Paper Details

Goods transportation facility is important for the development of any region or country road transportation isplaying key role for door to door delivery of the passengers as well as of the goods. Well planned and efficient roadnetwork is necessary for safe, economic and timely transportation road links and junction shall be well designed forsmooth and safe traffic operation. Particularly T-junction on rural highway shall be provide with proper channelization,islands making and signs to avoid accidents generally during the light over turning incidents happen frequently if properreflective sign boards and making are not provide on T-junction. when number of incidents increased, grade separatedjunction (fly over bridge) shall be recommended as a safe infrastructure.Considering these, a T-junction located on Modasa-Shamalaji highway (SH-59) and modasa by-pass road isselected for improvement in this study. A heavy traffic of multi axel loaded trucks is continuously crossing this junction(Average 855 number of trucks per day). 350 number of incidents have been recorded in last year. Hence, existing Tjunction requires improvement to minimize this type of incidents, a fly over is suggested on this junction. Modasa by -passto shamalaji direction is very severe (right turning movement) on which maximum over turning incidents recorded. Therefor .geometric design and architectural design of the fly over bridge for this direction is incident in this study necessaryclassified traffic volume counts, geometrics details and accident data will be collected and accordingly design of fly overbridge will be carried out.
