Travel and the Built Environment: A Synthesis
Tập 1780 Số 1 - Trang 87-114 - 2001
The potential to moderate travel demand through changes in the built environment
is the subject of more than 50 recent empirical studies. The majority of recent
studies are summarized. Elasticities of travel demand with respect to density,
diversity, design, and regional accessibility are then derived from selected
studies. These elasticity values may be useful in travel forecasting and sketch
pla...
Surrogate Safety Measures from Traffic Simulation Models
Tập 1840 Số 1 - Trang 104-115 - 2003
Safety is emerging as an area of increased attention and awareness within
transportation engineering. Historically, the safety of new and innovative
traffic treatments has been difficult to assess, primarily because of a lack of
good predictive models of crash potential and a lack of consensus on what
constitutes a safe or unsafe facility. An FHWA-sponsored research project
investigated the potent...
Measuring Sprawl and Its Transportation Impacts
Tập 1831 Số 1 - Trang 175-183 - 2003
Across the United States, urban sprawl, its impacts, and appropriate containment
policies have become the most hotly debated issues in urban planning. Today’s
debates have no anchoring definition of sprawl, which has contributed to their
unfocused, dogmatic quality. Efforts to measure sprawl and test for
relationships between sprawl and transportation outcomes are described. This is
the first use ...
Estimating Acceleration and Lane-Changing Dynamics from Next Generation Simulation Trajectory Data
Tập 2088 Số 1 - Trang 90-101 - 2008
The Next Generation Simulation (NGSIM) trajectory data sets provide longitudinal
and lateral positional information for all vehicles in certain spatiotemporal
regions. Velocity and acceleration information cannot be extracted directly
because the noise in the NGSIM positional information is greatly increased by
the necessary numerical differentiations. A smoothing algorithm is proposed for
positio...
Optimal Location of Charging Stations for Electric Vehicles in a Neighborhood in Lisbon, Portugal
Tập 2252 Số 1 - Trang 91-98 - 2011
Growing concerns about environmental issues have led to the consideration of
alternatives to current mobility. Electric mobility is one such alternative that
is receiving a great deal of attention in Europe. In particular, a new legal
framework for the introduction of an electric mobility system in Portugal has
recently been set up by the government. A key issue in this system is recharging
the ba...
Predicting Freeway Crashes from Loop Detector Data by Matched Case-Control Logistic Regression
Tập 1897 Số 1 - Trang 88-95 - 2004
Growing concern over traffic safety has led to research into prediction of
freeway crashes in an advanced traffic management and information systems
environment. A crash likelihood prediction model was developed by using
real-time traffic flow variables (measured through a series of underground
sensors) potentially associated with crash occurrence. The issues related to
real-time application, incl...
Modeling Integrated Lane-Changing Behavior
Tập 1857 Số 1 - Trang 30-38 - 2003
The lane-changing model is an important component within microscopic traffic
simulation tools. Following the emergence of these tools in recent years,
interest in the development of more reliable lane-changing models has increased.
Lane-changing behavior is also important in several other applications such as
capacity analysis and safety studies. Lane-changing behavior is usually modeled
in two st...
Real-Time Crash Prediction Model for Application to Crash Prevention in Freeway Traffic
Tập 1840 Số 1 - Trang 67-77 - 2003
The likelihood of a crash or crash potential is significantly affected by the
short-term turbulence of traffic flow. For this reason, crash potential must be
estimated on a real-time basis by monitoring the current traffic condition. In
this regard, a probabilistic real-time crash prediction model relating crash
potential to various traffic flow characteristics that lead to crash occurrence,
or “c...
Application of Probe-Vehicle Data for Real-Time Traffic-State Estimation and Short-Term Travel-Time Prediction on a Freeway
Tập 1855 Số 1 - Trang 49-59 - 2003
Traffic information from probe vehicles has great potential for improving the
estimation accuracy of traffic situations, especially where no traffic detector
is installed. A method for dealing with probe data along with conventional
detector data to estimate traffic states is proposed. The probe data were
integrated into the observation equation of the Kalman filter, in which state
equations are r...
Day-to-Day Travel-Time Trends and Travel-Time Prediction from Loop-Detector Data
Tập 1717 Số 1 - Trang 120-129 - 2000
An approach is presented for estimating future travel times on a freeway using
flow and occupancy data from single-loop detectors and historical travel-time
information. Linear regression, with the stepwise-variable-selection method and
more advanced tree-based methods, is used. The analysis considers forecasts
ranging from a few minutes into the future up to an hour ahead. Leave-a-day-out
cross-v...
