Electric vehicle (EV) has become a potential traffic tool, which has attracted researchers to explore various traffic phenomena caused by EV (e.g. congestion, electricity consumption, etc.). In this paper, we study the energy consumption (including the fuel consumption and the electricity consumption) and emissions of heterogeneous traffic flow (that consists of the traditional vehicle (TV) and EV) under three traffic situations (i.e. uniform flow, shock and rarefaction waves, and a small perturbation) from the perspective of macro traffic flow. The numerical results show that the proportion of electric vehicular flow has great effects on the TV’s fuel consumption and emissions and the EV’s electricity consumption, i.e. the fuel consumption and emissions decrease while the electricity consumption increases with the increase of the proportion of electric vehicular flow. The results can help us better understand the energy consumption and emissions of the heterogeneous traffic flow consisting of TV and EV.

This paper firstly analyzed the current situation of integrated passenger transportation hub, putting forward the integrated passenger transportation hub had a strong advantage on developing green low-carbon economy. And then based on the energy consumption analysis of integrated passenger transportation hub, energy saving and emission reduction management measures were proposed.

Based on the NS model, an extended cellular automaton model is proposed to simulate complex characteristics and energy consumption of traffic flow with some slowdown sections on a highway by considering the number, speed limit and distribution of slowdown sections. The simulation results show that the present model can exhibit a multi-phase coexistence phenomenon, i.e., the freely moving phase, the maximum flow phase and the jamming phase coexist in traffic system. The fundamental diagram shows that the number of slowdown section has no influence on the mean velocity and flow. However, energy consumption increases with increase of the number of slowdown section at low density. In addition, it can be found that the speed limit and distribution of different slowdown sections have an important effect on traffic flow and energy consumption, and the underlying mechanism is also analyzed.

The article is devoted to solving scientific and applied problems of determining the rational location of stopping points at the entrance or exit from controlled intersections. Analysis of approaches and methods to the determination of rational location of stopping points showed that they are mostly based on the goals of minimizing the time for passenger transportation or maximizing the performance of transport systems functioning. With that, the question of determining the time of delay of vehicle departure from the stopping point bottleneck after the embarkation and disembarkation of passengers is paid very little attention to. Currently, there are only regression models available that cannot claim to be universal and their use in transport planning requires similar conditions of functioning with the object, where statistic data were collected. The conducted analysis allowed determining the trend of basic research, namely, assessment of the influence of traffic flow parameters on the delay time of route transport departure from the stopping point bottleneck in the area adjacent to the controlled intersection. The process of delay occurrence at the exit of route transport from the stopping point bottleneck was formalized as the object of study thanks to which there was built an analytical model to determine the time of delay of route transport departure from the stopping point bottleneck. There were investigated two options for placement of a stopping point at the entrance and exit from the intersection. According to the results of calculations, it was determined that the delay time of route transport departure from the stopping point was influenced by many factors, whose influence varies depending on the location of the stopping point at the entrance and exit from a controlled intersection. By the results of researches one can be affirm that the most expedient is the placement of a stopping point at the minimum acceptable distance from the intersection, and it is recommended to locate a stopping point at a distance of 30 m at the entrance to the intersection. Keywords: stop, route vehicles, traffic flow, regulated intersections, traffic, latency, capacity transport areas.
