An undivided rural multilane highway segment is to be widened so as to increase its existing lane widths from 9ft to 12ft. Compute the expected average total crash frequency after widening for the following conditions.

Expected average crash frequency before widening = 20 total crashes/yr

AADT on highway segment = 1800 veh/day

Proportion of total crashes constituted by CMF-related crashes = 0.65

Question 5 options:

	18.35 crashes/yr
	13.45 crashes/yr
	16.39 crashes/yr
	20.45 crashes/yr

TRP 631: HIGHWAY TRAFFIC OPERATIONS An existing six-lane divided multilane highway with a field-measured free-flow speed of 45 mi/h serves a peak-hour volume of 4,000 veh/h with 10% trucks (50% SUT, 50% TT). The PHF is 0.88. The highway has generally rolling terrain. What is the likely level of service of this segment? Good weather, no incidents, no work zones, and regular drivers may be assumed.

An existing 2-lane (in each direction) multilane divided highway. The speed limit is 50 mi/h, the lanes are 11-ft wide and lateral clearance is 2-ft. The peak hour volume is 1,800 veh/h in one direction, there are 5% trucks, a PHF of 0.92, but 1 access point per mile. a) Determine the LOS during the peak hour. b) Compare your result with the freeway in situation 1.

A section of a multilane highway is to be reconstructed to improve the level of service. The section being considered is on a 5.0% upgrade that is 3/4 mile long. The highway currently has 4-lanes (2 in each direction – all are 12-ft lanes) with a two-way left-turn lane in the middle and 4 foot shoulders on the right side. It is to be reconstructed into a 6-lane facility (3-lanes in each direction) undivided facility but, due to commercial development...

A highway in a rural town has a dangerous curve. Improving the highway will cost $10 million today, at time t = 0. The discount rate is r = .05 and a planning horizon of 10 years has been adopted. It is known that the new bridge will create benefits (due to a decline in deaths) of $1.5 million per year for each of the 10 years from t = 1 to t = 10. a. Compute the present value...

A state highway department is considering improvements to an existing highway in order to reduce the frequency of accidents on the highway. The type and frequency of accidents on the highway, studied over several years, showed that there were into three classes of accidents: fatal accidents, non-fatal injury accidents, and property damage accidents. On the average, there were 35 non-fatal accidents and 240 property damage accidents for each fatal accident. The calculated costs of such accidents embrace lost wages, medical...

4. The Indiana Highway Department wants to construct a new rural highway. The engineering team is considering two designs: a. Design A calls for a concrete pavement costing $90/ft. with a 20-year life, two paved ditches each costing $3/ft., three box culverts each costing $9,000/mile, annual maintenance costs of $1,800/mile, culvert cleaning costs of $450/mile every five years. Design A has a 20-year life. b. Design B calls for a bituminous pavement costing $45/ft. with a 10-year life, two sodded...

TRANSPORTATION ENGINEERING: A multilane highway has four lanes (2 in each direction) and a measured FFS of 55 mph. One upgrade is 5% and 0.62 miles long. Currently trucks are not permitted on the road, but there are 2% busses in the directional volume of 1900 vehicles (PHF is 0.80). Local authorities are considering allowing trucks into the traffic stream. If this is done, they estimate 150 trucks will use this highway during peak hour. Before trucks, the driver population...

A divided multilane highway in a recreational area (fp=0.90) has four lanes (two lanes in each direction) and is on a rolling terrain. The highway has 3 m lanes with a 1.8 m right-side shoulder and a 0.9 m left-side shoulder. The posted speed limit is 80 km/h. Formerly there were 3 access points per km, but recent development has increased the number of access points to 9 access points per km. Before development, the peak-hour factor was 0.90 and...
