Modified Delay Equations for Permitted Left Turns
(American Society of Civil Engineers, 1998)For permitted left turns at signalized intersections from exclusive or shared lane groups with multiple opposing lanes, this paper proposes modifications to the delay equation used in the 1994 -
Speed and Delay on Signalized Arterials
(American Society of Civil Engineers, 1998)This paper presents a model to predict the influence of traffic flow on the running speed of signalized arterials in Montgomery County, Maryland, while controlling for link length, the number of lanes, and route type. The ... -
Ordered Probability Modeling of Seat Belt Usage
(American Society of Civil Engineers, 1998)This paper develops a new method to examine the factors that influence driver's seat belt usage. A binary logit model of the driver's beliefs in the effectiveness of seat belts is first developed. The seat belt beliefs ... -
Utilization of Double Left-Turn Lanes with Downstream Lane Reductions
(American Society of Civil Engineers, 1998)The capacity of left-turn movements at signalized intersections is sometimes increased by using two exclusive double left-turn lanes at the intersection followed by a reduction to a single lane after the turn is made. A ... -
Discrete-Time Dynamic User-Optimal Departure Time/Route Choice Model
(American Society of Civil Engineers, 1998)This paper concerns a discrete-time, link-based, dynamic user-optimal departure time/route choice model using the variational inequality approach. The model complies with a dynamic user-optimal equilibrium condition in ... -
Pedestrian Route Choices between Escalator and Stairway in MTR Stations
(American Society of Civil Engineers, 1998)Passenger demands on underground stations are always excessive and can cause severe congestion. The study of pedestrian behavior is particularly important in planning and design of the underground stations during peak ... -
Approaching <b><i>OD</i></b> Trip Volumes Based on Inverse T-V Equation
(American Society of Civil Engineers, 1998)An inverse trip distribution-volume of link flow (T-V) equation is derived by the introduction of a new concept, the pass through coefficient. Based on this, a new approach to calculate -
Lane Volume and Saturation Flow Rate for Multilane Intersection Approach
(American Society of Civil Engineers, 1998)One factor that can reduce a lane's saturation flow to less than ideal conditions is when turning vehicles share the lane with through vehicles. The slow discharge rate of the turning vehicles reduces the lane's effective ... -
Network-Based Simulation of Aircraft at Gates in Airport Terminals
(American Society of Civil Engineers, 1998)Simulation is becoming an essential tool for planning, design, and management of airport facilities. A simulation of aircraft at gates at an airport can be applied for various periodically performed applications, relating ... -
Effect of Dynamic Sight-Distance Problem on Unprotected Left-Turn Movement Capacity
(American Society of Civil Engineers, 1998)Classical sight-distance problems involve the horizontal and vertical alignment of the road and stationary objects around the roadway that interfere with the motorist's view. Dynamic sight-distance problems concern the ... -

Shortcut Estimation of Safety Distances of Pipelines from Explosives
(American Society of Civil Engineers, 1998)Purposely or accidentally detonating explosives near pressurized gas pipelines may have severe consequences on them, ranging from permanent deformation to gas loss or even violent rupture. Owing to lack of analytical ... -
Speed-Flow Modeling of Arterial Roads in Singapore
(American Society of Civil Engineers, 1998)Traffic volume and travel time data collected at a number of arterial roads in Singapore were used to analyze the speed-flow relationships for radial and ring arterial roads. A new travel time–density model was formulated ... -
Estimating Hazen-Williams Coefficient for Polyethylene Pipes
(American Society of Civil Engineers, 1998)Polyethylene is the predominant pipe material for trickle irrigation laterals and submains because of its flexibility and resistibility to the sun. Laboratory experiments have been conducted to determine the proper values ... -
Delay at Signal-Controlled Intersection with Bus Stop Upstream
(American Society of Civil Engineers, 1998)Because of the tight constraints on many streets in urban areas, it is not uncommon to situate a bus stop upstream of a signal-controlled intersection without the provision of a proper bus bay or setback. For a single-lane ... -
Analyzing Freeway Traffic under Congestion: Traffic Dynamics Approach
(American Society of Civil Engineers, 1998)This paper presents an analysis of freeway traffic flows under congestion based on the principle of traffic dynamics, using the example of recurring congestion. Queuing and discharging mechanisms are analyzed using the ... -
Spatial Variations in Travel Behavior within Greater Toronto Area
(American Society of Civil Engineers, 1998)Rapid suburbanization of housing and employment has produced severe traffic congestion in North American cities. One response to this problem in the greater Toronto area (GTA) has been to identify urban forms that are more ... -
Michigan's Commercial Driver's License (CDL) Experience
(American Society of Civil Engineers, 1998)The Commercial Motor Vehicle Safety Act (CMVSA) of 1986 established uniform federal standards for testing and licensing to ensure the “fitness” of persons who operate commercial motor vehicles. The purpose of the research ... -
Three-Arc Vertical Curve for Constrained Highway Alignments
(American Society of Civil Engineers, 1998)Existing symmetrical and unsymmetrical (two-arc) vertical curves may not be feasible when the highway alignment is subject to physical constraints (e.g., vertical clearance) and the beginning and end of the vertical curve ... -
Model for Sight-Distance Analysis of Uncontrolled Intersections
(American Society of Civil Engineers, 1998)The American Association of State Highway and Transportation Officials (AASHTO) model of calculating sight distance at intersections without control (Case I) has been modified to explicitly incorporate the design speeds ...
