ALT CloudRaven Labs chart of Census LODES 2023 workplace primary jobs per primary job held by residents: Seattle 1.67, Bellevue 2.10, Tukwila 4.23. Tukwila has 42,504 workplace primary jobs and 10,044 held by residents. A table gives ACS 2020–2024 population, mean commute time, work-from-home and drive-alone estimates with 90% margins of error. Job relationships describe employment context, not measured daily trips.

ALT CloudRaven Labs evidence atlas. A map shows state-highway traffic sections in Seattle, Bellevue and Tukwila for ReportingYear 2023. One I-5 section in Tukwila has estimated annual average daily traffic of 239,000 vehicles. A second chart shows median 2021–2023 AADT changes at matched mainline sections: Seattle +4.4% (95 sections), Bellevue +6.8% (25), Tukwila +3.8% (25). These road samples do not measure citywide unique travelers.

ALT CloudRaven Labs side-by-side maps show resident density from ACS 2020–2024 and workplace primary-job density from LODES 2023 on full 2024 Census tracts. The maps use common density bins and the same scale. City-level residents/jobs per land square kilometer: Tukwila 902/1,787; Bellevue 1,752/1,727. A note reports that 1,024 of Tukwila's 1,464 reported crashes in 2023, 69.9%, were coded State Route. Area context does not establish individual travel or crash risk.

ALT CloudRaven Labs chart of modeled solar conditions for severe City Street crashes in 2021–2023. Modeled night accounts for Seattle 271 of 644 events (42.1%), Bellevue 18 of 67 (26.9%) and Tukwila 18 of 40 (45.0%). Seattle has one unknown solar time. The NOAA approximate model uses event date, local time, coordinates and daylight-saving rules. SDOT separately reported street lights on for 235 of Seattle's 271 modeled-night events. These are event shares, not travel-exposure-adjusted rates.
