Planning for autonomous vehicles : ridesharing and traffic control
This report address two problems that could drive the adoption of autonomous vehicles (AV) – shared autonomous vehicle routing (SAV) problem and the autonomous intersection management system (AIM) location problem. The SAV routing problem is finding the optimal SAV to passenger matching as well as …

SOCIAL NETWORK INFLUENCE ON RIDESHARING, DISASTER COMMUNICATIONS, AND COMMUNITY INTERACTIONS
The complex topology of real networks allows network agents to change their functional behavior. Conceptual and methodological developments in network analysis have furthered our understanding of the effects of interpersonal environment on normative social influence and social engagement. Social …

Migrant Ridesharing Drivers in San Francisco: A Case of Blocked Mobility?
… a newer and understudied form of transportation: ridesharing. This study argues that in the case of the ridesharing industry, drivers did indeed turn to the occupation because of factors such as insufficient English language level and foreign academic degrees, but also age and personal family …

Dynamic Ridesharing under Travel Time Uncertainty: Passenger Preference and Optimal Assignment Methods
… increase in vehicle-kilometers traveled. Dynamic ridesharing (DRS; or pooled ridehailing) provides a means to mitigate these negative externalities by offering reduced fares for passengers in exchange for increased operational flexibility in pooling multiple trips into the same vehicle …

Real-time ridesharing : exploring the opportunities and challenges of designing a technology-based rideshare trial for the MIT community
The potential benefits from increased ridesharing are substantial, and impact a wide range of stakeholders. In a properly applied rideshare scheme, drivers and passengers achieve cost savings, they potentially achieve travel time savings, and they benefit from increased travel options. Employers …

The impact of peer-to-peer ridesharing on travel mode: Empirical study of Uber effects on travel mode in Seattle
Peer-to-peer ridesharing, as a new travel mode, could be a potential solution to two major transportation issues: congestion and air pollution by reducing inefficient driving and promoting public transit ridership. Uber, as one of the leader transport network company, launched in San Francisco in …

Understanding and Designing for Perceptions of Trust in Rideshare Programs
… the number of vehicles on the road based on ridesharing. Nevertheless, ridesharing is not a popular form of public transportation. A ridesharing application involves planning and collaboration in setting up rides. Some of the concerns of users of these applications are social discomfort that …

Discrimination, regulation, and design in ridehailing
… attitudes in the context of dynamic ridesharing. To that end, this thesis uses data from a survey of 1,110 TNC users to argue that discriminatory attitudes toward fellow passengers of differing class and race are positively correlated with demographic and environmental …

Resource allocation and pricing under competition in shared mobility markets
… in their daily operations. For example, in a ridesharing market, significant imbalance between spatiotemporal distributions of vehicle supply and travel demand mandates companies to allocate their resources (e.g., vehicles and drivers) and design pricing strategies optimally to incentivize …

Rider multihoming in the United States rideshare market
This thesis examines rider multihoming in the US ridesharing market. Ridesharing services experience substantial multihoming on both sides of the platform, and appear to suffer from a combination of a lack of differentiation as well as low multihoming costs. Through an informational interview, a …

Matching Algorithm Design in E-Commerce: Harnessing the Power of Machine Learning via Stochastic Optimization
… advertising (matching keywords and advertisers), ridesharing platforms (pairing riders and drivers), crowdsourcing markets (assigning tasks to workers), online dating (pairing romantically attracted partners), etc. A fundamental challenge is the presence of \emph{uncertainty}, which manifests in …

Demand estimation and fleet management for autonomous mobility on demand systems
… QoS in ride hailing, ride requesting, and ridesharing MOD operating frameworks. The planners are evaluated using data-driven simulation of the MIT MOD system. For ride hailing, to address the challenge of missed customers, a chance-constrained planner is introduced for positioning vehicles …

Evaluation of Tidewater district's operations improvements program
… of the common method of relieving congestion, ridesharing, which is being encouraged. The failure of the proper maintenance of the HOV lanes on the Route 44 leading to the subsequent rescinding of the same has been looked into. The use of DYNAMO programming was made in order to simulate the …

Increasing Saudi females' accessibility to employment via car-pooling in Riyadh : measure the realistic commute cost by network computing methods and investigate the share-ability based on actual taxi trip data
… the notion of accessibility; (3) demonstrate ridesharing's capacity of providing greater access for Saudi women based on spatial analysis of the current commute demands and behaviors; (4) and also look at the feasibility of developing ridesharing programs based on network analysis of current …

Smart City Energy Efficient Multi-Modal Transportation Modeling and Route Planning
… namely, cycling, rail, public transit, and ridesharing. We develop different models to predict bike travel times for use in bike share systems (BSSs) using random forest (RF), least square boosting (LSBoost), and artificial neural network (ANN) techniques. We also use cycling Global …

The impact of ride-hailing services on travel behaviour
… ownership. It also questions the impact of ridesharing services on public transport use and the role neighborhood context plays on the link between ride-hailing and car-ownership. This is studied through a Path Analysis implemented through Structural Equation Modelling (SEM). It describes …

ANALYSIS OF SLACK TIME FOR A REAL-TIME RIDESHARE SYSTEM
Ridesharing and carpooling are effective traffic demand management strategies with many benefits comparable to other highway management methods. As a safety factor can increase the reliability of transit systems, a slack time can be added to the passenger pickup schedule to increase the system …

Smart mobility : behavioral data collection and simulation
On-demand ridesharing services, such as Uber and Lyft, and autonomous vehicles are significantly changing the landscape of transportation and mobility. In light of these disruptions, we aim to determine consumer preferences with regards to transportation and use this data to simulate and analyze …

Electrification of transportation sharing economy business models: the ride- and carsharing cases
… transportation is on the rise. In April 2016, ridesharing company Teo Taxi launched a plug-in electric vehicle (PEV) fleet followed four months later by Uber. In 2020 Volkswagen will start a fully-electric carsharing platform, whereas other companies such as BMW already provide such a service. …
