Current and projected traffic volumes are sufficient to cause level of service "F" (congested) conditions during peak periods now and into the future. (You can learn more about levels of service here.) However, flyovers are not considered to be a good option for this location. Thus, this ...
Retroreflectivity measured under the conditions of wetness with premium glass beads (RI 1.6-1.7) was similar to obtained with the retroreflective spots (RI 1.9) in spite of their increased RI, so even in such case there was no advantage of using the prefabricated elements; it might be ...
While regional pollution generates greater costs in uncongested conditions, on-road exposure comes to dominate health costs on congested freeways because of increased duration and intensity of exposure. The estimated marginal cost and benefit curves indicate a theoretical preference for price controls to ...
