This paper reports the results of a study on developing level of service indices for evaluating urban transportation systems. For this purpose the travel choices of individuals are analyzed considering the effect of the transportation system characteristics on the system's level of service as perceived by the user. A utility maximization approach is used to yield a utility function that contains a new behavioural measure of accessibility. This function is considered as a level of service index that reflects the marginal benefits to a system's user when he makes a trip by the system.The parameters of the level of service indices are determined by using a sample consisting of 2695 trips obtained from the 1976 work trip survey for the City of Calgary, Alberta, Canada. Level of service indices are developed for four modes: auto driver, auto passenger, conventional bus, and express bus.The implementation procedure of the indices for assessment and evaluation is shown by a case study for the City of Calgary.

AbstractThe rapid development of economics requires highly efficient and environment-friendly urban transportation systems. Such requirement presents challenges in sustainable urban transportation. The analysis and understanding of transportation-related behaviors provide one approach to dealing with complicated transportation activities. In this study, the management of traffic systems is divided into four levels with a structural and systematic perspective. Then, several special cases from the perspective of behavior, including purchasing behaviors toward new energy vehicles, choice behaviors toward green travel, and behavioral reactions toward transportation demand management policies, are investigated. Several management suggestions are proposed for transportation authorities to improve sustainable traffic management.

Subject. We consider the economic relations that arise in the process of formation and implementation of the regional tax policy. Objectives. The purpose is to analyze the regional tax policy considering the Republic of Dagestan as a case study. Methods. The study employs methods of statistical, economic and mathematical, and systems analysis. Results. We propose measures that may be implemented in the system of tax policy of the Republic of Dagestan and contribute to its improvement in conditions of financial instability. Nevertheless, these proposals require further attention, a deeper level of design and development of testing scheme. They may also be used to study the tax policy of the region. Conclusions. The comprehensive analysis shows that the tax policy and other approaches to the regulation of the economic life of the country have advantages and disadvantages. It is obvious that the application of these tools may have a positive impact on the economy.
