Grade separation is a form of intersection in which one or more conflicting movements of intersecting highways are segregated in space. An interchange is a grade separation with connecting roadways which allow route transfer between the intersecting highways. An interchange is therefore, the highest form of intersection design.

• At-grade intersections with indirect left turns using a U -turn movement in a wide median and/or loon • The MUT eliminates direct left turns on both intersecting streets, reducing the number of signal phases and conflict points at the main intersection MUT – Median U-Turn

It is suggested that AASHTO geometric design policy emphasize the appropriateness of at-grade intersections as ramp terminals. Grades in excess of 3 percent should, therefore, be avoided on intersections while those in excess of 6 percent should not be allowed. Encourage low vehicle speeds on the approaches to right-angle intersections- Minor road vehicles intending to cut across major road traffic should approach the intersection slowly so that they can easily stop and give way to through traffic. APSEd Website: https://learn.apsed.in/Enrol today in our site https://learn.apsed.in/ and get access to our study package comprising of video lectures, study Chapter Twenty-eight discusses the geometric design of at-grade intersections including intersection alignment and profile, right-turn designs, turning lanes, turning roadways, intersection sight distance, channelization, median openings and approaches. The intersection is an important part of the highway system.

7.1 TYPES OF AT-GRADE INTERSECTIONS The basic types of at-grade intersections are T or three-leg intersections which consist of three approaches; four-leg or cross intersections, which consist of four approaches; and multi-leg intersections, which consist of five or more approaches. Intersection Design 7.1.1 T Intersections Curves at grade intersection are provided for smooth and safe transition of the two grades as part of highway alignment. Various types of horizontal curves are essential for the gradual change in direction. These curves are needed when the direct point of intersection is not feasible.

GRADE INTERSECTION • An intersection is an at-grade junction where two or more roads or streets meet or cross at same level. • They are classified as 1. Un channelized intersection 2. Channelized intersection 3.

speed. Effective intersection control and traffic interface design are the key elements in successful at-grade LRT design. Yet experience in this field is still limited, and beset with miscon-ceptions that can distort, or even fore-close, a project in the planning stages, before potential problem resolution can occur.

The following are three basic types of at grade intersections: a) Unchannelised and Unflared Intersections They are normally adequate where minor roads meet. At Grade Intersections The intersection are generally found at locations where a major road and minor streets meet, two major roads intersect, etc. The intersections require a signal system, which is to be designed based on number of vehicles arriving at the intersection.

The basic types of at -grade intersections are the T -intersection (with multiple variations of angular approach), the four-leg intersection, the multi-leg intersections and roundabouts (see Chapter 19 of this Guide for roundabout design guidelines). In each particular case, the type is determined

At-Grade Intersection can be divided into four major categories: 1) Uncontrolled Intersections-These types of intersections occur where the intersecting roads are of relatively equal importance and when traffic volumes are so light that no form of control or road sign appears necessary. 2) Priority

The basic forms of at-grade intersections are shown in Fig. 5.2.
