About This Tool:

This is a user-friendly, sketch-level tool that allows transportation professionals to evaluate the relative emissions reductions achievable through various transportation strategies based on user inputs with regard to their scope, scale and expected impacts.

The quantification methodologies for these strategies are based on literature and employ emissions rates from the US Environmental Protection Agency’s MOVES emission model. The computations are designed to provide estimates of emissions reductions for a single analysis year.

The results are only meant to be indicative of magnitude of benefits for various strategies, and are not meant for official design or regulatory use.

Instructions:

Click on a strategy to navigate to its user inputs. The buttons located at the bottom of each worksheet allow you to result values, view results, and navigate between strategies. The "Results" tab provides outputs for all strategies for which data have been input.

Overview: This strategy places restrictions on the allowed idling time of trucks at truck stops or rest areas.

Note – While the inputs below are designed for truck stop computations, it can also be applied for a regional analysis of idling restrictions. For such an analysis, please enter total target fleet numbers in the “available parking spaces in truck stops” section; enter 100% as average utilization, and 1 for average daily number of trucks per spot.

Applicability: This strategy can compute emissions reductions for long-haul or short-haul trucks. It can be applied for a specific truck stop or rest area, or for a regional analysis.

Overview: This strategy adds bike facilities with an aim to increase bicycle use and consequently reduce automobile use.

Applicability: This strategy computes emissions reductions based on the reduced use of passenger cars and passenger trucks. It can be applied for a specific bike facility analysis, or for a regional analysis.

Overview: This strategy implements bike sharing programs that are aimed at increasing access to bicycles and making them an attractive transportation option.

Applicability: This strategy computes emissions reductions due to reduced use of single-occupancy vehicles (SOVs). It can be applied for a specific bike program analysis, or for a regional analysis.

Overview: This strategy adds HOV lanes to promote carpooling and reduce VMT due to increased vehicle occupancies.

Applicability: This strategy computes emissions reductions based on the reduced use of passenger cars and passenger trucks. It can be applied for a specific HOV facility analysis, or for a regional analysis of a network of HOV lanes.

Overview: This strategy locates various land uses adjacent to each other with the aim of reducing VMT through internal trip capture.

Applicability: This strategy computes emissions reductions based on the reduced VMT due to internal trip capture, and is applied for a specific mixed-use development.

Overview: This strategy improves signal timing to reduce vehicle delay and idling at intersections.

Applicability: This strategy considers emissions reductions for all vehicle types and is applied at a corridor level.

Overview: This strategy promotes the use of electric vehicles (EVs), whose emissions are lower than conventional vehicles.

Applicability: This strategy computes emissions reductions based on penetration of EVs in the vehicle fleet. It can be applied for a regional analysis.
