GOOD SAMPLE CONSENSUS ESTIMATION OF 2D-HOMOGRAPHIES FOR VEHICLE MOVEMENT DETECTION FROM THERMAL VIDEOS
Infrared surveillance Machine vision Object recognition
2015/5/18
In this contribution we describe a method to assess the activity of vehicles based on airborne image sequences taken by an infrared
camera. Active vehicles often appear as a configuration of a dark a...
The impact of weight matrices on parameter estimation and inference: A case study of binary response using land-use data
Spatial autoregressive probit model Matrix exponential spatial specification Distance decay Bayesian estimation Land use change
2013/11/21
This paper develops two new models and evaluates the impact of using different weight matrices on parameter estimates and inference in three distinct spatial specifications for discrete response. Thes...
An Agent-Based Model of Origin Destination Estimation (ABODE)
Transport Modeling Trip Distribution Job-Worker matching
2013/11/21
This paper proposes and tests an agent-based model of worker and job matching. The model takes residential locations of workers and the locations of employers as exogenous and deals specifically with ...
Bus transit operations are influenced by stochastic variations in a number of factors
(e.g., traffic congestion, ridership, intersection delays, and weather conditions) that
can force buses to devia...
A Methodology for the Estimation of Value-of-Time Using State-of-the-Art Econometric Models
Methodology Value-of-Time State-of-the-Art Econometric Models
2009/10/16
Value-of-time (VOT) measures are valuable in a wide range of public transport
policy and planning applications. However, VOT is a latent variable that cannot be
measured directly. In this research, ...
A New Method for Travel Time Estimation on Long Freeway Sections
freeway traffic image processing pattern recognition
2009/9/29
The knowledge of travel times on road networks is of vital importance for network operators as well as for drivers. Operators can use travel time information to improve control on their networks. Driv...

accident prediction model artificial neural network (ANN) genetic algorithm injury Ankara
2010/11/1
This study proposes an Artificial Neural Network (ANN) model and a Genetic Algorithm (GA) model to estimate the number of accidents (A), fatalities (F) and injuries (I) in Ankara, Turkey, utilizing th...
Theoretical estimation of the environmental impact of biofuel mixtures
biofuel ethanol biodiesel environmental impact
2010/11/1
Vehicles are burning fuels inefficiently. Nowadays, there is a strong correlation between CO2 emission and climate change. The article estimates a theoretical environmental impact of biofuel mixtures ...
Estimation of Vehicle Flows and Emissions for Various Scenarios of Street Network Modifications in Mexico City
Metropolitan network vehicle flow emission road infrastructure
2008/12/26
We estimate flows and emissions (NOx, HC, CO) generated by vehicles circulating on the main streets of the Mexico City Metropolitan Area. The estimation is made for various scenarios, which include a ...
Estimation of the need for harmonization of technical demands for vehicles used in transit countries to decrease threats made by the accidents, presented in the selected examples
safety transport visibility
2010/11/1
The paper shows the need to make harmonization of the technical demands concerning the vehicles used in the traffic. The vehicles moving now on the roads in the transit countries were allowed to be dr...
