Layout of roads and streets

1. Layout of Roads and Streets
Presentation Topic

2. What is Layout
• Deciding on the best physical arrangement of all resources that
consume space within a facility
• The way in which the parts of something are arranged or laid out.
• The way in which text or pictures are set out on a page.
• The process of setting out material on a page or in a work.

3. Layout of Roads
• Schematic Layouts for Roads :
• The submission of schematic layouts should include the basic information necessary for
the proper review and evaluation of the proposed improvement:
• General project information including project limits, design speed, and functional
classification.
• The location of interchanges, mainlines, grade separations, frontage roads, turnarounds,
and ramps.

4. • Existing and proposed profiles and horizontal alignments of main
lanes, ramps, and crossroads at proposed interchanges or grade
separations. Frontage road alignment data need not be shown on
the schematic, however, it should be developed in sufficient detail to
determine right of way needs.
• For freeways, the location and text of the proposed main lane guide
signs should be shown. Lane lines and/or arrows indicating the
number of lanes should be shown.
• For freeway added capacity projects, a capacity analysis.

5. • An explanation of the sequence and methods of stage construction
including initial and ultimate proposed treatment of crossovers and
ramps.
• The tentative right of way limits.
• Bridges and bridge class culverts should be shown.
• The geometrics (pavement cross slope, super elevation, lane and
shoulder widths, slope ratio for fills and cuts) of the typical sections of
proposed highway main lanes, ramps, frontage roads, and cross
roads.

6. • Location of retaining walls and/or noise walls.
• The existing and proposed traffic volumes and, as applicable,
turning movement volumes.
• If applicable, the existing and proposed control of access lines.

7. Layout of streets
• street layout are also important to travel. The relationships between buildings,
streets and open spaces form the urban fabric that helps to give a neighborhood its
physical identity.

8. • “The physical form and qualities of a place, shape - and are shaped
by - the way it is used and the way people and vehicles move
through it. New development should help to create places that
connect with each other sustainably, providing the right conditions to
encourage walking, cycling and the use of public transport. People
should come before traffic. Places that work well are designed to be
used safely and securely by all in the community, frequently for a
wide range of purposes and throughout the day and evening.”

9. • “Matters to consider when assessing design quality include the
extent to which the proposed development:
• Is easily accessible and well-connected to public transport and
community facilities and services, and is well laid out so that all the
space is used efficiently, is safe, accessible and user-friendly.
• Is well integrated with, and complements, the neighboring buildings
and the local area more generally in terms of scale, density, layout
and access.
• Takes a design-led approach to the provision of car-parking space,
that is well-integrated with a high quality public realm and streets
that are pedestrian, cycle and vehicle friendly
