Transportation Engineering
(v) Length of railway track is considered independent of the road system and hence it is not subtracted to get the road length. (vi)A development factor of 5% is provided for future development. Result The total achievement was higher that targeted but NH and SH were constructed lesser than targeted. It should be noted than allowance for development of agriculture and industry during the next 20 years was made in Nagpur.
3. Third 20 years Road Plan (Lucknow Road Plan) [1981-2001] (i) Roads are classified in to primary, secondary and territory road systems. (ii) All villages with over 500 populations should be connected by all-weather roads. (iii) The overall road density was targeted as 82 Km per 100 square Km area. (iv)The NH network should be expanded to form square grids of 100 Km sides. (v) Express way should be constructed along major traffic corridors to provide fast travels. (vi)There should be improvement in environment quality and road safety. A. Primary Road System (According to Third Plan) (a) Express way of total length 2000 Km. (b) NH based on the concept of 100 Km square grids 100+200=300Km of NH length are provided per 100 x 100 = 10000 square Km area. B. Secondary Road System This includes 1. SH (State highways) 2. MDR(Major district roads) đ??´đ?‘&#x;đ?‘’đ?‘Ž đ?‘œđ?‘“ đ?‘†đ?‘Ąđ?‘Žđ?‘Ąđ?‘’ 3. (a) Length of SH in Km = đ??žđ?‘š2 25 Or (b) Length of SH in Km = 625 x no. of towns in state – length of NH 4. (a) Length of MDR in Km đ??´đ?‘&#x;đ?‘’đ?‘Ž đ?‘œđ?‘“ đ?‘ đ?‘Ąđ?‘Žđ?‘Ąđ?‘’ (đ??žđ?‘š2 )
= đ?‘œđ?‘&#x; 12.5 (b) Length of MDR in Km = 90 x no. of towns in state.
C. Territory Road system This includes (i) ODR (Other District Road) (ii) VR (Village Roads)
Classification of Roads
a. Classification of rural Roads The Roads are classified on the following basis (a) Traffic volume – Heavy, medium or light (b) Load transport- Class A , Class B (c) Location and junction. Nagpur Road plan classified roads on following 5 categories based on location and junction. 1. NH 2. S.H 3. MDR
