Transit Technologies/Highway Options
A multi-modal approach, including transit and highway options, is important in providing travel choices in the future and for helping meet transportation demand in northern Colorado. Throughout the North I-25 EIS study, the project team considered a wide range of transportation alternatives. To effectively meet transportation needs in northern Colorado, the following transit and highway solutions have moved forward for detailed evaluation in the Draft EIS.
 |
Bus Rapid Transit
- Distinctive, specialized vehicles with flexibility,
frequency and speed of light rail
- Light rail-like stations provide fast and efficient
boarding
- Local/regional bus service which operates in shared
traffic or in an exclusive, fixed guideway
- Seats up to 70 people
- Average speeds up to 35 mph on arterials, 75 mph on
freeways
|
|
 |
Commuter Bus
- Standard 40' bus, articulated bus, or commuter coach
- Serves major highway corridors with fewer stops
- More regional service, longer distance trips
- Seats up to 60 people per bus
- Speeds up to 65 mph
|
|
 |
Commuter Rail
- Heavier, diesel or electric locomotive pulling passenger
cars
- Fewer stations than light rail, typically 5-10 miles
apart
- Regional service, with average trips of 20+ miles
- Seats up to 150 people per car
- Average speeds of 60-80 mph

Highway Alternatives |
 |
Tolled Express Lanes
- Single-occupancy vehicles pay a toll and high occupancy vehicles travel in the lane free of charge.
- A combination of both barrier and buffer-separated lanes are used to separate the Tolled Express Lane (TEL) from the general purpose lanes.
- Slip ramp access provides at grade access and egress between the general purpose lanes and the TEL.
- New capacity: 3,400 people per hour per lane
- Average speed: 60 mph
- Capital Cost: $7.4 million per lane mile
|
|
 |
General Purpose Lanes
- Most common method of adding travel capacity
- Standard paved lane that allows car and truck traffic
- New capacity: 2,400 people per hour per direction
- Average speed: 55 mph
- Capital Cost: $6.9 million per lane mile
