In this paper, we model and simulate special use cases of on-demand shared mobility services for the City of Ann Arbor, MI. We define shared mobility as any motor-vehicle-served transportation option between private vehicles and public transit, such as taxis, demand-responsive transit, and dynamic shuttles. Here, we present and evaluate a suite of four different service types that could potentially complement existing transportation services in Ann Arbor. A novel aspect of this study is that it tests scenarios that were developed in consultation with city planners looking for insights into real-world problems. This study used fleet simulation software to test four service configuration scenarios for a hypothetical on-demand shared mobility service: citywide shuttle, a corridor-based downtown shuttle, a park and ride shuttle, and a transit-complementary service. Three levels of demand were tested for each scenario: 3%, 9%, and 15% of all private vehicle trips in the city. Findings indicated that citywide on-demand shared mobility services struggled to achieve higher vehicle occupancies than private vehicles at approximately 1.4. Service configurations with aggregated trip density resulted in slightly improved occupancies, as found in downtown- and park and ride shuttle scenarios. More impactful was aggregating demand by moving from “many-to-many” routing as with citywide floating services to “many-to-one” routing as with downtown- or park and ride shuttle services, which increased vehicle occupancy from 1.4 to almost 2. Lastly, we also discuss the potential benefits of reduced congestion and parking needs.

One of the main problems to be solved by the transport operators is the substantiation of the vehicle models servicing the transport lines. A gametheoretical approach is proposed in this paper to justify the bus model choice based on the passengers’ preferences and the structure of the passenger flows. To estimate the customers’ preferences, the membership functions for fuzzy sets of the optimal vehicle models were defined. The simulation experiment aiming to estimate the city fleet structure in terms of the vehicles’ capacity was conducted for the Talas city (Kazakhstan) based on the proposed approach with use of the corresponding software implementation of the developed mathematical models. As a result of the experimental studies, the impact of the passengers’ flow structure and the number of carriers on the rational structure of the city bus fleet was studied in the paper.

We study customer preference for the bike-share system in the city of London. We estimate a structural demand model on the station network to learn the preference parameters and use the estimated model to provide insights on the design and expansion of the bike-share system. We highlight the importance of network effects in understanding customer demand and evaluating expansion strategies of transportation networks. In the particular example of the London bike-share system, we find that allocating resources to some areas of the station network can be 10 times more beneficial than others in terms of system usage and that the currently implemented station density rule is far from optimal. We develop a new method to deal with the endogeneity problem of the choice set in estimating demand for network products. Our method can be applied to other settings in which the available set of products or services depends on demand.

Pertumbuhan industri di Batam mengakibatkan jumlah penduduk di Batam mengalami peningkatan. Peningkatan jumlah penduduk berdampak kepada permintaan fasilitas kota yang memadai untuk memenuhi kebutuhan penduduk kota Batam. Salah satu fasilitas tersebut adalah tersedianya pasar, sebagai tempat pemenuhan kebutuhan pokok seperti sandang dan pangan. Fenomena yang muncul di Batam adalah berkembangnya pasar kaget sebagai salah satu jenis pasar tradisional yang  ada hampir diseluruh kecamatan, perumahan yang ada di kota Batam. Tujuan penelitian ini adalah untuk mengetahui sejarah dan berkembangnya pasar kaget di Batam tahun 1980 hingga tahun 2015. Penelitian ini adalah penelitian kualitatif historis dengan pendekatan sosial ekonomi. Metode penelitian yang digunakan adalah metode sejarah yang mencakup heuristik (pengumpulan sumber), kritik sumber, interpretasi, dan historiografi. Berdasarkan hasil penelitian diperoleh pasar kaget telah ada di Batam sejak tahun 1990, berawal dari aktivitas jual beli di pelabuhan yang kemudian berkembang menjadi pasar kaget. Pasar kaget merupakan pasar yang tidak mendapatkan izin beroperasi (illegal) dari Dinas Pasar kota Batam. Berkembangnya pasar kaget akibat harga bahan pokok yang dijual lebih murah dibandingkan pasar tradisional lainnya. Kata Kunci: Kota Batam, Pasar Kaget, Pasar TradisionalIndustrial growth in Batam resulted in a population increase. The increase of population impacts on demand for extra facilities to meet Batam citizen needs. One such facility is the availability of the market, as the fulfillment of basic needs such as food and clothing. The phenomenon that appears in Batam is a growing market in shock as one of the traditional market in nearly all districts, housing in the city of Batam. The purpose of this study is to know the history and development of shock market in Batam from 1980 to 2015. This study is a qualitative study of historical approach to social and economic. The method used is the historical method that includes heuristics (collection of sources), source criticism, interpretation, and historiography. Based on the results obtained surprised the market has been in Batam since 1990, started from the trading activity in the harbor which later evolved into shock market. Shocked the market is a market that did not get permission to operate (illegal) from the Office of the market town of Batam. The growing market shock due to the price of basic commodities are sold cheaper than other traditional markets.Keywords: Batam city, shocked the market, traditional market

Abstract Crowd-shipping is a promising shared mobility service that involves the delivery of goods using non-professional shippers. This service is mainly intended to reduce congestion and pollution in city centers but, as some authors observe, in most crowd-shipping initiatives the crowd rely on private motorized vehicles and hence the environmental benefits could be small, if not negative. Conversely, a crowd-shipping service relying on public transport should maximize the environmental benefits. Motivated by this observation, in this study we assess the potentials of crowd-shipping based on metro commuters in the city of Brescia, Italy. Our contribution is twofold. First, we analyze the results of a survey conducted among metro users to assess their willingness to act as crowd-shippers. The main result is that most young commuters and retirees are willing to be crowd-shippers even for a null reward. Second, we assess the potential economic impact of using metro-based crowd-shipping coupled with a traditional home delivery service. To this end, we formulate a variant of the VRP model where the customers closest to the metro stations may be served either by a conventional vehicle or by a crowd-shipper. The model is implemented using Python with Gurobi solver. A computational study based on the Brescia case is performed to get insights on the economic advantages that a metro-based crowd delivery option may have for a retailing company.

The objective of this paper is to highlight important differences between taxis and transportation network companies (TNCs) in a large urban area. We analyze the publicly available dataset from Chicago which includes taxi and transportation network company (TNC) utilization and the level of service measures from five months in 2013–2014 and the same five months in 2018–2019. We compare and contrast the data from these two points in time to document utilization of taxis and TNCs and to measure differences in travel times, travel distances, fares, destinations served, and the spatial and temporal distribution of these trips. Travel to and from airports has been evaluated separately owing to the exceptionally high number of trips they generate. Striking differences between pooled and unpooled TNC trip volumes and other travel metrics have been assessed to highlight their operational diversity despite being considered as the same mode. The exploratory analysis has been carried out across the shared-ride, time, and mode dimensions. The study revealed both similarities and differences in taxi trip characteristics between the two evaluation periods and also outlined how the ridehailing market has grown over the years despite the near stagnation in population and employment in the city. We believe that assessing how taxis have fared through this time and highlighting the intrinsic differences between how the old and new mode of on-demand ride services coexist is important. This study aims to help understand how new-age mobility services are impacting transportation in one of the largest cities in the U.S.
