Geometric Design for Roadway Intersection Lines

: An intersection is an important part of a highway system because, to a great extent, the efficiency, safety, speed, cost of operation, and capacity depends on its design. Each intersection involves through or cross-traffic movements on one or more of the highways concerned and may involve turning movements between these highways. These movements may be handled by various means, such as signals, signing, and channelization, depending on the type of intersection. Traffic loads are one of the key data elements required for the design and analysis of pavement structures. The MEPDG requires full axle-load spectrum mainly based on continuous site-specific Weigh-In-Motion (WIM) data sets for each axle type and axle- load group. Due to the fact that collecting high quality WIM data is expensive, challenging and analyzing them requires extensive efforts and expertise, many state DOTs have to rely on traffic data from various acquisition technologies and length of time coverage for the implementation of MEPDG This paper studies the impacts and variability of various traffic data collection efforts on MEPDG predicted performance. Geometric design process for modern roadway intersections. The contents of this document are intended to serve as guidance and not as an absolute standard or rule. The impacts of traffic load level, WIM data coverage, vehicle distribution, axle loading, and using regional and national defaults on predicted pavement performance are evaluated. This study has recommended the minimum required traffic data collection efforts for highway agencies to prepare traffic data for the implementation of MEPDG. The traffic characteristic of a corridor is required for design of pavement, fixing a number of traffic lanes, geometric design, design of intersections and economic appraisal. Traffic is the first thing to check before upgrading any facility. In this study, In order to understand the characteristics and the volume of traffic using the project road.
