Roiko Y. Determination of reasonable street and road network formed by residential districts

The dissertation is dedicated to determination of the regularities of formation of street and road network depending on reasonable lengths of the residential district. For that purpose, mathematical model has been developed for determination of the optimal length of the street and road network section, which is a side of the residential district. The above provides for minimum costs for functioning of the passenger and cargo transport system during the performance of the whole scope of transportation. When determining the costs of passenger and cargo transport system were divided in two components, these are the costs related to transport and passenger flow movement. The range of variation of factors of mathematical model have been determined and their influence has been analyzed as a result of experimental research. It has been found that the length of the line of vehicles at the crossroad, time consumption by the cars in the flow when passing the crossroads, the vehicles speed have the most considerable influence among the parameters of transport flows and the number of passengers coming to the stop - among the parameters of passenger flows. The research of influence of the residential district side length relation on density of the transport network servicing the territory adjacent to the sides of the district has been performed. If has been found that where the area of the residential district is in the range 20 - 50 ha, the density of the transport network is in the range 3.0 - 5.0 km/km2. On the other hand, the research of the influence of the residential district side length relation when partitioning residential district allowed us to find its nonlinear dependence from the density of the transport network of residential districts and its (district's) dimensions.
