Extensive work is also expected to create additional disturbances and challenges and hence there is a need to create a balance.The main environmental aspects considered in this report include geology and soils, surface and groundwater conditions, air quality issues, generated noise, flora and fauna, landscaping and visual impact, cultural heritage, as well the population and general economy (OFlaherty, 2002, p. 123). This basically involves identification of the environmentally sensitive aspect along the connection route.
It should be noted that no biodiversity areas under national or international legislation protection have been identified as lying along the area of construction. However, usage of natural resources including water resources, agriculturally viable land as well as forests are reviewed in the report.The movement of traffic flow at intersections to specified lanes and paths, by way of traffic marks, is referred to as channelization. Channelization works for segregation of conflicts, regulation of conflict angles, regulation of speed, securing of automotive leaving or crossing the major traffic streams, securing of pedestrians, getting rid of excessive intersectional areas, blocking of prohibited movements as well as positioning of traffic regulation devices (Silver & Corbin, 2008).
The design speed at the intersection will help in governing multiple elements including entry-exit radius as well as the inscribed diameter. The design speed at the intersections, in this case, will vary from 20kmph to 25kmph.The radius at entry is defined by the design speed adopted, superelevation as well as the coefficient of friction. The radius should amount to drivers reducing their speeds to the design speed limit of the rotary. A range lying between 15 and 25 m is considered appropriate for the junction in question.
The exit radii should exceed the entry radii in order to enable the vehicles to increase speed while getting off the intersection.
