The traditional approach to mobile phone positioning is based on the assumption that the geographical location of a cell tower recorded in a Call Details Record (CDR) is a proxy for a device's location. A Voronoi tessellation is then constructed based on the entire network of cell towers and this tessellation is considered as a coordinate system, w...

In this paper we develop conditions for various types of stability in social networks governed by Imitation of Success principle. Considering so-called Prisoner’s Dilemma as the base of node-to-node game in the network we obtain well-known Hopfield neural network model. Asymptotic behavior of the original model and dynamic Hopfield model have a cer...

The partition of the Mobile Phone Network (MPN) service area into the cell towers' Voronoi polygons (VP) may serve as a coordinate system for representing the location of the mobile phone devices. This view is shared by numerous papers that exploit mobile phone data for studying human spatial mobility. We investigate the credibility of this view by...

The effectiveness of congestion charges and parking prices as monetary disincentives to reduce car traffic and alleviate congestion in highly demanded urban areas is investigated, focusing on Jerusalem's diverse and congested city center. A tailored MATSim agent-based simulation model was used to examine various payment scenarios and assess the con...

Parking occupancy in a delineated area is defined by three major parameters – the rate of car arrivals, the dwell time of already parked cars, and the willingness of drivers to continue their search for a vacant parking spot. We investigate a series of theoretical and numeric models, both deterministic and stochastic, that describe parking dynamics...

The partition of the Mobile Phone Network (MPN) service area into the cell towers' Voronoi polygons (VP) may serve as a coordinate system for representing the location of the mobile phone devices, as demonstrated by numerous papers that exploit mobile phone data for studying human spatial mobility. In these studies, the user is assumed to be locate...

Transportation Network Companies (TNC), like Uber, Lyft, and VIA, started their activities a decade ago with a far-reaching hope that Mobility-On-Demand (MOD) transportation services would decelerate or even stop the ever-growing congestion. However, it didn't happen; the negative incentives, like congestion charges and higher parking prices, seem...

By definition, the Mobility-as-a-Service (MaaS) system integrates transportation modes of very different flexibility - taxis, buses, light rail, ride-hailing. MaaS major unknown is the effectiveness of the ride-sharing modes. We employ a calibrated and validated MATSim multi-modal traffic model of the Jerusalem Metropolitan Area (JMA) to assess the...

Parking occupancy in the area is defined by three major parameters - the rate of cars arrivals, the dwell time of already parked cars, and the willingness of drivers who are searching but yet did not find a vacant parking spot, to continue their search. We investigate a series of theoretical and numeric models, deterministic and stochastic, that de...

This paper aims to improve existing results about using averaging method for analysis of dynamic systems on time scales. We obtain a more accurate estimate for proximity between solutions of original and averaged systems regarding $\Delta$-periodic and $\Delta$-quasiperiodic systems, which are introduced for the first time. To illustrate the applic...

The scheme of partial averaging of systems with small parameter on time scales was established. A proximity of solutions of given and partially averaged system of equations was proved under sufficiently general conditions. Obtained results extend an application area for previously developed numerically-asymptotic method of solution for optimal cont...

Control systems with a small parameter on the time scale, as well as optimal control problems with terminal and vector quality criteria, are considered. The justification of the averaging method on the asymptotically large period of time and the matching algorithm of the controls of the original and averaged systems are presented for these systems....

A numerical-asymptotic method for the solution of the problem of optimal control over the system on time scales is substantiated.
