Road from/to other road routes including bypasses.<br />

3. The trip matrices shall be worked out for each vehicle type information and<br />

weight for trucks should be summed up by commodity type and the results<br />

tabulated, giving total weight and average weight per truck for the various<br />

commodity types. The sample size for each vehicle type shall be indicated in a<br />

table and also in the graphical representations.<br />

4. The data derived from surveys shall also be analysed to bring out the lead and<br />

load characteristics and desire line diagrams. The data analysis should also<br />

bring out the requirement for the construction of bypasses.<br />

5. The distribution of lead and load obtained from the surveys should be<br />

compared with those derived from the axle load studies.<br />

6. The commodity movement data should be duly taken into consideration while<br />

making the traffic demand estimates.<br />

4.9.4. Turning Movement Surveys<br />

1. The turning movement surveys for estimation of peak hour traffic for the<br />

design of major and minor intersections shall be carried out for the Study. The<br />

details regarding composition and directional movement of traffic shall be<br />

furnished by the Consultant.<br />

2. The methodology for the surveys shall be as per IRC: SP: 41-1994. The details<br />

including location and duration of surveys shall be finalized in consultation<br />

with NHIDCL officials. The proposal in response to this TOR shall clearly<br />

indicate the number of locations where the Consultant wishes to conduct<br />

turning movement surveys and the rationale for the same.<br />

3. The data derived from the survey should be analysed to identify requirements<br />

of suitable remedial measures, such as construction of underpasses, fly-overs,<br />

interchanges, grade-separated intersections along the project road alignment.<br />

Intersections with high traffic volume requiring special treatments either<br />

presently or in future shall be identified.<br />

4.9.5. Axle Load Surveys<br />

1. Axle load surveys in both directions shall be carried out at suitable location(s)<br />

in each project road stretch on a random sample basis normally for trucks only<br />

(both empty and loaded trucks) for 2 normal days - (24 hours) at special count<br />

stations to be finalised in consultation with NHIDCL. However, a few buses<br />

may be weighed in order to get an idea about their loading behaviour. While<br />

selecting the location(s) of axle load survey station(s), the locations of existing<br />

bridges with load restrictions, if any, should be taken into account and such<br />

sites should be avoided.<br />

2. The axle load surveys shall normally be done using axle load pads or other<br />

sophisticated instruments. The location(s) of count station(s) and the survey<br />

methodology including the data formats and the instrument type to be used<br />

shall be finalised before taking up the axle load surveys.<br />

3. The axle load data should be collected axle configuration-wise. The number of<br />

equivalent standard axles per truck shall be calculated on the basis of results
