South I-25 Build Alternatives

Supporting Measures

1. Transportation Demand Management

  • Flex time - A measure taken by employers that allows employees a flexible work-day (i.e. a work-day from 10 a.m. to 6 p.m.). This reduces traffic on the roadway during peak periods.

  • Paid parking - A measure used to encourage people to take public transportation rather than driving and paying a fee to park at their designation.

  • Carpool incentives - Measures taken to encourage drivers to carpool (examples include HOV lanes, discounted parking, and monetary incentives given by employers).

  • Vanpool programs - A program operated by employers or a transit service in which vans are used for transportation by people who live and work in the same neighborhoods.

  • Guaranteed ride home programs - A program offered by employers or a transit service that promises employees a way home if public transportation service has ended before the end of their work day.

  • Subsidies for transit passes - A measure in which employers encourage employees to use public transportation by paying for part or all of a transit pass.

  • Telecommuting - An option taken by employees to work from their homes. A popular option made viable by advances in the computer industry.

2. Transportation System Management

  • Park and ride lots - Parking lots that are provided for people to use public transportation or carpool.

  • Improve existing interchanges - Make changes to existing interchanges to improve operations or safety. (i.e. add double left turn lanes, upgrade type of interchange, repave roadway)

  • Improve existing underpasses - Upgrade or improve existing underpass structures along the interstate to improve operations or safety.

3. Intelligent Transportation System

  • Wildlife warning system - A device at known wildlife crossings that reflects vehicle headlights towards the wildlife that may be present along the side of the highway. The reflected lights scare the wildlife and discourage them from crossing the road.

  • Incident management program - A program that establishes policies and procedures to handle the detection and reaction of incidents.

  • Variable message signs - Signs operated by CDOT to relay important real-time information to drivers.

  • Ramp metering - Signals at on-ramps to meter traffic merging into the mainstream I-25 flow.

  • Real-time commuter information - Display travel time to specific destinations for commuters via radio, variable message signs, or the internet.

  • Traffic operations center - An office that collects, utilizes, controls, disseminates, and communicates information received from highway data collectors (weather stations, pavement sensors, video surveillance).

  • Emergency pull-offs with phones - Areas outside the interstate shoulder designated for emergency stopping. Emergency phones are located at these stops.

  • Road/Weather Information Systems - A system that provides pavement and weather condition information to transportation system managers and travelers.

4. Enhancements/Mitigation

  • Bicycle/ Pedestrian Trails - Special paths designated for pedestrians and bicyclists only.

  • Educational Signs/ Pull-outs - Signs and pull-outs along the roadway that identify and discuss sights and places of interest.

  • Wildlife Crossings - Signs along the roadway to alert drivers of known wildlife crossings.

  • Wildlife Grade-Separations - An overpass or underpass designed for wildlife crossings.

  • Noise Barrier/ Abatement - Barriers that provide noise protection for nearby residents and businesses.

  • Adequate Drainage - Drainage systems that are adequate for the chosen alternative.

  • Safety Barriers - Safety barriers along the interstate that protect the drivers from hazards. Examples include steel guardrail and concrete barriers.

  • Local Bus System - A bus system that provides transportation within a community, and to and from other alternative transportation modes (i.e. a bus that transports people from their homes to the local rail station).
