“…Macroscopic models assess vehicle traffic at a high level of aggregation as traffic flow (the number of vehicles passing a given point in an hour) without focussing on its components (vehicles) [124]. Microscopic models describe the behaviour of the units that make up the traffic stream, as well as the interactions that occur between them [125]. Mesoscopic models, on the other hand, are characterised by an intermediate level of detail.…”

Accurate estimation of vehicle emissions is essential and can be helpful in the decision-making process. Thanks to calculation methods, it is possible to accurately estimate the emissions that result from driving a car and to determine their impact on, for example, the health of pedestrians who are on the pavement near an arterial road. Recent years have seen an increase in the use and importance of emission models, as well as vehicle traffic simulation models. Increasingly, emission models are being combined with traffic simulation models, as it is not practical to actually measure the on-road emissions of an entire fleet of vehicles over a given stretch of road. This paper provides an overview of the selected work on the topic of emission modelling and vehicle traffic simulation models. The models are distinguished according to their respective scales of accuracy, i.e., micro, meso, and macro. Selected work combining emission and traffic simulation models is also presented, as well as development trends in the field. In particular, the paper also highlights the fact of proper calibration of vehicle traffic simulation models in order to obtain the most reliable vehicle emissions results from computational models. The review of the works carried out may be helpful for future projects concerning the use of simulation tools for transport and environmental decision-makers in the area of arterial roads.

The paper focuses on the specific dynamics between pedestrians and road vehicles observed at the public transport nodes. The emphasis is on the organization of traffic flows in terminals or locations with interchange stops. There are specific situations that occur in such cases as increased pedestrians' demand for crossing by bus arrival or change of periods with rush and low traffic (in the case of almost collective arrival or departure of more buses to/from a node). The study is conceived as a pilot study; emphasis is therefore put on the definition of a set of such situations and on the assessment of the basic attributes influencing them. This is also the reason why the study deals with only a limited number of public transport nodes; crucial is the design of the nodes and their functional links. This study aims to define these interactions and provide an input framework that allows modeling/simulating the mentioned situations. Stochastic models will be developed on two levels -level of microsimulation using PTV Vissim and mesoscopic simulation represented by own designed model using Visual Basic for Applications and dedicated especially to testing of newly modeled situations.

In this study, the Transit Network Design Problem (TNDP) is studied to determine the set of routes and frequency on each route for public transportation systems. To ensure the important concerns of planners like route length, route configuration, demand satisfaction, and attractiveness of the transit routes, the TNDP is solved to generate a set of routes by proposing an initial route set generation (IRSG) procedure embedded into the NSGA-II algorithm. The proposed IRSG algorithm aims to produce high-quality initial route set solutions to reach better optimization procedures. Moreover, the Multi-Objective Mixed-Integer Non-Linear Programming (MOMINLP) model is proposed to formulate the frequency setting problem on each route by minimizing the total travel time of passengers (user costs) and operator costs simultaneously, while maximizing the service coverage area near all the bus stops. The MOMINLP model is solved by applying the NSGA-II algorithm to produce a Pareto front between the first and the second objective functions. The model was applied to the Fargo-Moorhead Area (FMA), a small urban area. Results were compared with the existing transit network to measure the efficiency of the NSGA-II solution methodology. The proposed algorithm was found to considerably decrease the total travel time of passengers.
