessary to introduce the idea of a hierarchy of distributors,whereby important distributors feed down through distributors of lesser category tothe minor roads which give access to the buildings [13].The system may be likened to the trunk, limbs, branches, and finally the twigs(corresponding to the access roads) of a tree. Basically, however, there are onlytwo kinds of road - distributors designed for movement, and access roads to servethe buildings.
