Road changes and trip changes run as two chains through the PU605 Unit 4 logic model for Safer Route 12, each box shaded by who controls it. Searches like "pu 605 unit 4 assignment example", "pu605 unit 4 sample" and "pu605 unit 4 example" land here.
What a finished PU605 Unit 4 logic model looks like
A single wide page holds the model; four pages of narrative follow. Columns run from inputs through activities, outputs, short-term outcomes and intermediate outcomes to a single long-term outcome, fewer pedestrians killed or injured on Route 12. The upper chain covers the road: a nighttime road safety audit, a formal request for pedestrian hybrid beacons at two crossing points residents identified, and continuous lighting. The lower chain covers the trip: a shift-change shuttle run with the distribution center, relocation of one bus stop, and a speed feedback program. Boxes the program controls are white, those depending on the state transportation district are gray, and outcomes neither can guarantee are hatched. A band along the bottom lists assumptions and external factors, including the state's construction schedule and the warehouse staying open.
How a PU605 Unit 4 example is structured
The narrative reads the model link by link, which is how the course generally expects a logic model to be defended. Each arrow is written as an if-then sentence, followed by its evidence and its weakest assumption. Road links draw on FHWA's Proven Safety Countermeasures, which list pedestrian hybrid beacons and lighting among treatments with documented crash reductions. Trip links rest on local evidence, chiefly the listening sessions, since published evidence for shift shuttles is thin. The resident test is described next: nine walk-audit participants heard each if-then sentence and said whether it matched how people actually move along the highway. Two links changed as a result. The beacon locations moved to where footpaths are worn, and a planned reflective vest giveaway was withdrawn once residents explained what walkers already wear.
Two chains on one page
Road and trip chains run in parallel and meet only at the long-term outcome, so a reader can see that the program could succeed on one chain while the other stalls.
Shaded by who holds the lever
White, gray and hatched boxes separate what the program delivers, what it must persuade the state to deliver, and what depends on drivers and weather.
If-then, read aloud
Every arrow becomes a sentence residents could accept or reject. The narrative records their verdict on each and quotes the two objections that changed the model.
A vest giveaway withdrawn
Most walkers already wear the warehouse's own high-visibility vests on the way home and are still hit. That fact removed an activity and moved attention toward speed and crossing gaps.
Assumptions along the bottom
The state's construction calendar, the warehouse's shift times and continued bus service are written as external factors, each tagged with the model box it threatens.
Where marks go in PU605 Unit 4
Shading earns this model marks that most logic models miss, because it shows graders the difference between activities the program runs and decisions it can only hope another agency makes. PU605 logic model criteria typically check that components are complete and correctly placed, that links are plausible and evidenced, that outcomes are measurable and that assumptions are explicit. Placement credit comes from keeping outputs as counts, beacons requested and shuttle trips run, and outcomes as changes. Link credit rests on the if-then narrative, which names evidence for each arrow and admits where it is local rather than published. The assumptions band covers the last criterion. Common losses: outcomes placed in the output column, arrows no narrative defends, a long-term outcome too distant to connect, and a model built without the community's hand in it.

PU605 Unit 4 questions, answered
What is the difference between an output and an outcome?
An output counts what the program did: sessions held, lights installed, trips run. An outcome describes change in people or conditions as a result: more people crossing at the beacon, lower speeds, fewer injuries. Placing a count in the outcome column is among the most common logic model errors graders flag, and it usually signals that the evaluation will measure the wrong thing.
How many columns should the logic model have?
Most templates use five or six: inputs, activities, outputs, and short-term, intermediate and long-term outcomes, sometimes with impact as a final column. Use the version your course provides. What matters more than the number is that each column holds the right kind of item and that every arrow between columns can be defended when questioned.
Should community members review the logic model?
Where the course emphasizes participation, as PU605 usually does, a review by people from the affected community is strong evidence that the model reflects real conditions. Describing who reviewed it, how, and what they changed shows participation at an actual decision rather than in general terms, and it gives the narrative a concrete test that graders can see.
