A System for Travel Time Estimation on Urban Freeways
… Systems (ATIS) applications. People traveling on urban freeways are interested in knowing how long it will take them to reach their destinations, particularly under congested conditions. Though many advances have been made in the field of traffic engineering and ITS applications, there is a lack …

Developing crash modification factors for operational parameters on urban freeways
… develops crash modification factors (CMFs) for urban freeways by considering level of service (LOS) deterioration due to change in hourly traffic volumes. Here, this study investigates LOS when it deteriorated from A to B, B to C, C to D, D to E and E to F using hourly volume and hourly crash …

Implementation Strategies For Real-time Traffic Safety Improvements On Urban Freeways
This research evaluates Intelligent Transportation System (ITS) implementation strategies to improve the safety of a freeway once a potential of a crash is detected. Among these strategies are Variable Speed Limit (VSL) and ramp metering. VSL are ITS devices that are commonly used to calm traffic …

Examining Route Diversion And Multiple Ramp Metering Strategies For Reducing Real-time Crash Risk On Urban Freeways
… strategy but also how to best apply them to an urban freeway. Route diversion was found to decrease the overall rear-end and lane-change crash risk along the network at free-flow conditions to low levels of congestion. On average, the two crash risk measures were found to be reduced between the …

Assessing Crash Occurrence On Urban Freeways Using Static And Dynamic Factors By Applying A System Of Interrelated Equations
… To account for the correlation between the disturbance terms arising from omitted variables between any two models in a category, seemingly unrelated negative binomial (SUNB) regression was used, and then the models in each category were estimated simultaneously. SUNB estimation proved to be …

Rethinking the Role of Urban Freeway: A Remediation of the I-5 Freeway in Downtown Seattle
Three major problems related to the urban freeway are discussed in this thesis. Firstly, the impact of air and noise pollution on people’s health has been increased by having freeways in cities. Secondly, urban freeways impede social and economic equity since they are most likely to be placed in …

Boulevards of Growth : Assessing the planned boulevardizations in Helsinki in the context of city-regionalism and land-use conflicts between municipalities
… the exclusion areas of highways to densify the urban structure and expand the urban core outwards. By turning urban freeways to boulevards, the exclusion areas can be built into residential areas that fulfil the need to densify the urban structure and cater to the need to produce housing into an …

The Impacts of Road Capacity Removal
… with a critical decision: do we repair or remove freeways from our urban centers? Freeway repair is exceptionally expensive, but removing a freeway is widely seen as a risky venture which may result in negative traffic effects. Therefore, it is necessary to gain a clearer understanding of how …

A framework for predicting urban freeway incident delays in real time
… simulation model. A dynamic extended model for urban freeways was proposed and tested that proved to model urban freeway traffic phenomena very well. This dynamic model was taken as the basis for a new on-line delay forecasting system. This research provides an architecture for incorporating a …
