Semi-on-Demand Hybrid Transit Route Design with Shared Autonomous Mobility Services
This study examines the route design of a semi-on-demand hybrid route directional service in the public transit network, offering on-demand flexible route service in low-density areas and fixed route service in higher-density areas with Shared Autonomous Mobility Service (SAMS).
Temporal Enhanced Floating Car Observers
Floating Car Observers (FCOs) are an innovative method to collect traffic data by deploying sensor-equipped vehicles to detect and locate other vehicles.
Unlocking Past Information: Temporal Embeddings in Cooperative Bird's Eye View Prediction
TempCoBEV is an independent temporal module that seamlessly integrates into state-of-the-art camera-based cooperative perception models.
Effects of Dynamic and Stochastic Travel Times on the Operation of Mobility-on-Demand Services
As travel times in real street networks are dynamic and stochastic, assigned routes considered feasible by the control algorithm in one time step might become infeasible in the next.
Predictive Vehicle Repositioning for On-Demand Ride-Pooling Services
This imbalance would lead to low fleet utilization and high customer waiting times.
The Mobilität.Leben Study: a Year-Long Mobility-Tracking Panel
The announcement of a successor ticket to the 9-Euro-Ticket, the so-called Deutschlandticket, led to the immediate decision to continue the study.
Autonomous Vehicles as a Sensor: Simulating Data Collection Process
Nevertheless, the relentless progression in autonomous driving technology has catalyzed an increasing interest in capitalizing on the extensive potential of on-board sensor data, giving rise to a novel concept known as "Autonomous Vehicles as a Sensor" (AVaaS).
Germany's nationwide travel experiment in 2022: public transport for 9 Euro per month -- First findings of an empirical study
We observe this natural experiment with a three-wave survey and a smartphone-based travel diary with passive tracking on an initial sample of 2, 261 participants with a focus on the Munich metropolitan region.
A nation-wide experiment, part II: the introduction of a 49-Euro-per-month travel pass in Germany -- An empirical study on this fare innovation
In a response to the 2022 cost-of-living crisis in Europe, the German government implemented a three-month fuel excise tax cut and a public transport travel pass for 9 Euro per month valid on all local and regional services.
A nation-wide experiment: fuel tax cuts and almost free public transport for three months in Germany -- Report 5 Insights into four months of mobility tracking
We observe this natural experiment with a three-wave survey and an app-based travel diary on a sample of hundreds of participants as well as an analysis of traffic counts.
A nation-wide experiment: fuel tax cuts and almost free public transport for three months in Germany -- Report 4 Third wave results
Based on our results we conclude that when offering a 49EUR-Ticket as a successor to the 9~EUR-Ticket and a local travel pass for 30EUR/month more than 60% of all 9~EUR-Ticket owners would buy one of the two new travel passes.
Simulating Ride-Pooling Services with Pre-Booking and On-Demand Customers
That the graph-based batch optimization is superior to a basic insertion method in terms of solution quality and run-time.
A nation-wide experiment: fuel tax cuts and almost free public transport for three months in Germany -- Report 3 Second wave results
In spring 2022, the German federal government agreed on a set of measures that aimed at reducing households' financial burden resulting from a recent price increase, especially in energy and mobility.
A nation-wide experiment: fuel tax cuts and almost free public transport for three months in Germany -- Report 2 First wave results
We observe this natural experiment with a three-wave survey and an app-based travel diary on a sample of hundreds of participants as well as an analysis of traffic counts.
A nation-wide experiment: fuel tax cuts and almost free public transport for three months in Germany -- Report 1 Study design, recruiting and participation
In spring 2022, the German federal government agreed on a set of measures that aim at reducing households' financial burden resulting from a recent price increase, especially in energy and mobility.
MobilityCoins -- A new currency for the multimodal urban transportation system
The MobilityCoin is a new, all-encompassing currency for the management of the multimodal urban transportation system.
Multi-Sensor Data Fusion for Accurate Traffic Speed and Travel Time Reconstruction
A novel fusion approach is developed which extends existing speed reconstruction methods to integrate low-resolution travel time data.
Estimating Traffic Speeds using Probe Data: A Deep Neural Network Approach
The results show that the DNN is able to apply learned patterns, and reconstructs moving as well as stationary congested traffic with high accuracy; even given highly sparse input data.
On the Dynamism of User Rejections in Mobility-on-Demand Systems
Under certain assumptions, which are reasonable for an attractive MoD business model, it can be shown that an operator using dynamic state optimization can communicate a rejection to users after the first iteration, thereby eliminating unnecessary waiting time before these users would leave the system.
Feature Engineering for Data-driven Traffic State Forecast in Urban Road Networks
Most traffic state forecast algorithms when applied to urban road networks consider only the links in close proximity to the target location.
Optimal internal boundary control of lane-free automated vehicle traffic
A recently proposed paradigm for vehicular traffic in the era of CAV (connected and automated vehicles), called TrafficFluid, involves lane-free vehicle movement.
