Solved in 2 steps
- What safety precautions are taken during handoffs between vehicles?Compute the minimum length of guardrail required to shield a hazard located 25 ft from the pavement edge of a one-way facility. The guardrail is to be located 12 ft from the pave- ment edge. Assume that vehicles will encroach at an angle of 11° to the pavement edge. If the roadway has two-way operation, what mininmum length of guardrail will be required?How is the safety of the handoff between vehicles ensured?
- Can you help me with the Work Break Down Structure (WBS) for a smart traffic management system?Q5a. Otwebeweate has been selected as the capital of a newly created district. As the new District Engineer, the Chief and the elders of the town approach you and make a request for the installation of a traffic light at one of the key intersections with the reason that there is no single traffic signal in the town and the installation of one will lift the status of the town as a district capital. What will be your decision and how will you explain it to the Chief and eldersWhen a vehicle that is presented for inspection will not fit in the building because it is too tall, the facility must: Notify DMV that they were unable to perform the inspection. Refuse to inspect the vehicle and suggest that the vehicle owner find a facility with a taller garage door. Bring the vehicle to a facility with a taller garage door for the vehicle owner. Inspect the vehicle outside of the building.
- What are the parameters in designing highway facilities and safety?Enumerate at least five safety features that you see on the road, then briefly describe each.A six lane highway (three 12-ft lanes in cach direction) has a superelevation of 6%, and a design speed of 60 mph. a) What radius should be used for the design of the roadway? b) If an obstruction is 12ft from the roadway edge, what SSD is available? c) Is there enough SSD available? If not, what should it be? Answer 10a: Answer 10b: Answer 10c:List the primary objectives and different functions of a freeway incident management program. List and describe 5 widely accepted incident detection algorithms.
- A large billboard is to be constructed by the side of a two-lane road, on the inside of ahorizontal curve, 27 feet from the edge of the innermost lane. If the road is located in aretirement community (where the design speed is 45 mph, the maximum superelevation is4%, lanes are 12 feet wide, and the expected perception-reaction time is 3.5 seconds), is thebillboard location acceptable?What safety measures are used when it comes to vehicular communications or communications between vehicles?Question 2 a) Name the four control measures an engineer can implement to encourage traffic calming? b) What is the ideal street width to create "yield street" in a residential neighborhood with low parking demand? c) Does research suggest that the installation of a yellow-centerline is associated with higher or lower traffic speeds?
