MODEL FOR DETERMINING OPTIMUM BUS-STOP SPACING IN URBAN AREAS
- A. A. Saka
- 1 June 2001
This paper proposes a model that can be used to determine effectively a sub-optimal policy for bus-stop spacing in urban areas. Transit users are usually interested in minimizing their out-of-vehicle…
Alternative method of highway traffic safety analysis for developing countries using delphi technique and Bayesian network.
Estimation of Mobile Emissions Reduction from Using Electronic Tolls
It was determined from the simulation and mobile emissions models that the current deployment level of M-Tag has improved the average travel speed by more than 125% and has decreased the mobile emissions rate by up to 41% at the Fort McHenry Tunnel toll plaza.
EFFECT OF BUS-STOP SPACING ON MOBILE EMISSIONS IN URBAN AREAS
- A. A. Saka
- Environmental Science
The operational effect of bus-stop spacing has been a critical issue. Closely spaced bus stops disrupt the traffic flow on the bus route, particularly during peak hours because buses make frequent…
Evaluation of the Impact of Pavement Roughness on Vehicle Gas Emissions in Baltimore County
Gas emissions originating from the land transportation mode is one of the elements contributing to global warming. Both the amount and the type of gas emitted depend on factors such as vehicle size,…
Traffic recovery time estimation under different flow regimes in traffic simulation
Traffic signal timing at isolated intersections using simulation optimization
Two innovative stochastic traffic signal optimized techniques for isolated intersections are discussed and the suitability of the optimization techniques for undersaturated and oversaturated flow conditions; and steady state and nonstationary queue conditions are discussed.
MITIGATION OF SIGHT-DISTANCE PROBLEM FOR UNPROTECTED LEFT-TURNING TRAFFIC AT INTERSECTIONS
Sight-distance problems at intersections are often discussed in the context of visual obstructions caused by permanent objects such as trees, parked vehicles, and buildings. Very little investigation…
Modeling Highway Traffic Safety in Nigeria Using Delphi Technique and Bayesian Network
Highway traffic safety is an issue confronting developing countries and those of industrialized nations. Many people are injured and/or killed all over the world daily on highway traffic related…
An Estimation of Mobile Emissions Reduction from Using Electronic Toll Collection in the Baltimore Metropolitan Area: A Case Study of the Fort McHenry Tunnel Toll Plaza
It was determined from the simulation and mobile emissions models that the current deployment level of M-Tag has improved the average travel speed by more than 125% and has decreased the mobile emissions rate by up to 41% at the Fort McHenry toll plaza.
