The data on the traffic flow assessment on Marmion Avenue is as shown above as well as the
one included in the appendix section. The data is illustrative of the flow of vehicles, pedestrians
and the analysis of such flows on an hourly basis. Based on the analysis conducted, a
recommendation is made that the design of the proposed road be to the very standard as the one
used for Marmion Avenue including the traffic speed limit of 60 kph (Jamson, Hibberd & Merat,
2015). The proposed road should provide for pedestrian and vehicle movement in a manner that
is not only harmonious but also safe for use. The proposal below illustrates a 3 lane dual carried

ultimate configuration that may provide on idea on how the design of the proposal can be made.
The minimum width of each of the lanes should be 3 meters with the entire road width being
kept at about 8.5 m to ensure effective flow of traffic. Going by the traffic assessment, it can be
noted that there is serious traffic flow as well as movement of cyclists and pedestrians in the
morning as well evening hours most probably since such are the times when the employed
population is attending for and leaving their offices after work respectively (Visser, Brown &
Tinnelly, 2017). The design should be done in such a way that the huge traffic flow in the rush
hours is effectively taken care of with the various minimal speeds provided at various levels and
points on the road.
