Study Notes
Primary Goal of Traffic Engineers
- Aim for safe, efficient movement of people and goods on streets and highways.
- Key objectives include improving safety, relieving traffic congestion, ensuring speed and comfort, providing convenience, enhancing economy, and protecting the environment.
Elements of Traffic Engineering
- Traffic Studies: Measure and quantify highway traffic, including volume, speed, travel time, and delays.
- Performance Evaluation: Assesses operating characteristics of traffic facilities via levels of service.
- Facility Design: Focuses on functional and geometric design of highways and traffic facilities.
- Traffic Control: Establishes traffic regulations communicated through signs, markings, and signals.
- Traffic Operations: Influences overall traffic facility operation through measures like one-way street systems and network control systems.
Vehicle Types
- Categories include motor-tricycles, motorcycles, various passenger cars (sedan, SUV), small and large buses, goods utility vehicles, and various rigid and trailer trucks.
Manual Classified Volume Count
- Counts conducted for specific durations (24-hour, 16-hour, 12-hour) to analyze traffic volume at midblock and intersections during peak times.
Presentation of Data
- Utilizes trend charts, intersection flow diagrams, and traffic flow maps to visualize traffic data.
Application of Traffic Volume Data
- Supports design of road rehabilitation projects, traffic system studies, traffic volume forecasting, accident studies, and cost-benefit analysis for highway projects.
Spot Speed Studies
- Measure distribution of vehicle speeds at specific locations by recording speeds of sample vehicles.
- Valid only under current traffic and environmental conditions.
Study of Traffic Engineering
- Involves long-term planning for regions, integrating land use, transportation needs, and road networks.
- Geometric design includes roadway details and configurations for optimal performance.
- Traffic operations encompass regulations and control measures, including speed limits and installation of traffic control devices.
- Road safety focused on systematic management of local traffic conditions.
