PE Transportation study plan

Compute saturation flow, capacity, v/c ratio, and control delay for a signalized intersection from given volumes, lane geometry, and phasing

Evaluate unsignalized intersection capacity and rank approaches by delay to identify the critical movement

Calculate yellow and all-red clearance intervals from approach speed, grade, and perception-reaction time, then build a two-phase timing plan that satisfies the minimum cycle length

Convert raw counts to peak-hour factor, design hourly volume, and directional distribution, and explain how each enters design decisions

Apply the eight MUTCD signal warrant categories conceptually to decide whether a signal is justified at a described location

Compute stopping sight distance, decision sight distance, and passing sight distance for given design speeds and grades

Determine minimum horizontal curve radius and required superelevation by balancing side friction and superelevation rate against design speed

Calculate crest and sag vertical curve lengths using K-values and rate-of-change criteria, then verify the curve fits the available sight distance

Lay out a superelevation transition (tangent runout, spiral or curve runoff) and check that the calculated length fits the curve length

Check a described cross section against standard lane width, shoulder width, clear zone, and side-slope criteria

Perform trip generation for a described development using published trip rates and compute entering/exiting peak-hour volumes

Distribute trips with a gravity model and allocate them to the network by assignment, showing the resulting link volumes

Apply a logit-style mode choice model to split person trips among drive-alone, transit, and non-motorized modes

Compute and interpret K-factor, D-factor, and design hourly volume for a planning-level roadway

Evaluate pedestrian and bicycle level of service indicators for a described corridor and recommend one improvement

Compute crash frequency, crash rate per million vehicle-miles, and crash rate per million entering vehicles for described sites

Screen a list of sites by both frequency and rate methods and justify which sites survive to the high-crash-location list

Apply the predictive-method structure (safety performance function, crash modification factors, calibration factor) to estimate expected crashes at a site

Select and rank countermeasures by crash modification factor and estimated benefit-cost, stating the assumption behind each factor

Classify collision types from a written crash narrative set and link each pattern to a plausible contributing factor
