TL;DR: A route choice model with GPS data collected from smartphone users in San Francisco revealed that bicycle lanes were preferred to other facility types, especially by infrequent cyclists, and steep slopes were disfavored.
Abstract: Recognizing the environmental and health benefits of cycling, cities around the world are promoting use of the bicycle for everyday transportation, but with limited information about the preferences of cyclists and the effectiveness of investments in bicycle infrastructure. To better understand the decision-making of cyclists, we estimated a route choice model with GPS data collected from smartphone users in San Francisco. Traces were automatically filtered for activities and mode transfers, and matched to a network model. Alternatives were extracted using repeated shortest path searches in which both link attributes and generalized cost coefficients were randomized. The prior distribution for the coefficients was calibrated automatically using only the network. A Path Size Multinomial Logit model revealed that bicycle lanes were preferred to other facility types, especially by infrequent cyclists. Steep slopes were disfavored, especially by women and during commutes. Other negative attributes inc...

TL;DR: In this paper, the authors present a series of reasons for the paradoxical result that travel and congestion continue to increase with the spread of ever-improving technologies, as well as four reasons why substitution can be expected.
Abstract: Saving travel has always been a motivation for the creation and use of information and communication technologies. So with the ongoing spread of ever-improving technologies, why do travel and congestion continue to increase? Twelve reasons for this paradoxical result are presented, as well as four reasons why some substitution can be expected.

TL;DR: A new household activity survey is presented which uses automated data reduction methods to determine activity and travel locations based on a series of heuristics developed from land-use data and travel characteristics.
Abstract: Using GPS technology in the collection of household travel data has been gaining importance as the technology matures. This paper documents recent developments in the field of GPS travel surveying and ways in which GPS has been incorporated into or even replaced traditional household travel survey methods. A new household activity survey is presented which uses automated data reduction methods to determine activity and travel locations based on a series of heuristics developed from land-use data and travel characteristics. The algorithms are used in an internet-based prompted recall survey which utilizes advanced learning algorithms to reduce the burden placed on survey respondents. Initial results of a small pilot study are discussed and potential areas of future work are presented.

TL;DR: The existing lane changing models are reviewed and the strengths and weaknesses of each model type are assessed, and they are classified according to their characteristics.
Abstract: Lane changing maneuvers have a significant impact on macroscopic and microscopic characteristics of traffic flows due to the interference effect they have on surrounding traffic. Understanding the factors which affect drivers' lane changing behavior is important due to the implication of lane changing models in variety of traffic and transportation studies. This paper reviews the existing lane changing models and assesses the strengths and weaknesses of each model type. In addition, the lane changing models are classified according to their characteristics. Then, limitations of the existing lane changing models are identified. Finally, the findings and conclusions of the paper are summarized and more promising research directions are suggested.

TL;DR: In this paper, the authors describe a new framework for dynamically simulating activity planning and scheduling within an activity-based microsimulation model, which is a process model which attempts to replicate time-dependent activity scheduling.
Abstract: This paper describes a new framework for dynamically simulating activity planning and scheduling within an activity-based microsimulation model. The dynamic activity planning framework is a process model which attempts to replicate time-dependent activity scheduling. By modeling the actual underlying activity and travel planning and scheduling processes rather than revealed activity-travel patterns, the model can represent a much wider range of travel demand management policies, especially policies which are expected to impact the planning process of individuals. In contrast with previous activity scheduling models, the proposed model considers activity scheduling steps as discrete events within the overall activity-travel simulation, and furthermore considers each attribute decision as a separate event. The paper develops a framework for modeling each activity and its attributes, and allows for a non-fixed attribute planning order, so that there is no pre-determined planning order assumed in the ...
