The article presents the local type of logistic centers in urban environment as an essential part of freight network and its place in hierarchic logistic system of a country. Transport, compositional, ecologic and other aspects that have impact on spacial concept of local logistic centers are under examination. Thus generalized models of local logistic centers are put forward. They are developed by the authors with large volume of handled cargo, turnover capacity, and are space-saving. The main concepts of such models are following: vertical development of storage volume due to construction of several floor and shelf storage levels with different ramps as well as provision of comfort one-way transport of minimum maneuvers and without crossing and conflicting traffic.

Regression models for evaluation of terminal operations and traffic flow on adjacent road network are defined. By means of microsimulation, the processing time for each vehicle at the each gate set limits the maximum values of the input rate, which causes the average queue length not exceeding the value of 2.5 car.

The model of increase of efficiency of the created system of transportation of a municipal waste is presented. Need for carrying out modeling and the actions connected with reorganization of system, because of possible increase in total expenses is proved at shift of positions of reloading stations of rather optimum points owing to local conditions of the territory of municipality.
Keywords: a solid municipal waste, technological process of transportation, two - stage transportation
In this article the issues of determination of optimal parameters of transport and storage facilities are overviewed. It is stated that in some cases the incoming to the storage production volumes and the volumes of transportation vehicles are stochastic. That means that the problem of determination of facilities’ parameters by analysis is impossible without correctness’ losses. In similar cases it is proposed to use the so called “Monte-Carlo” method. In case of impossibility to describe analytically the internal processes, the range of the main phases of complex-system functioning modeling is given. To confirm the advisability of use statistical tests’ method for modeling of transport and storage facilities functioning, the results of coal mines loading facilities functioning researches.

In article the technique of optimization of placement of waste reloading stations, allowing to define both location, and number of stations that allows to reduce both operational and capital expenditure for the organization and functioning of system of the address with a waste is offered.

The article examines the relationship between tariffs and passenger demand. Proposed to use the algorithm for calculating the rate, which takes into account: the cost of the population for urban passenger transport, household income, the ceiling rate. Thus, we can calculate the tariff level above which a negative impact on the social condition of the population. This will solve the problem of affordability of urban transport for most of the population.
