ASCE - A Better Approach to Access Management (AWI030411) Course
This seminar provides hands-on training for engineers and planners on how to effectively manage accesses serving new and existing office, commercial and industrial uses. The presentation will focus on how to optimize the spacing and design characteristics of driveways to minimize the impacts on major street operations as well as the potential for crashes. The needs of all road users (motorists, pedestrians, and bicyclists) will also be addressed. Necessary tools and good practices for providing well planned access to a variety of development projects, from the perspectives of both the agency and the developer proposing the project, are covered. The best sources of additional information on each topic will be identified. Numerous examples will be provided illustrating both good and bad examples of access management and the impacts to the overall operation of these high volume corridors.
You will learn about:
- Network hierarchy planning
- Intersection planning
- Access location and design
- Medians and median openings
- Traffic signal/freeway spacing
- Turn lane warrants and lengths and designing for human factors
- Best practices for managing access and how to limit turning movements at unsignalized accesses
- How to design signalized and unsignalized driveways to provide unimpeded flow for motorized traffic while balancing the needs of pedestrians and other nonmotorized users
- Gain a better understanding of access management and design
- Learn about the impacts of various designs on traffic flow
- Identify best sources of additional information/references
- Learn from examples illustrating good and bad designs
Intended Audience
• Transportation professionals (engineers and planners)
• Consulting firms, cities, counties, and state agencies involved in reviewing and designing access to development projects
This course is designed for individuals with and without background or training in designing commercial and office type development projects.
- Access management and control
- Benefits of access management
- Designing from outside in (until the access operation area is cleared)
- Restricting turning movements (medians, reducing severity types)
- Criteria for requiring auxiliary lanes
- Left and right-turn lane design parameters
- Improving driveway operations (driveway design elements)
- Corner radius and driveway widths
- Designs that meet pedestrian and bicyclists needs
- Throat length and alignment
- Driveway profile and grade
- Sight distance & preserving the sight distance
